A semiconductor unit is arranged between a motor and an inverter circuit that controls the motor. The semiconductor unit includes a transistor and a controller. The transistor is arranged between the inverter circuit and a positive electrode of a battery that supplies power to the inverter circuit, and controls supplying of power from the battery to the inverter circuit. The controller is connected to a control terminal of the transistor, and controls a control voltage that is a voltage applied to the control terminal. When power starts to be supplied from the battery to the inverter circuit, the controller controls the control voltage to intermittently operate the transistor and also decreases the control voltage, which is applied to the control terminal of the transistor, to be lower than the control voltage at which the transistor is fully activated.
