Abstract
Bidirectional chargers provide plug-in electric vehicles (EV) the ability to not only transfer energy from the grid to the vehicle, but also transfer energy from the vehicle to the grid (V2G). The V2G mode allows power utility companies to offset peak power consumption thus allowing household consumers and industry corporations to save money on their electricity bills. This paper describes the design choices of bidirectional chargers and provides the implementation details for a Three-Level PWM AC-DC based charger. Although the three-level PWM AC-DC design requires a more complex controller than its counterparts, Matlab Simulink simulations show the design provides lower total harmonic distortion (THD) and reduced stress to the charger’s components making it a viable charger design for the electric vehicle industry.
