1. A controller comprising:

  • a voltage determination module that determines a desired direct current (DC) bus voltage for a DC bus electrically connected between a power factor correction (PFC) module and an inverter power module that drives a motor,wherein the voltage determination module determines the desired DC bus voltage based on at least one of a torque of the motor and a speed of the motor;

    a bus voltage command module that determines a commanded bus voltage based on the desired DC bus voltage; and

    a PFC control module that controls the PFC module to create a voltage on the DC bus that is based on the commanded bus voltage.
