An integrated topology for on-board charger and driven of electric vehicle

摘要

This paper presents an integrated topology for on-board charger and driven of electric vehicle. Aiming at the existing issues of electric vehicle, the topology incorporates a charging circuit and a motor driven circuit to optimize the circuit structure, to reduce the circuit size and body weight, and to improve utilization elements. Consist of a dual-active bridge converter(DAB) and a three-phase full-bridge inverter, the topology has two operating modes, which are shifted by mechanical switches. One is charging mode using constant voltage control after constant current control and the other is driving mode using id = 0 control. Simulation based on Matlab/SIMULINK verifies the correctness and feasibility of the topology.
