Overview: The article discusses the importance of maintenance in ensuring the reliability and safety of power electronic systems. It outlines the steps involved in maintenance, including condition observation, anomaly identification, defect diagnosis, and remaining useful life prediction. Power electronic systems are subject to a variety of risks, including catastrophic failures, despite the careful consideration of dependability characteristics during design and control. This is because of the complex and demanding operating settings of power electronic systems. For field applications, power electronic components, converters, and systems must be extremely reliable and safe. What are the steps in maintenance to make the power electronic system more reliable?Preventive maintenance systems are useful ways to guarantee that planned functions are carried out as intended. The steps in maintenance of power electronic system includesCondition observationIdentification of anomaliesDiagnosing defectsRemaining Use Life (RUL) predictionThe above actions coincide with the IEEE standard framework of prognostics and health management for electronic systems. Condition ObservationPower electronics condition observation consists ofIdentification of system parametersPreprocessing dataMining featuresThe data from the condition observation is used to discover informative and hidden patterns that form the foundation for the prognostic and health management applications that follow. Identification of System ParametersIdentification of system parameters involves the gathering of data for important components.Characteristics of power electronic systems includesExtremely small space inside a power moduleExtremely fast switching frequencyRelatively insignificant parameter changes in terms of aging, etc.Because of these characteristics, developing specific hardware for parameter identification is quite a challenging task.A noninvasive approach that uses existing physical signals to indirectly get information or estimate relevant information without the need for additional hardware implementation is one of the more promising methods.Therefore, a sensorless and cost-effective option can be used for condition monitoring, which is good for people who work in industry. In general, there are two types of methods for identifying system parameters:Model-freeModel-based. Preprocessing data and Mining featuresThe goal of data preprocessing and feature mining is to improve the quality of the raw data so that it can be used for applications like problem diagnostics.Improving the quality of data involves the following steps to make it more organized. The steps are as followsData cleaning to minimize noiseData clustering is used to find groups of related data pointsDensity estimation is used to determine the distribution of the dataData compression to reduce the number of features by projecting large-sized data to small-sized dataData fusion to combine various information sources, and moreWhen data preparation and feature mining are done correctly, the performance of the ensuing prognostics and health management applications—such as diagnostic accuracy—can usually be greatly enhanced. Identification of Anomalies and Diagnosing DefectsThe anomaly detection process focuses on identifying unusual patterns and making a binary decision. When the nominal parameters or rated system characteristics exceed the predetermined safety range, it gives an indication.The fault diagnosis finds and identifies the specific failure modes after the unusual changes happen.The classification, regression, or clustering tasks are essentially anomaly detection and fault diagnosis. When a new fault signature arrives, it identifies the fault label based on the learned relationship from the training stage.Anomaly detection and fault diagnosis techniques fall into two categories:Supervised learningUnsupervised learning Remaining Useful Life (RUL) PredictionIn the design phase, lifetime prediction serves to support the characteristics of a population of units known as the ‘Design for Reliability’. It is one of the crucial components of prognostics and health management.The purpose of the estimation of RUL is not to accurately predict the lifespan of a population of units. Based on condition monitoring data, it predicts the remaining lifespan of each single unit in operation. For applications where availability, safety, or reliability are crucial, RUL prediction is used as an extra tool to lower uncertainty.The lifetime estimate is subject to several challenges, such asInaccuracies in model calibrationManufacturing tolerancesDifferences in operational environments and workloadWhen a particular unit is operated in the field, these uncertainties lead to inaccurate reliability estimations. The following areas require greater attention in order to improve the practicality of AI-based RUL prediction techniques for field applications. Quantification of uncertaintyFor RUL prediction, being able to measure uncertainty is more important than for other regression-related tasks, like control functions. Since the RUL is a random variable, quantifying the confidence interval is crucial for making the best decisions.All of these uncertainties—due to population heterogeneity, measurement noise, various operating settings, etc.—should be considered in a workable practical solution. Quantifying the uncertainty using AI algorithms is quite difficult.A few practical options areThe use of particle filters in neural networks (NNs)Bayesian-based artificial intelligence techniques (e.g., Gaussian process, RVM)Monte Carlo methodsStochastic data-drivenStochastic, data-driven approaches are an interesting option to explore. These approaches can naturally yield the probability density function of the RUL for the purpose of computing the confidence interval. Adaptive capabilityThis is the crucial stage for real-world applications and is related to the model parameter tuning layer in Fig. 1 that connects the offline and online models. If an AI approach lacks adaptive flexibility, its use is limited.Power electronics have difficulties because the operational conditions of the training dataset, which is often acquired through accelerated testing trials, differ significantly from those of the in-situ system (i.e., the test data). Most of the research makes the assumption that the in-situ system's operational parameters are the same as those of the training dataset, which could not be the case in real-world applications.Therefore, the AI-based RUL prediction method's adaptability is essential for bridging the gap between research in academia and practical implementations in industry.Detailed mapping relationship derivations and transfer learning of degradation characteristics under different operating settings (temperature, voltage, humidity, etc.) are also interesting ways to tune model parameters. This means that system models need to be studied in great detail.Fig. 1 shows a methodical flowchart of power electronic system maintenance tasks. It typically comprises the three elements listed below.             Summarizing the Key PointsMaintenance of power electronic systems involves condition observation, anomaly identification, defect diagnosis, and remaining useful life prediction to ensure reliability and safety.The IEEE standard framework for prognostics and health management is applicable to power electronic systems, emphasizing the importance of a comprehensive maintenance approach.Data preprocessing and feature mining are crucial for improving the quality of raw data, enhancing the performance of prognostics and health management applications.AI-based remaining use life prediction techniques face challenges in real-world applications, requiring quantification of uncertainty and adaptability.Power electronic systems require an adaptive maintenance strategy to bridge the gap between research and practical implementation in industry, addressing operational parameter variations. ReferenceZhao, Shuai, Frede Blaabjerg, and Huai Wang. “An Overview of Artificial Intelligence Applications for Power Electronics.” IEEE Transactions on Power Electronics 36, no. 4 (April 2021): 4633–58. https://doi.org/10.1109/tpel.2020.3024914.

Overview: This article discusses the challenges faced by smart grids. It also briefs on how the Energy Internet and the use of blockchain and IoT technologies are potential solutions to smart grid security challenges. A decade ago, the idea of a "smart grid" was the foundation of bright dreams, now, it's the most talked-about issue in the industry of renewable sources. The smart grid is a multidimensional energy infrastructure idea that can be implemented using a wide range of available technologies. The incorporation of a "smart grid" into today's electrical infrastructure is crucial for the following reasons: What are the challenges faced by smart grids?Skepticism Among Industries First of all, industries are still hesitant about the advancement of smart grid projects. The misconception among industries is that government commitments cannot be fulfilled and that smart grid projects are moving slowly forward. Furthermore, despite the fact that governments fund the creation and testing of smart grid pilot projects, the industries engaged in the installation of these projects have little passion for investing in the technology, which has an impact on the system's development. Security Issues Second, there are numerous security risks and associated difficulties that can affect the architecture and infrastructure of smart grids. Threats and difficulties include terrorism, theft, disasters caused by nature, and cyberattacks. An actual security breach may result inPower outagesA breakdown in the information and technology infrastructureDisruption in the power marketNetwork cascade failureEndanger human safety In summary, issues with technology privacy, permission, and authentication are identified as smart grid security challenges. The Energy Internet may also have similar problems, but using technologies like blockchain and the Internet of Things (IoT) should make security breaches less likely and less harmful, and they should also make recovery easier with little assistance from humans. Decreased Penetration of Electric Vehicle Thirdly, a barrier to the widespread use of electric vehicles in the energy sector is the low market penetration of these vehicles with vehicle-to-grid (V2G) capability. Repeated charging and discharging of the battery is necessary for effective V2G operation, which results in battery deterioration. Even though scientists are optimistic about lithium-ion (LFP) batteries, more study is needed to determine how to maximize the battery life of V2G-enabled vehicles for the technology to be implemented effectively. Complexities Posed by Microgrid Fourth is using micro-grids to improve smart grids. The installation of microgrids with smart grids presents few technological and regulatory hurdles. Inbalanced supply and demand can lead to issues with frequency and voltage in microgrids. When generators are connected and disconnected using a "plug-and-play" feature, these issues may worsen. Variations in the power production from the connected renewable energy systems make it difficult to maintain a steady state for the microgrid. Furthermore, a greater proportion of renewable energy could cause transmission and distribution difficulties in the current network. The incorporation of suitable protection devices becomes essential as the system becomes more complicated. Because micro-grid infrastructure comprises a bi-directional power flow, the protection mechanism differs from standard power systems. Additional information on micro-grid protection schemes should also be considered. Development of Strandards Lastly, it is necessary to address the issues raised by the regulation of communication devices, cyber-security devices, and compatibility and conformity to standards. Countries have assigned various groups the task of creating standards for smart grid interoperability. The design, development, and production of devices that meet international standards is one of the main obstacles to deploying smart grid infrastructure. The Energy Internet The Energy Internet is allegedly able to solve many of the aforementioned problems. It serves as the energy system's forthcoming revolution. It will make it possible to put less focus on large-scale centralized power generation and more on numerous tiny, dispersed generation systems. Government investment in generating facilities may be minimized as a result of prosumers now owning a larger portion of the power generation industry. Households and other small-scale users who can construct local power plants to buy and sell electricity are encouraged to invest via the Energy Internet. By doing this, governmental organizations' investment burden is lessened when they spend on building infrastructure. It provides advanced capabilities to facilitate flawless electricity exchange through the Energy Internet. Current security threats and challenges are addressed when this infrastructure is supported by innovative technologies like blockchain and IoT. However, as technology develops, new security threats are probably going to appear, and ongoing cybersecurity innovations are going to address them. Research in the field of Energy Internet helps optimize storage devices to reduce battery wear. The Energy Internet can also use distributed energy systems management algorithms to best address ongoing smart grid issues brought on by the unpredictable and variable nature of renewable energy systems. Future integration of artificial intelligence (AI) and machine learning (ML) algorithms into the Energy Internet, which provide additional support. Lastly, government agencies must coordinate with other relevant international entities to address the concerns of standardization and interoperability. Energy Internet can fill up the gaps left by the smart grid's shortcomings. Management of Energy Internet Markets The markets for green gas, liquid fuels, and renewable heating in the future will affect the power market. The Energy Internet has the ability to reconfigure itself into a multi-energy system in this regard. A fully operational energy market for the energy cells can be integrated into the Energy Internet architecture. As an illustration, the current electricity exchanges in some countries operate using an auction-based bidding system. This technique works well in static liberalized markets where it is simple to predict the market structure and network architecture. Energy cells that are integrated with the Energy Internet, however, are diverse in character and have competing objectives. Auction-based bidding might not be an effective market mechanism given this feature. Game-Theoretical Algorithms A real-time power price that reflects the dynamic supply and demand balance is one potential option. The selection of game-theoretical algorithms to establish an appropriate real-time pricing mechanism for trading among energy cells on the Energy Internet is one suitable option. Game theory models have been used to examine studies that deal with disagreements involving interactive decision-makers. In recent years, the scalability of game-theoretic algorithms has facilitated their widespread use in energy market design. The mathematical model for the day-ahead market for the competitive energy cells was developed using the Nikaido-Isoda function (NIRA) and the Relaxation algorithm. For more than three decades, businesses have relied on a specific group of numerical algorithms known as relaxation algorithms. Earlier efforts in the relaxation method greatly illustrate the technique's quick convergence and reasonable accuracy. The bilateral Shapley value and kernel are used to make sure that profits are shared fairly among consumers who work together. Blockchain Technology Virtually anything of value can be recorded in the blockchain, an uncorruptible digitally distributed ledger of economic transactions. The shared ledger that is published to every member is the foundation of how blockchain technology operates, as shown in Fig. 1. Fig. 1. Centralized transaction vs. blockchain transaction Source: IEEE Access It uses smart contracts to make sure that participants follow the rules, a distributed consensus method to make sure that everyone agrees on the proposal, and cryptography-based safety measures to make trade easier. As a result, it offers the customer a private cybersecurity solution that is strong and resilient. Additionally, blockchain reduces the possibility of double-spending that comes with digital currencies. The computation-intensive algorithm is necessary to mitigate the possibility of double-spending. New blocks are added to the blockchain, and transactions are validated using this computational technique. Specialists compete with one another to solve problems and validate these transactions. Additionally, blockchain offers attributes likeTransparency, which makes data easily auditable,Redundancy, which distributes a copy of data to all participants to prevent third-party malpractice,Immutability, which makes record alteration exceedingly difficult,Disintermediation, which does away with intermediaries like banks or energy utilities,Blockchain technology offers continuous traceability of all energy transactions as well as a comprehensive transaction record for the energy markets. But there are still some issues with the technology. Among the difficulties are those related toDigital data and metadata storageNetwork effect problemsCopyright disputesLegal concernsSummarizing the Key Points The Energy Internet can address ongoing smart grid issues brought on by the unpredictable and variable nature of renewable energy systems.Prosumers owning a larger portion of the power generation industry can minimize government investment in generating facilities.Blockchain and IoT technologies can make security breaches less likely and less harmful, and they should also make recovery easier with little assistance from humans.Disintermediation and blockchain technology offer continuous traceability of all energy transactions as well as a comprehensive transaction record for the energy markets.Difficulties related to digital data and metadata storage, copyright disputes, network effect problems, and legal concerns still exist with blockchain technology.Reference Joseph, Akhil, and Patil Balachandra. “Smart Grid to Energy Internet: A Systematic Review of Transitioning Electricity Systems.” IEEE Access 8 (2020): 215787–805. https://doi.org/10.1109/access.2020.3041031.

From predictive maintenance and fault detection to energy management and personalization, AI and ML are transforming the electrical and electronic industry in unprecedented ways. This article provides an overview of the role of AI and ML in the industry, examining their applications, benefits, and prospects.To start with let us understand what the terms AI and ML mean and how they are different.What are AI and ML?Artificial intelligence (AI) and Machine learning are often used synonymously although there are some differences between these two terms. To understand AI, it is important to first define what is machine learning and differentiate it from artificial intelligence.Artificial Intelligence is commonly known as AI, which refers to the development of computer systems, embedded systems and logical processing that can perform tasks that typically require human intelligence, such as learning, problem-solving, decision-making, and language processing.  For computer systems to learn and mimic human intelligence, they need to learn from a large dataset. For computers to learn from data, adapt to changing settings, and carry out activities that would otherwise require human involvement, artificial intelligence (AI) entails the creation of algorithms, machine learning models, and other approaches. Self-driving cars, voice recognition, image and speech recognition, fraud detection, and many more uses for AI are becoming more prevalent.Machine Learning or ML for short is a basic subset of AI. Basically, it involves the design and development of simple or complex algorithms and models that enable computers to learn from data, make analyses and improve their performance on a task without being explicitly programmed. Machine learning algorithms can learn from a large dataset to identify patterns, correlations and relationships, and then use that knowledge to make predictions or decisions on predictive new data. Machine learning can thus be described as a way of predicting the future based on presented parameters. There are three main types of machine learning: supervised learning, unsupervised learning, and reinforcement learning. ML is used in a wide range of applications, including image and speech recognition, natural language processing, recommendation systems, and predictive maintenance, among others.Artificial Intelligence and Machine Learning in the Electrical and Electronics IndustryThe term artificial intelligence as used in the electrical and electronics industry generally refers to a variety of systems and technologies built to imitate human intelligence by making decisions and solving related problems. In recent years, engineers and scientists have explored different applications and ways in which AI can be applied in electrical systems.Some of the most common ways in which AI is incorporated into electrical systems and consumer electronics:• Expert systems: Expert systems are a subset of artificial intelligence (AI) systems that employ an inference engine to derive conclusions from a knowledge base containing data on a particular area. If-then rules that are drawn from the knowledge of human subject-matter experts often make up the knowledge base. To offer a solution or suggestion, the inference engine applies these principles to the data or issue at hand.

The original ATX standard included a 20-pin connector with a layout that was very similar to the 24-pin connector but excluded pins 11, 12, 23, and 24. This means that the newer 24-pin power supply is beneficial for motherboards that require more power, eliminating the need for ATX 12V power supplies to include an auxiliary power cord (although some still may). 24 pin connector The extra four pins are often detachable, allowing it to be utilized with a 20-pin motherboard connection. The extra pins simply dangle from the motherboard connector; they do not plug into another slot. Some motherboards allow the older 20-pin power supply cable to be used on a 24-pin motherboard connector. If you need to utilize a 24-pin power supply connector on a motherboard that only supports a 20-pin cable, you can buy a 24-pin to 20-pin converter from a variety of internet suppliers. 9.2 Frequently Asked Questions about 24 Pin Connector1.Can I use a 20 pin connector on a 24 pin motherboard?You can connect a 20-pin cable to a 24-pin motherboard and it will function properly. At least for the time being. They included the extra four pins for a reason. When you insert a 20-pin cable into a 24-pin connector, you are not providing the extra current carrying capacity that the motherboard may require. 2.Do all motherboards have 24 pin connectors?Almost all new power supplies on the market today include a 24-pin power connector for connecting to a computer motherboard. Some motherboards, however, still include a 20-pin ATX power connector. Fortunately, practically all 24-pin power connectors are constructed with four pins that may be disconnected or moved out of the way. 3.How do you remove a 24 pin connector?I did it by pushing the clip, wriggling the connector from side to side, and finally pulling the connector out. If the connector still won't budge, push the clip and wiggle some more. Make certain that you are pushing the clip the entire time. 4.What is the function of 20 24 pin Molex connector?On ATX motherboards, the Mini-Fit Jr. connector can be utilized as the main power connector in 20/24-pin layouts. The same connector design, in single or paired 4-, 6-, or 8-pin combinations, can be used for additional CPU and graphics card power. 5.What is the difference between a 24 pin and a 20 pin motherboard power connector?The 24 pin motherboard connector is essentially a 20 pin connector with four extra pins added to the end. The original 20 pins remained untouched. The additional four pins are not independent rails. They are simply additional lines to give more current to the same rails. Ⅹ ConclusionThere is a wide range of connector types: they can feature holding devices such as pegs, they may require selective soldering, and some are even a "hybrid" of SMT and through-hole. All of these variations can make connectors more difficult to assemble on a PCB, thus it is critical to be aware of potential manufacturing challenges when selecting a connector. When selecting a connector, keep the following points in mind:1) Avoid using through-hole connectors because they have the highest manufacturing costs. Typically, all-SMT designs are less expensive to construct. Even if through-hole components appear to be less expensive, additional production expenses often eat into any savings. 2) Steer clear of connectors that require selective soldering. A connector that requires selective soldering in an otherwise all-SMT design necessitates the assembler doing an SMT/reflow pass, followed by another pass with selective solder. Masking out the components may necessitate additional work. All of this can raise prices and potentially lower yields. 3) Select "pure" SMT connectors devoid of holding features (such as pegs). SMT connectors with retaining components are often more expensive to install. Not all of these components are compatible with all pick and place machines. If using retaining components is required, make the receiving holes as large as possible. Assemblers can and will utilize SMA (surface-mount adhesive) when employing SMT connectors since it is usually strong enough to give more than enough physical strain relief and typically incurs no extra work.
