CONTROL DEVICE FOR VOLTAGE CONVERSION DEVICE, VEHICLE IN WHICH THE SAME IS INSTALLED, AND CONTROL METHOD FOR VOLTAGE CONVERSION DEVICE

In a voltage conversion device (12) of a motor drive control device, switching-control is performed so as to enlarge an output allowable voltage range of the voltage conversion device (12) restricted by a dead time in a switching operation for an upper arm (Q1) and a lower arm (Q2) performing power conversion by a switching operation. Accordingly, restriction in the output voltage from the voltage conversion device (12), caused by the dead time, can be suppressed.
