一种用于光伏-储能系统接口的非隔离对称双极性输出四端口变换器

A bipolar dc microgrid is desirable as it enhances the system reliability and efficiency. However, the conventional bipolar dc microgrid requires multiple dc-dc converters to feed the power to the load, which leads to large volume and weight and high cost. In this article, a novel four-port converter is proposed to integrate photovoltaic (PV) module and battery to the bipolar dc microgrid system, ...
