This paper describes a quasi-resonant ZVS-PWM high frequency inverter using SITs under fixed frequency mode. It is designed so as to operate at soft switching PWM condition in order to minimize switching losses and electrical dynamic stresses in its switching power devices over wide output power regulation ranges. The operating principle of this inverter and its PWM controlled power regulation procedure are presented for induction heating. Its performances are evaluated and discussed from a practical point of view.
