in this video i explained how is the feedback loop works in switch mode power supply. in smps the output ripples from the output of the rectifier are taken to to the optocoupler and the tl431 provides a offset voltage level to the optocoupler when the reference is maintained by the voltage divider network gets the regulated output level from the output filter capacitor. these ripples are transferred to the feedback pin of the smps pwm pulse width modulator ic, which adjust its output duty cycle to adjust the output voltage of the smps
after watching this video you will be able to:-
