Abstract
A power supply apparatus mounted in a moving body includes: a pickup coil configured to generate induced electromotive force by an AC current flowing through a feeder line arranged along a moving route of the moving body; a power receiver configured to convert an AC power into a DC power; a capacitor connected to the output side of the power receiver; a circuit protector provided between the power receiver and the capacitor, and an electrical load; and an external power supply connector provided to allow connection of a DC external power supply to a first node between the circuit protector and the electrical load.
Claims4
A power supply apparatus mounted in a moving body and receiving power in a contactless manner from a feeder line arranged along a moving route of the moving body and supplying the power to an electrical load of the moving body,
- the power supply apparatus comprising:
- a pickup coil configured to generate induced electromotive force by an alternating current flowing through the feeder line;
- a power receiver configured to convert an alternating-current power received by the pickup coil into a direct-current power;
- a capacitor connected to a positive electrode and a negative electrode on an output side of the power receiver;
- a first circuit protector provided between (i) the power receiver and the capacitor and (ii) the electrical load;
- and
- an external power supply connector provided to allow connection of a direct-current external power supply to a first node between the first circuit protector and the electrical load.
