Design and Control of 3-Phase Integrated Charger for Dual-Inverter Drivetrain Electric Vehicles

Long recharge times and scarcity of charging stations are huge deterrents to wide-spread electric vehicle adaptation. Integrated 3-phase chargers mitigate these issues by enabling fast charging, using ubiquitous 3-phase power, and reducing charging station complexity through reemployment of onboard systems. Design and control of a 3-phase integrated charger for dual-inverter systems is presented. The charger offers high power charging along with energy storage balancing and vehicle to grid operation. Simulation results demonstrate system charging at 50kW, energy storage balancing, and vehicle to grid operation.
