ABSTRACT:
A DC--DC converter unit includes a high-voltage circuit having a main fuse provided in a case, a branch circuit branched from the high-voltage circuit on a downstream side of the main fuse, a subfuse inserted in the branch circuit, and a DC-DC converter connected to a terminal of the branch circuit. A main battery, mounted on an electric vehicle, is connected to a primary side of the high-voltage circuit. A high-voltage load is connected to a secondary side of the high-voltage circuit. The circuit of the high-voltage portion can be shortened, so that covered harnesses and waterproof connectors used in the high-voltage portion can be reduced to thereby reduce the cost. Further, the reliability of the high-voltage portion can also be improved.
