In a bridgeless flyback rectifier, two flyback converters operate corresponding to the polarity of the AC input, requiring two transformers. This paper proposes a novel winding structure that realizes zero coupling coefficient between two sets of windings. This enables the integration of two transformers into a single transformer, preventing their flyback operations from interfering with each other. The integrated transformer has approximately 16% lower volume compared to that of conventional transformers. The proposed integrated transformer was built, evaluated, and verified by designing a 75W-bridgeless flyback rectifier with 100kHz switching frequency.本誌: 電気学会論文誌D（産業応用部門誌） Vol.144 No.9 （2024）本誌掲載ページ: 645-653 p原稿種別: 論文／日本語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejias/144/9/144_645/_article/-char/ja/
