1. 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, the power receiver comprising a rectifier circuit and a voltage regulator;
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, wherein the power receiver and the capacitor are electrically upstream of the first circuit protector and the electrical load is electrically downstream of the first circuit protector; 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,
wherein the direct-current external power supply is connected to the external power supply connector when the moving body is moved to a position deviated from the moving route and cannot receive the power from the feeder line.
