基于多绕组变压器的多端口AC-DC PFC变换器的ZVS分析与死区时间选择

This article proposes a circuit-theoretic approach to analyze a multiwinding transformer-based multiport isolated ac–dc power factor correction (PFC) converter, with a focus on soft-switching performance. In isolated converters, the energy stored in the leakage fields of the high-frequency transformer plays a critical role in enabling zero voltage switching (ZVS) by discharging the device output c...
