doi:10.11985/2022.01.008

Abstract

Abstract:

Bidirectional power converter is the key device to realize vehicle to grid(V2G) technique. Introducing integration technique, a new integrated onboard power converter is proposed by sharing the driving motor and the driving power electronic conversion device. It can feed the battery storage energy into the grid and charge the battery. The integrated converter has singe-phase charging and three-phase charging interface, realizes one charger with many ports, and enhances the compactness of the onboard system. The integrated converters under different charging modes are analyzed, and the control strategies under different charging and discharging modes are given. Finally, the simulation and experimental results are given to verify the feasibility of the multi-port integrated converter.

Key words: V2G(Vehicle to grid), charging/discharging mode, integrated onboard converter
