Abstract :The global trend toward electrification is significantly accelerating the adoption of electric vehicles (EVs), making the development of efficient and grid-friendly charging solutions a critical priority. Among these solutions, bidirectional chargers play a vital role in minimizing the impact on the electrical grid by ensuring low total harmonic distortion (THD), a high-power factor (PF), and facilitating vehicle-to-grid (V2G) applications. This paper presents a comparative analysis of two advanced topologies of single-phase totem-pole power factor correction (PFC) converters designed for Level 2 EV chargers, operating at a rated voltage of 230 Vrms and power levels of up to 18 kW. Specifically, this study examines a bidirectional totem-pole converter and a bidirectional interleaved totem-pole converter, assessing their performance based on key metrics such as THD, PF, and efficiency, both in steady-state and transient conditions. The simulation results indicate that both topologies achieve high efficiency and near-unity power factor. However, the interleaved topology exhibits superior performance in minimizing THD and managing high-power conditions while maintaining low current stress on the switches. Nonetheless, this configuration presents a trade-off, resulting in a higher output voltage ripple compared to the standard totem-pole configuration.
