TL494 PWM Circuit

In this video PWM controller for inverter and dc to dc buck boost converter using TL494 IC, you can also use KA7500 IC both have same pinout.
This circuit consists of isolated voltage feedback with optocoupler and have current adjustment feature which can be used to make voltage and current controlled power supply. In my case output frequency is 36KHz which is very useful for high frequency inverter and high efficiency dc to dc buck boost converter.
