flyback waveform
Hi, I found a problem while monitoring a flyback design.
There is too much oscillation at the drive winding when the PWM turn on. The drive winding waveform should be similar to the VDS. Considering parasitc components, I didn't expect the oscillation to be so severe.
Currently I'm still trying to find the root cause. I would appreciate if someone could offer some advices.
Thank you very much.
