Abstract
Disclosed is a DC/DC converter system that, after calculating required voltages of the first and second motors based on the magnetic flux and speeds of the first and second motors, the voltage supplied to inverters is controlled by a final voltage command determined as a larger value of the battery voltage and the final required voltage. In particular, the final required voltage is determined as a larger value of the required voltages of the first and second motors.
