Other Parts Discussed in Thread: UCC28051
Dear Ulrich
I am wondering if I could design a circuit with PFC function using UCC28780.
However, I'm thinking of a one converter, not a two converter.
UCC28780 works in CrM MODE, so I think I can implement PFC function if I can prepare a multiplier.
How about it?
We believe that the one-converter method contributes to downsizing.
The PMP2614 is an isolated opto-less single-stage PFC flyback.
This is an image of adding an active clamp to this circuit.
Or is it more advantageous to adopt the 2-converter method? (due to cost, size, design difficulty...)
It is a power supply with 200W output.
You are a genius, so I would like some helpful advice.
