摘要：

Novel zero-voltage-transition (ZVT) pulse-width-modulation (PWM) multiphase converters are presented, To construct a ZVT multiphase converter in a conventional way, it is necessary to add the auxiliary circuits with as many number of phases, In the proposed converter, only one auxiliary circuit provides the zero-voltage switching (ZVS) for main switches and diodes of all phases, So, the new converters are cost effective and attractive for high-performance and high power-density conversion applications, Operation, features, and characteristics of the two-phase buck converter are illustrated and verified on a 4-kW 100-kHz insulated gate bipolar transistor (IGBT)-based (a MOSFET for the auxiliary switch) experimental circuit.
