A motor drive device (100) includes a boost converter (12) boosting a power supply voltage and outputting a boosted voltage; an inverter (14) receiving the boosted voltage from the boost converter (12) and driving a motor (M1); and a controller (30) giving a target value of the boosted voltage to the boost converter (12) and setting one of a rectangular-wave control and a non-rectangular-wave control as a control method of the inverter (14). The controller (30) is capable of selecting from a first operation mode for giving a first boosted target value and designating the non-rectangular-wave control as the control method and a second operation mode for giving a second boosted target value lower than the first boosted target value and designating the rectangular-wave control as the control method, in response to a same predetermined input signal indicating a torque request.
