Bidirectional AC-DC Converter Simulation for V2X Power Transmission

Abstract

This paper primarily focuses on the implementation of V2X technology in Electric Vehicles (EV). The pivotal role of power electronics and its control mechanisms is emphasized to enable this technology. We employ a bidirectional totem pole Power Factor Correction (PFC) to convert AC power into DC power, facilitating both the charging and discharging of the EV battery. A detailed exploration of V2X operation and the control intricacies of the AC-DC converter is presented. The converter exhibits a maximum efficiency of 98.5% across various operational modes, with a power factor of 0.995 during charging. Additionally, the paper provides a comparative analysis of different AC-DC converters. Bidirectional PFC plays a pivotal role in aligning with the regulatory mandates and fostering the development of an advancing smart grid ecosystem.
