Abstract
이 발명은 파워 써플라이의 싱글 소프트 스위칭회로에 관한 것으로 특히, 기존의 파워 써플라이 스위칭 회로에 설치되어 있는 메인 스위칭 소자(Q1)의 양단 사이에는 직렬 연결된 콘덴서(C1)와 다이오드(D1)를 병렬로 연결하고, 상기 다이오드(D1)의 양단에는 코일(L1)을 병렬 연결한 것만으로 소프트 스위칭회로를 형성시킴으로써, 제품의 생산원가를 대폭 절감시킬 수 있음은 물론 파워 써플라이의 효율을 더욱더 향상시킬 수 있는 등 매우 유용한 발명인 것이다.The present invention relates to a single soft switching circuit of a power supply. In particular, a series connected capacitor C1 and a diode D1 are connected in parallel between both ends of the main switching element Q1 installed in a conventional power supply switching circuit. In addition, by forming a soft switching circuit at both ends of the diode D1 by simply connecting the coils L1 in parallel, the production cost of the product can be greatly reduced and the efficiency of the power supply can be further improved. It is a very useful invention.
