I made a push-pull converter using sg3525a.
my problem is the output voltage will drop when I connecting 100-watt load or more.
input voltage is 24 volt and the output is 350 volt. the frequency is 100khz. using MOSFET irfp4568. using RC snubber with c=6 nF and R=2.5ohm. and driving the MOSFET with hcpl3120 positive and negative gate voltage. I am using ferrite core EE 55/28/21 to get 1kw output power.
