A motor-driven compressor includes a three-phase motor including a rotor, a housing, a compression unit, a drive circuit, and a controller. The drive circuit includes u-phase upper and lower arm switching elements, v-phase upper and lower arm switching elements, and w-phase upper and lower arm switching elements. The controller performs a deceleration control in response to the rotor being rotating in a direction opposite to the forward direction. The controller controls the drive circuit in a switching control mode that includes a first mode, in which one or more switching elements of the upper and lower arm switching elements of the three phases are activated while the remaining switching elements are deactivated, and a second mode, which differs from the first mode in a combination of the activated and deactivated switching elements.
