전류 분할 및 통합 자기 구조를 가지는 새로운 승압형 푸쉬-풀 전력 변환 회로

Abstract

An improved current-fed push-pull PWM converter with integrated magnetics is presented With this improved topology, the design of magnetic elements such as an inductor and a transformer becomes easter than that using the conventional topology, especially when the converter is suffered from an extremely high input current Since this gives twice the voltage conversion ratio compared to the conventional one, it is also suited for the high voltage step-up power conversion process The operation of the proposed converter is thoroughly analyzed Also, the theoretical analysis and expenmental results are taken from the laboratory level prototype.
