用于混合能源系统的软开关单电感单级多端口双向功率变换器

A soft-switched nonisolated multiport bidirectional converter is proposed for hybrid energy system applications. The proposed topology improves the efficiency and expands the applications of the conventional three-port converter (TPC) by adding a soft-switching cell and a bidirectional power flow path from output to charge the energy storage device. Moreover, soft-switching conditions for all TPC ...
