摘要： A switching device of a chopper circuit is interrupted from a switching circuit when the switching device has a breakdown, whereby power source input is directly output without being boosted by chopper operation. A motor controller provided to ECU of an electrically-driven power steering device is equipped with a chopper circuit for carrying out a voltage boosting operation, a detection circuit for detecting a failure of a first switching device TR1 in the chopper circuit, and an interrupting relay switch. A controller carries out ON/OFF control on the first switching device, and when the detection circuit detects the failure of the switching device, the controller turns off the interrupting relay switch, and separates the first switching device from the chopper circuit. At this time, the battery voltage Vin is output as an output voltage Vout without being boosted by the chopper circuit.

摘要： Current correction control is carried out by control process of a control circuit 13 that temperatures of the electromagnetic relays 18a and 18b are assessed one by one based on the detection temperature by the temperature sensor 18c, when the temperature assessed value rises over the predetermined value, the upper limit of the target current value of the motor 11 is decreased.
