摘要：
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 an on-duty of an NPN transistor based on the calculated voltage command value and a DC voltage from a voltage sensor. When the on-duty is influenced by a dead time of NPN transistors, control device fixes the on-duty at 1.0 to control the NPN transistors in such a manner that the voltage is increased or decreased.
