Abstract
Provided is a drive control device including: a DC voltage source; an inverter configured to switch a switching element, to thereby apply a drive voltage to a rotary electric machine to cause a drive current to flow through the rotary electric machine; and a control unit configured to: control an output voltage of the DC voltage source; and perform control of causing, based on a torque command value for the rotary electric machine, a drive current to flow through the switching element in a first control mode, in which a drive current having a value equal to or smaller than a first current limit value is caused to flow, and a second control mode, in which a drive current having a value larger than the first current limit value is caused to flow.
