  • Patent number: 10976375
    Abstract: There is implemented an on-board controller including a single ground terminal, which can accurately detect a disconnection fault of a ground wire while avoiding erroneous detection due to a temporary voltage abnormality or current abnormality. A voltage at the positive electrode of a smoothing electrolytic capacitor is monitored. In addition, a current flowing through a shunt resistor is also monitored. Based on the monitored current value, there is calculated a voltage range (voltage threshold) at the positive electrode of the smoothing electrolytic capacitor in the case of disconnection of a ground wire. Thus, it is determined whether the ground wire has been disconnected by comparing the calculated voltage threshold with the monitored positive-side voltage described above.
