วงจรคอนเวอร์เตอร์เรโซแนนซ์แบบสองทิศทางด้วยการควบคุมแรงดันแบบปรับดิวตี้ไซเคิลสำหรับกล้องวงจรปิดพลังงานแสงอาทิตย์

Abstract

This paper proposes the bidirectional resonant converter with duty cycle voltage control using for CCTV with solar energy. The converter, designed at 20 kHz for 20 W with 92.85 % of efficiency, is operated at zero voltage switch mode for reducing the losses of converter. The modes of operation divide in two modes for operating bidirectional current. The first part is buck mode which has 5 volt at the output voltage and second is boost mode which has 8 volt at the output voltage. The two operation modes of converter will be discussed in this paper.
