Abstract
An output power protection apparatus includes a DC conversion unit, an output protection unit, a high-voltage battery, a low-voltage battery, and a control unit. The DC conversion unit converts an input DC power into an output DC power. The output protection unit is connected in series to the DC conversion unit, and the output protection unit has a plurality of protection circuits connected in parallel to each other. When a short-circuit condition occurs between the high-voltage battery and the low-voltage battery or the low-voltage battery is reversely connected in polarity, the control unit generates a control signal to control the protection circuits to disconnect the connection between the low-voltage battery and a low-voltage device, and the DC conversion unit.
