DIGITALLY CONTROLLED VOLTAGE COMPENSATION SYSTEM FOR ISG VEHICLE

摘要

The present invention relates to a digital-controlled voltage compensation system of an ISG vehicle, which comprises: a digital control unit receiving an ISG signal, an IGN signal, and an ACC input as an input signal, and including a first driver, a second driver, and a switch on/off driver controlled by digital PWM; a bypass switch receiving a battery voltage in a bypass mode and bypassing the same in a normal state under the control of the digital control unit; and a power conversion circuit receiving the battery voltage in an ISG mode and maintaining the output voltage constant under the control of the digital control unit.
