Pulse width modulation (PWM) converters that consist of two or more interleaved boost/buck converter modules are used widely in industry. Soft-switching approaches for these converters can either be zero-voltage switching (ZVS) if implemented with MOSFETs or zero-current switching (ZCS) if implemented with IGBTs. The main idea of this thesis is to implement ZCS for IGBT turn-on and turn-off. Most converters use an auxiliary circuit that is activated whenever a main converter switch is about to be turned off, gradually diverting current away from the switch so that it can turn off with ZCS.
