A high-efficiency multi-port bidirectional converter for renewable energy and hybrid electric vehicle applications

The growing demand for electrification and the integration of renewable energy sources necessitate advanced power conversion technologies that combine efficiency and versatility. This paper introduces a novel Multi-Port Bidirectional Converter (MBPC) designed for both grid and hybrid electric vehicle (HEV) applications. Featuring two input and two output ports, the MBPC achieves an efficiency exceeding 95% and a power density above 10 W/cm². It effectively manages energy from sources with varying current and voltage profiles, supporting both boost DC-AC and boost DC-DC operations. The innovative design incorporates a streamlined control strategy and a reduced component count, cutting manufacturing costs by up to 30% compared to traditional converters. The proposed MBPC demonstrates significant potential for advancing power electronics in renewable energy systems and electric vehicles, offering a versatile, efficient, and cost-effective solution for energy storage, motor control, and power management applications.
