Part Number: UCC28740

Hi TI,  In my design I'm using two parallel MOSFET (800V 17A Part no. TK17A80W) & Transformer Primary Inductance: 55uH

I have changed the snubber value but there is not effect in the overshoot. Still overshoot is high around 750V. Here I am attaching the calculation sheet and components details which I am using now in my design. Kindly have a look. If I am doing anything wrong pls suggest.
