A Novel Cost Effective Edge-Resonant Soft-Switching PWM High Frequency Inverter with Reduced Circuit Component

This paper presents a cost effective edge-resonant soft-switching PWM high frequency inverter with minimum circuit components. This inverter can achieve wider soft commutation, simpler circuit configuration, smaller volumetric size, lower cost and wider power regulation range, higher-efficiency as compared to single ended quasi-resonant ZVS-PFM and active voltage clamped quasi-resonant ZVS-PWM inverters. The practical effectiveness of a novel type edge-resonant soft-switching PWM high frequency inverter using IGBT is actually proved for consumer induction heated appliances. Experimental and simulation results are agreed reasonably.
