Abstract :
Leakage inductance is known to affect power transfer of transformers and coupled inductors, as well as causing voltage spikes across converter switches possibly damaging them. The standard solution is to implement a snubber to reduce these voltage spikes. This paper investigates the effects of leakage inductance as well as snubbing on conducted EMI emissions.
