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