This paper presents a circuit design and control methods of an electric vehicle (EV) battery charger using a traction motor and
inverter. There are various power electronics based components in the EV for example traction motor, inverter, low-voltage dc/dc
converter and on-board charger (OBC). The proposed power circuit integrates the traction inverter and battery charger. The
reconfigured inverter circuit allows fast charging operation by its high power rating components. In addition, the manufacturer can
get extra space and save weight and cost because the conventional OBC is eliminated. The control method for the battery charging
mode is introduced including a novel low order harmonic compensation method. The experimental results are presented to verify
the feasibility and effectiveness of the proposed power circuit and its control strategies.
