Abstract: A drive device includes a motor with two sets of motor windings and a control unit. The control unit has a board on which an electronic component related to energization control of the motor windings are mounted, a connector unit, and a cover member that covers control components including the board, and is provided on one side in a axial direction of the motor. The connector unit has two main connectors and at least one sub connector used for connection with an outside, and these openings are provided so as to face a side opposite to the motor. The main connectors are connected with a power supply and a communication network. The sub connector has an opening separate from that of the main connector and is connected to a separate member.

Abstract: A booster is mounted on a vehicle having an idle stop function. The booster boosts an input voltage supplied from a battery, and outputs the boosted input voltage to an in-vehicle device. The booster includes a booster circuit and an output voltage sensor. The booster circuit is a chopper-type, and includes a reactor having one end connected to the battery and a switching element connected between an other end of the reactor and a ground. The output voltage sensor detects an output voltage of the booster circuit.
