Hello,

I am hoping that somebody can help me out.

I am trying to simulate a power supply in Ltspice and I am having a problem

This power supply is a zero voltage switching isolated full bridge converter.

It take 18-30Vdc in and outputs 165V at 120W (0.7A)

The problem that I am having is that the regulation poor. Also when the input voltage changes from 18 to 30 or vise versa the regulation does not seem to work at all.

Please see the attachment for the LTspice simulation file and schematic.
View attachment Power_Supply_3722-1 .zip

Thank you for your time and effort.

Regards;
Leo
