摘要

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.
