In addition, the PCS requires an isolated transformer for system safety because of the stray capacitance of PV panels. This paper describes an active power decoupling method using a small-capacity film capacitor. The proposed 3-leg circuit does not require a transformer for isolation, because the input terminal can be connected the output terminal. The experimental results show that twice the grid-frequency components of the input current, which is a power pulsation, is reduced by 91.2%.本誌: 電気学会論文誌D（産業応用部門誌） Vol.141 No.9 （2021）本誌掲載ページ: 747-748 p原稿種別: 研究開発レター／日本語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejias/141/9/141_747/_article/-char/ja/
