Hi Microsim
can you tell me what is PFC used for and any advantages over SMPS ?
I was trying to make a supply from 12VDC to 30VDC at 5 Amps and I am not sure if a Boost converter would be good enough ?
one of my colleague was talking about PFC and how it can be used but it really went over my head.

regards

Hai microsim

can you give your pfc 1700 watt scheme, please help me

It was based on UCC28019, you can just make it, and it will work without issues.

You need to find a suitable gate drive circuit for the Mosfet.

Good luck
