A zero current switching ZCS topology that provides zero current turn off but full load turn on of the main switches is analyzed for switching losses. State space models of a non-punch through insulated gate bipolar transistor and a power p-i-n diode are used to simulate the circuit response. The switching energy is compared to that for hard switching and for an auxiliary resonant commutated pole. A more general analysis of other ZCS circuit topologies and switching strategies is included in an appendix.
