I am working on buck converter but stuck on at the basic results.
I simulated my circuit in OrCad.
Attaching my circuit diagram and waveforms.
The problem is with the voltage at source of mosfet. Initially, the m source voltage goes down as gate goes down but just after a little time it is keep turning high(with ringing) while gate is still low.
Can some one please explain why this is happning.
I have fabricated this circuit also, same thing happaning . I am attaching those DSO waveforms too.
