Abstract
A power-hub for an electric vehicle and operating modes thereof are disclosed herein. The disclosed power-hub is designed to operate in the Vehicle-to Grid (V2G), Grid-to-Vehicle (G2V), Vehicle-to-Home (V2H), and Vehicle-to-Vehicle (V2V) operating modes. When operating in the V2V mode, the power-hub is configured to allow for sending DC power through a conventional AC power port, with all the associated ratings and constraints from the AC design, in order to achieve higher power transfer and efficiency for V2V operation. A digital Hysteretic Current Mode Control (HCMC) scheme is disclosed and the efficiency and loss distribution of four operating modes are disclosed for the power-hub: 1) DC-AC Boundary Conduction Mode (BCM), 2) DC-AC Continuous Conduction Mode (CCM)/BCM hybrid, 3) DC-DC BCM, and 4) DC-DC CCM. A low-frequency commutation scheme is also disclosed that allows for reducing the peak junction temperature.
