Design and Performance Analysis of Ultra-Wide Bandgap Power Devices-Based EV Fast Charger Using Bi-Directional Power Converters

Résumé

A widespread introduction of electric vehicles would require an advanced enriched fast-charging infrastructure and battery technology. Currently used silicon (Si) based power electronic devices limit their efficiencies, power density, and switching frequency. Designing fast-charging stations using these materials is not suitable due to low breakdown potential, less thermal stability, and less power handling abilities. The research will propose an off-board DC high-power density fast charging infrastructure with grid tie application. The EV station is designed by using ultra-wideband gap (UWBG) material-based power electronic devices to charge the EV vehicles in a few minutes up to an acceptable state of charge. The study will analyze the characteristics of Gallium III oxide (Ga2O3) material power devices by modeling them using SPICE and TCAD software tools. The research presents the Simscape physical modeling of electric vehicle chargers based on Ga2O3 power devices. Design analysis of three-phase bidirectional AC/DC converter and DC/DC isolated full bridge converter is present in this paper. Research implements the unity power factor control to improve the power quality requirements of the power grid. The dual active power control of converters provides a wide range of charging power for a variety of EV batteries. The study will provide high current and reliable rapid charging for currently available and upcoming future electric vehicles.
