This paper presents a voltage source half bridge series load resonant ZCS-PDM high frequency inverter using IGBT power module for the induction-heating roller in copy machines. The steady-state operating principle and unique features of this high frequency inverter with two ZCS-assisted inductive snubbers in series with the active power switch are presented, which can achieve stable zero current soft commutation under pulse density modulated power regulation scheme. The experimental results of cost effective ZCS-PDM inverter treated here are evaluated on basis of computer simulation ones and discussed for the induction-heating roller from a practice point of view
