According to the present invention, provided is a digitally controlled voltage compensation system for an idle stop & go (ISG) vehicle, which comprises: a digital control unit receiving an ISG signal, an IGN signal, and ACC input as an input signal and including a first driver, a second driver, and a switch on/off driver controlled by a digital PWM; a bypass switch receiving battery voltage in a bypass mode to perform bypass in a normal state in accordance with control of the digital control unit; and a power conversion circuit receiving the battery voltage in an ISG mode to maintain constant output voltage in accordance with the control of the digital control unit.
본 발명에 따르면, ISG 신호, IGN 신호, ACC 입력을 입력신호로 받으며, 디지털 PWM으로 제어되는 제 1 드라이버, 제 2 드라이버 및 스위치 온오프 드라이버(switch on/off driver)를 포함하는 디지털 제어부; 상기 디지털 제어부의 제어에 따라서, 바이패스 모드에서 배터리 전압을 입력받아 정상상태에서 바이패스시키기 위한 바이패스 스위치(Sbypass); 및 상기 디지털 제어부의 제어에 따라서, ISG 모드에서 상기 배터리 전압을 입력받아 출력전압을 일정하게 유지하기 위한 전력변환회로;를 포함하는, 디지털 제어 방식의 ISG 차량용 전압 보상 시스템을 제공한다.
