A High Performance ZVT-PWM Boost Rectifier with Soft Switched Auxiliary Switch

스프트 스위칭 보조 스위치를 가지는 ZVT-PWM 부스트 컨버터

This paper presents a soft-switching average current control PWM high power factor boost converter. Conventional boost ZVT-PWM converter has a disadvantage of hard-switching for auxiliary switch at turn-off. A soft switched auxiliary switch is proposed to achieve a high performance ZVT-PWM boost rectifier. The simulation and experimental results show that soft switching operation can be maintained for wide line and load range, which in turn improves the converter performance in terms of efficiency, switching noise and circuit reliability.
