N2 - This paper presents a high performance interior permanent magnet (IPM) machine drive using a current source inverter for EV/HEV applications. The constant power operation regions of an IPM machine can be greatly extended due to the voltage-boosting function naturally associated with the CSI and the field weakening techniques. An equivalent circuit model of the IPM machine including the effects of the ac filter capacitors and the motor core-loss resistor is presented, which eliminates the performance deregulation due to the error between the torque producing current of the IPM machine and the current command of the CSI. According to the special requirements of the automotive applications, a novel two-stage control strategy is also proposed to achieve both minimum system losses and high system performance within the whole operating range including the field-weakening region. Simulation results are presented to validate the functionality of the boost mechanism, the effectiveness of the equivalent circuit model and the proposed control scheme.
