This paper introduces an auxiliary motor drive solution based on three-phase onboard battery charger to improve drive capability. The specific scheme of the control strategy is given by circuit analysis and modeling. The proposed scheme reduces the current stress on the driving inverter, increases the total converter output current, achieves fault tolerance, and improves the dynamic response performance based on mathematical model analysis. Besides, the improvements need few additional components, so that the cost is quite low. The above functions have been verified by experiments or simulations.
