In this paper, a novel type auxiliary active edge resonant snubber assisted zero current soft switching pulse modulation series load resonant inverter using IGBT power modules is proposed for cost effective consumer high-frequency induction heating (IH) appliances. Its operating principle in steady state is described by using each switching mode equivalent operating circuits. The new multi resonant...
This paper presents a new circuit topology of dc bus line switch-assisted half-bridge soft switching PWM inverter type dc-dc converter for arc welder. The proposed power converter is composed of typical voltage source half-bridge high frequency PWM inverter with a high frequency transformer link in addition to dc bus line side power semiconductor switching devices for PWM control scheme and capacitive...
This paper presents an innovative prototype of a new conceptual electromagnetic induction heated type far infrared rays radiant heating appliance using the voltage-fed edge-resonant ZVS-PWM high frequency inverter using IGBTs for food cooking and processing which operates under a constant frequency variable power regulation scheme. This power electronic appliance with soft switching high frequency...

This paper deals with a novel type soft switching PWM power frequency AC-AC converter using bidirectional active switches or high frequency PWM controlled cyclo-conversion circuit, which can directly convert utility frequency AC (UFAC, 50 Hz/60 Hz) power to high frequency AC (HFAC) power ranging more than 20 kHz up to 100 kHz. A novel soft switching PWM prototype of high frequency multi-resonant PWM...
