ABSTRACT:
A control device calculates a voltage command value of a voltage step-up converter based on a torque command value and a motor revolution number and calculates the on-duty of an NPN transistor based on the calculated voltage command value and a DC voltage from a voltage sensor. Under the conditions that the on-duty is influenced by a dead time and the DC voltage is smaller than a predetermined set value, the control device controls NPN transistors to step-up or step-down the voltage while fixing the on-duty at 1.0.
