    Re: What does this circuit do in the Push pull convertor

    Hi,

    I assume this is not the complete circuit ... not enough to answer your questions.

    Also some informations are missing like: waveform, voltage...

    *****
    I recommend to use some simulation software like LTspice.

    Hi,

    voltage = 24 V
    Waveform = Square
    Pulse width = 15% - 25%

    I believe it is a turn off snubber.

    Definitively a snubber.

    I think if its a snubber you need something to discharge those capacitors.

    Re: What does this circuit do in the Push pull convertor

    The capacitors are discharged by the RCD circuit, a bit unusual however.
