一种用于谐振变换的具有可控对称性的交叉合并四端口光伏系统拓扑

This article proposes a simple four-port resonant converter for standalone photovoltaic (PV) systems. Specifically, the new topology combines an isolated resonant LLC converter and two bi-directional buck-boost converters by using only four mosfets on the primary side, and thus, fulfills PV voltage regulation and battery management in a low-cost manner. Then, by properly designing the control sequ...
