A novel soft-switching converter with passive auxiliary resonant commutation is presented in this chapter. Soft-switching of the switch can be achieved by using passive auxiliary resonant network. It is very attractive for high power application where IGBT (insulted gate bipolar transistor) is predominantly used as the power switch. Its operation principle is analyzed through its application to the boost converter. The condition of soft switching and the design considerations is analyzed in detail. The novel soft-switching cell can be also used in other basic dc-dc converter. A 5kW, 20kHz prototype which uses IGBT has been made. The effectiveness of the proposed converter is confirmed by the simulation and experimental results.
