dc dc isolated forward converter
Thank you for helping. Actually, I choose proper inductance and capacitor for the LC filter. Then I made my simulations for testing the ripple voltage on the load. The problem for me is the circuit must supply 5V DC output with less ripple even it doesn't have any load resistance. I obtain 1A ripple current and proper output with the circuit (39,4uH and 4,16uF ). But without load resistance it is getting really crazy. I also tried different duty cycles for solving this problem to observe that can the feed back control circuit correct this situation. But it doesn't change this. I really don't know what to do.
