摘要：A motor control circuit includes a power relay, a converter division, a smoothingcondenser, a control circuit and a motor drive circuit, and is connected to a battery ashigh voltage power and to an electrical motor. The battery is connected with a drivingbattery having the high voltage such as 288V etc. A step down circuit reduces the high

voltage to a low voltage such as 36V etc., charges a low voltage charge device andsupplies drive power to the motor drive circuit. When the vehicle collision is occurred, thecontrol circuit detects the collision by a value of detected acceleration, a power changerelay is turned on to change to the power source from the low voltage charge deviceafter voltage of the smoothing condenser is reduced, thereby connecting the lowvoltage to the motor drive circuit.
