Hi,

I have designed a power supply for dual output of 52V, 0.4A and 7V, 0.25A, using the PI Expert tool. I have attache d the schematics and layout images below .
Also I have attached the waveform I see at the secondary side of the transformer (52v line).

Can anyone tell me what could be going on?

Thanks

Sorry forgot to attach the wave forms
