IntroductionHow to Read an Electrical Diagram LessonCircuit diagram is the basic of engineering research and planning. A schematic layout diagram, which is drawn with the standard symbol of physical electricity, can show the working principle of each component and device relationship, and provide pl ...
Schematic DiagramsCLC П-Filter1. Working Principlea. When the positive pulse is input, C1 is charged first, the charging current is ic1, and meanwhile, reaching the peak voltage of pulse. The inductor L also has a linearly increasing current, and the magnetic energy is stored in L. With the increase ...
IntroductionThe heat sink has a thermal conductor that carries heat away from the device into fins that provide a large surface area for the heat to dissipate throughout the rest of the components, thus cooling both the heat sink and processor. Both a heat sink and a radiator require airflow and, th ...
IntroductionMany engineers who have not used the switching power supply may have some worry about it, such as the PCB layout, the parameter and type selection of components and so on. In fact, as long as you understand the basic principle, the use of switching power supply design is very convenient. ...

A short vedio to know something about a/d converter:Electronic Basics: ADC (Analog to Digital Converter) The process of converting analog to digital is called the analog-to-digital converter, and the circuit that completes the conversion is called the A/D converter (abbreviate  ADC). Its f ...
IntroductionMCU(microcomputer) is an integrated circuit chip. It integrates the microprocessor(CPU), which has data-handling technology such as arithmetic, logic and data transfer , etc, random access data memory(RAM), read-only program memory(ROM), input and output circuit (I/O port) that using the ...
AbstractThis paper introduces a switching power supply with half-bridge circuit. Its input voltage is AC 220V ±20V, the output voltage is DC 4V ~16V, the maximum current is 40A, and the working frequency is 50kHz. And its design idea, working principle and characteristics of the power supply are int ...
