Hello,
I am designing a 330W flyback. (Vin = 180-373VDC, Vout = 80V, 4A)
The problem is that at light load the RCD clamp dissipates about 2.8W.
So i have come up with this switchable RCD clamp.......

Can you see any problems with this?
Is it OK?
Here is the LTspice simulation file in .txt formar, so converting to .asc allows it to be run in LTspice
