hi everyone,
I have designed a push-pull converter but i am running issues recently. Without load, I am able to read 340VDC as expected. As long as I include the load, voltage drops significantly. When I pull 100mA, the voltage drops to 310 V. When i pull 200mA,voltage drops to 270V. I have a feedback circuit but i don't know why it drops that much. it also works great on simulaton. I even changed the frequency but couldn't manage to read stable voltage under load.
