Abstract
A control unit calculates a motor voltage vector including a corresponding excitation voltage command and a torque voltage command in response to an output request for the motor and changes a first inverter voltage vector and a second inverter voltage vector while maintaining the motor voltage vector obtained to allow distribution of the motor voltage vector at any ratio. The first inverter voltage vector includes a first excitation voltage command and a first torque voltage command associated with an output from the first inverter, and the second inverter voltage vector includes a second excitation voltage command and a second torque voltage command associated with an output from the second inverter.
