Abstract:
1. A voltage adjusting apparatus, comprising: a low-voltage system comprising, a high-voltage system comprising, an isolating unit isolating electrically the low-voltage system and the high-voltage system; a first communication line transmitting an information signal for the equalizing process between the low-voltage control unit and the equalizing unit through the isolating unit; and a second communication line arranged through the isolating unit between the low-voltage control unit and the high-voltage power supply circuit, wherein the low-voltage control unit transmits a power-off signal through the second communication line to the high-voltage power supply circuit when the information signal from the equalizing unit is not transmitted within a predetermined first malfunction judging period, and controls the high-voltage power supply circuit to be switched power off, wherein the equalizing unit stops the equalizing process therein when the information signal from the low-voltage control unit is not transmitted within a predetermined second malfunction judging period.
