Multi-Input Integrated Smart Charger-Inverter System with Galvanic Isolation

This project is to develop a 150kW wide-bandgap (WBG) device-based traction inverter with the capability to serve as a charger, eliminating the need for an additional on-board or off-board charger. The charger will be equipped with a unique interface providing the option to charge the vehicle either an AC source (three-phase or single-phase) or a DC source broadening charger accessibility. The overall system will be optimized with an emphasis on minimizing losses, cost, and EMI effects while meeting or exceeding the 7.2kW power transfer capability. The proposed approach and the considered power level will enable a significant cost reduction in the subcompact vehicle segment which is both an entry-level electric vehicle (EV) and at an affordable price. The reduction in cost, availability of different charging options, and increased mileage due to reduced weight will help us reach the goal of electrifying the transportation sector.
