Abstract
A self-activating fault protection circuit for an electrical charging system for an on-vehicle rechargeable energy storage device that includes a DC-DC boost converter is described. The self-activating fault protection circuit includes, in one embodiment, an electrical connector including a positive cable and a negative cable, high-voltage electric power bus, and a self-activating fault protection circuit including a high-voltage diode. The DC-DC boost converter is electrically connected to the rechargeable energy storage device via the high-voltage electric power bus, and the electrical connector is electrically connected to the DC-DC boost converter via the positive cable and the negative cable. The high-voltage diode is arranged in the negative cable between the electrical connector and the DC-DC boost converter.
