Summary: The increasing focus on renewable energy generation has led to the expansion of distributed generation and localized DC grids worldwide. DC households are becoming a more prevalent and efficient alternative to AC households. A new four-port converter, called the Bipolar Boost Four-Port Converter (BBFPC), is proposed in this article to integrate renewable energy sources, energy storage elements, and a bipolar port capable of bidirectional power flow. The BBFPC has inductively interfaced ports that can handle bidirectional power flow and perform various functions such as maximum power point tracking for solar PV and voltage regulation or power distribution control for the bipolar port.
