A zero voltage platform appears on the secondary side of the forward converter, causing large oscillations. What might be the cause? How can I solve it?
I'm working on a forward converter recently, using RCD for excitation reset, and it's basically working normally. However, when the MOS tube is turned on and off, there is a commutation process betwee
