{315} How SMPS starts and regulates the voltage

{315} How SMPS starts and regulates the voltage. in this tutorial i shared Switch Mode Power Supply SMPS working principle (Soft start startup, running & feedback)
how smps takes soft-start using startup resistor, then takes vcc voltage from auxiliary winding and finally takes feedback signal to maintain the output voltage
basic working concept of smps switch mode power supply
how smps start up circuit works
smps vcc voltage path
smps voltage regulation concept
