摘要

This research paper introduces an innovative bidirectional direct current–direct current (DC–DC) converter topology for electric vehicle (EV) applications, addressing critical limitations in existing power conversion systems. The proposed design demonstrates key advancements like a unique inductor-capacitor network configuration enabling continuous current flow on both input and output ports, overcoming the prevalent discontinuity issue in conventional converters, an integrated inrush current suppression mechanism through optimized switching sequences, and a significant reduction in passive component requirements while maintaining high power density. Simulation validation confirms a voltage gain enhancement of 2× compared to standard topologies, with measured peak efficiency reaching 96.2% at rated 180W operation. These improvements collectively contribute to enhanced reliability, reduced system footprint, and improved energy efficiency in Electric Vehicle (EV) power trains, positioning the proposed topology as a competitive solution for next-generation vehicular power conversion systems.
