The present invention relates to an MDPS system to which a duplexing structure is applied which comprises: a first control circuit for controlling a motor included in motor driven power steering (MDPS); and a second control circuit for controlling the motor in case of failure of the first control circuit. The first control circuit comprises: an inverter that converts voltage into alternating current and applies it to the motor; a relay for regulating battery voltage applied to the inverter; and a diode for preventing current from flowing in a reverse direction of the first control circuit due to a counter electromotive force generated by the motor when the motor is controlled through the second control circuit.

    본 발명은 MDPS(Motor Driven Power Steering)에 포함된 모터를 제어하는 제1 제어 회로, 및 제1 제어 회로 고장 시 모터를 제어하는 제2 제어 회로를 포함하는 이중화 구조가 적용된 MDPS 시스템에 관한 것으로서, 제1 제어 회로는, 전압을 교류로 변환하여 모터로 인가하는 인버터, 인버터로 인가되는 배터리 전압을 단속하는 릴레이, 및 제2 제어 회로를 통해 모터의 제어가 이루어지는 경우, 모터에 의해 발생되는 역기전력으로 인해 제1 제어 회로의 역방향으로 전류가 흐르는 것을 방지하는 다이오드를 포함하는 것을 특징으로 한다.
