LM324 Application Circuit Analysis LM324 can be composed of the proportional amplifier circuit, proportional integral circuit, adder circuit and so on. Below we will analyze the specific application circuit of LM324 in the DC speed regulation circuit. 5.1 Zero Blockade Circuit The function of the zero blockade circuit is to prevent the motor from crawling due to factors such as temperature drift of the components in the control circuit. The basic circuit is shown in Figure 3.Figure 3 Zero blockade circuit Since the feedback resistance R5=2 MΩ, the zero blockade circuit is similar to a voltage comparator. When UB=+15 V,  That is, the non-inverting input of the operational amplifier is 0.29V, and the inverting input is Ug'. The range of Ug' is -9.7~9.7V. When Ug'<UA, that is, Ug'<0.294V, UB=+15V, diode VD3 turns on, UO1=14.7V. When Ug'>UA, that is, Ug'>0.294V, UB=+15V, diode VD3 is off, UO1=0V. 5.2 Given Integrator Circuit The function of the given integrator circuit is to change the abrupt signal into a continuous and slowly changing signal to prevent the sudden addition of the given signal from causing the output voltage to rise, causing the motor to overcurrent. The basic circuit is shown in Figure 4. Figure 4 Given integrator circuit The given integrator circuit is composed of voltage comparison circuit Ug', C5 integrator circuit and a feedback circuit. The given voltage is filtered, and then after the anti-interference correction network composed of R10, R11, and C6 without delay, it acts on the buffer composed of IC1B, R11, Rp6 for buffering. Adjusting Rp6 can change the integral constant (integration time), and then output through the integrator composed of IC1D, C7, C8, etc. and finally output the C02 voltage through the calibration network again. When Ug'≤0, UA=-15V. Due to the function of diode VD6, U02=UUg'+0.7V, and the adjustment range is -9.7~+9.7V. When Ug'≥0, UA=+15V. Due to the feedback resistor R18, U02=Ug', and the adjustment range is -10V to 0V.5.3 Voltage Comparison Circuit The basic circuit is shown in Figure 5.Figure 5 Voltage comparison circuit This circuit is a hysteresis voltage comparator, input signal Ub3=Ub1+Ub2.  When Ub3<-0.29V, UB=+15V, Ub4=14.3V, when Ub3>-0.29 V, UB=-15V, Ub4=0V. The function of the hysteresis loop is anti-interference, and the loop width of the sub-circuit is only about 0.6V. 5.4 Adder and Limiter Circuit (1) The role of the adder: the role of the filter regulator is to output voltage U01 to the zero-blocking circuit, output U02 to the given integrator circuit, output voltage U03 to the voltage negative feedback circuit and current cut-off negative feedback circuit, and amplify the integrated voltage Uk of the output voltage U04 of the protection circuit to obtain the control voltage Uk to control the control angle of the trigger pulse, thereby controlling the output voltage of the thyristor DC drive device. The adder and limiter circuit is shown in Figure 6. Figure 6 Adder and limiter circuit (2) Analysis of the working principle of the adder: The circuit is an adder composed of an integrated operational amplifier and a non-polar capacitor composed of capacitors C9 and C10 in reverse series, which plays a filtering role in the circuit. The control voltage is: The function of the limiting circuit is to limit the maximum output value of the UK voltage by adjusting the potentiometer Rp1, and adjusting the potentiometer Rp2 can limit the minimum negative output value of the UK voltage. Adjusting reasonable positive and negative limiting voltages can control the minimum control angle αmin and the minimum inverter angle βmin.  VI.

A separate supply input is provided for the logic, allowing operation at a lower voltage and internal clamp diodes are included.This device is suitable for use in switching applications at frequencies up to 5 kHz.L298N BasicsThe L298 is an integrated monolithic circuit in a 15-lead Multiwatt and PowerSO20 packages. It is a high voltage, high current dual full-bridge driver designed to accept standard TTL logic levels and drive inductive loads such as relays, solenoids, DC and stepping motors. Two enable inputs are provided to enable or disable the device independently of the input signals.The emitters of the lower transistors of each bridge are connected together and the corresponding external terminal can be used for the connection of an external sensing resistor. An additional supply input is provided so that the logic works at a lower voltage.L293D vs L298NThe basic difference between the L293D and the L298N motor driver:L293D Drivers can operate from 4.5V to 36V, while L298N can operate at up to 46V.Maximum 600mA Current can be drawn from both L293D channels, while L298N Motor Driver can draw up to 2A from both channels.L293 is a quadruple motor driver that uses a half-H driver while L298 is a dual full-H driver, i.e. in L293 all four input-output lines are independent while in L298 the half-H driver cannot be used independently, only a full H driver must be used.As the output current of L293 for each channel is 650mA, whereas it is 2A for L298. The heat sink is therefore provided by the L298 motor driver.EMFs are supplied internally in L293D but must be provided externally in L298.L293D is suitable for small current drawing motors such as the BO motor, DC motors up to 500 RPM and small stepper motors which take less current up to 600mA at their highest torque rating. Whereas L298N has the advantage of higher output current up to 2A and is therefore suitable for high torque and high RPM motors such as Johnson motors and high torque DC Geared motors.L293D vs ULN2003L293D & ULN2003 DatasheetL293D DatasheetL293D Push-Pull Four Channel DriverULN2003 DatasheetULN2003 Seven Darlington ArraysL293D BasicsThe Device is a monolithic integrated high voltage, high current four channel driver designed to accept standard DTL or TTL logic levels and drive inductive loads (such as relays solenoides, DC and stepping motors) and switching power transistors.To simplify use as two bridges each pair of channels is equipped with an enable input. A separate supply input is provided for the logic, allowing operation at a lower voltage and internal clamp diodes are included.This device is suitable for use in switching applications at frequencies up to 5 kHz.ULN2003 BasicsThe ULN2003 is a high-voltage, high-current Darlington array which containing seven open collector Darlington pairs with common emitters.

Each channel is controlled by a TTLcompatible logic input and each pair of drivers (a full bridge) is equipped with an inhibit input which turns off all four transistors. A separate supply input is provided for the logic so that it may be run off a lower voltage to reduce dissipation.L293D vs L293BOne of the very common H-bridge ICs available in the market is L293B or L293D. It is in fact a double H-Bridge, since motion of two motors can be simultaneously controlled on each half. While interfacing with Microcontrollers GND (0 V) and voltage supply to the motor is needed in H-Bridge since input is being provided from microcontroller.The L293D is rated as 0.6A per motor. The L293B can handle 1 amp per motor but their pins seem to be different, and the way the motors must be connected seems not to be the same.L293 ( no D) is comparable to L293B. Both will need external diodes.L293D has internal diodes and the lower current rating.L293D vs L293EL293D & L293E DatasheetL293D DatasheetL293D Push-Pull Four Channel DriversL293E DatasheetL293E Push-Pull Four Channel DriversL293D BasicsThe Device is a monolithic integrated high voltage, high current four channel driver designed to accept standard DTL or TTL logic levels and drive inductive loads (such as relays solenoides, DC and stepping motors) and switching power transistors.To simplify use as two bridges each pair of channels is equipped with an enable input.
