Hi Ernest,
Sorry my delayed response. The PMP7391 design uses output diodes. If the diodes were replaced with synchronous rectifiers and careful redesign 95% should be possible with an active clamp forward.
However, an easier path to a solution might be…
Part Number: UCC2894 Other Parts Discussed in Thread: PMP7391 , , UCC2897A Hello,
Looking for Active clamp Forward (High Side) design for 300VDC to 400 VDC input with 24V / 300W output. Came across PMP7391 reference design.
Need any excel or MathCad based…
Part Number: PMP7391 Hello we are working on the AC/DC Converter with reference to the PMP7391
It will be helpful if you can provide the application note and Layout design file

any topology reccomendation?
DCin = 390V
variable output voltage 0-50V
i was thinking about active flyback.
It should be ZVS / ZCS. For best efficiency…
Hello sean yiwu
There is a reference design available
http://www.ti.com/tool/PMP7391
and this shows how to use the CS pin to limit the MOSFET current.
This design will show you how to achieve over current protection
