Abstract

A power module configured to supply a multi-phase current to a multi-phase load is provided. The power module includes an inverter circuit configured to generate a plurality of phase currents that contribute to the multi-phase current and an output voltage based on a plurality of pulse width modulation (PWM) signals; and a control unit configured to generate the plurality of PWM signals to control a plurality of phases based on space vector modulation and modulate the multi-phase current to generate a voltage space vector that is representative of the output voltage and which rotates through a plurality of PWM sectors of a space vector coordinate system. The control unit is configured to regulate a shifting pattern of the plurality of PWM signals during a zero vector switching period such that the shifting pattern is fixed for all of the plurality of PWM sectors as the voltage space vector rotates therethrough.
