Hi,
Currently, I'm learning the two switch flyback topology. I wish to know during the DCM mode, what is the voltage on each mosfet?
Diodes can clamp drain-source voltages of both transistors to the input voltage and the voltage rating of the transistors can be selected according to input voltage. So when we choose a transistor, do we need to leave a bigger margin than the input voltage?
The third question is that since the leakage energy is returned to the input supply via two diodes, is it stored in the input capacitance? Then when we choose the input capacitance, what do we need to pay attention to? Does the leakage energy result to a big ripple?
