Single-Stage Single-Switched Rectifier/Regulator with Magnetic Coupled Nondissipative Snubber = 자기 결합 무손실 스너버를 갖는 단일 전력단 단일 스위치 고역률 전원 장치

다국어 초록 (Multilingual Abstract)

This paper presents a new single-stage single-switched forward converter with magnetic coupled nondissipative snubber, which gives the good power factor correction (PFC), low current harmonic distortion, and tight output voltage regulation. The proposed converter features the low switch current and voltage stresses, essential for the design of a single-stage power factor correction converter. The prototype shows that the IEC 1000-3-2 requirements are met satisfactorily with nearly unity power factor. This proposed converter with magnetic coupled nondissipative snubber is particularly suited for power supply applications with low power level.
