Abstract

This paper presents a high-efficiency one stage ZVS-PWM resonant single-ended push-pull (SEPP) high frequency inverter with new PFC functional scheme. This high-frequency resonant power converter with lossless snubbing capacitors which is composed of a passive PFC converter operating at one diode conducting full bridge circuit mode consists of asymmetrical ZVS-PWM high frequency inverter with non-bulky electrolytic capacitor stage for DC boosted voltage smoothing and induction heated load with tuned capacitor, and boost inductor between HFAC side and mid point of. The periodic steady-state operating principle of one stage high frequency series load resonant inverter with lossless capacitor is described by using the switching mode equivalent circuits in addition to the simulated operating voltage and current waveforms. The operating performances of this high-frequency ZVS-PWM resonant inverter with lossless snubbing capacitors are also illustrated on the basis of simulation analysis, which includes its UFAC-to-HFAC power regulation characteristics, soft switching operating range, UFAC side power factor characteristics and line current harmonics characteristics by FFT analysis. In principle, the effectiveness of this UFAC-to-HFAC direct power frequency converter designed for consumer high-frequency III appliances is evaluated and proved on the basis of simulation results.
