초록

기동 돌입전류가 없는 역률개선을 위한 강압형과 승합형이 결합된 형태의 새로운 푸시풀 퀀텀 직렬공진형 정류기를 제안한다. 제안된 정류기의 동적모델링을 개발하여 기동 돌입전류를 제거하는 제어기법을 제안하였으며 컴퓨터 시뮬레이션과 실험을 통하여 제안된 정류기와 제어기법의 유용성을 보였다. 제안된 방식으로 고역률과 넓은 출력진압 범위를 얻었다.

A combined buck and boost push-pull quantum series resonant rectifier(PPQSRR) is newly proposed to achieve a power factor correction without start-up inrush current. Based on the developed dynamic modeling of the proposed rectifier, an inrush current elimination control technique is proposed and the usefullness of the proposed rectifier and control method are verified by computer simulation and experimental results. With the proposed control method, a high power factor and wide range of output voltage can be obtained.
