Claim 0:
1. A power supply circuit for supplying power from a first power source and a second power source to a first load, wherein the first power source and the second power source are in a parallel configuration, wherein the load includes a capacitor that needs to be charged before activation, the power supply circuit comprising:
a first circuit configured to supply power from the first power source to the load and from the second power source to the load; and
a second circuit configured to supply power from the first power source to the load and from the second power source to the load;
wherein:
the first circuit and the second circuit are provided in parallel with each other;
only one of either the first circuit or the second circuit is provided with a precharge circuit configured to charge the capacitor;
when charging the capacitor, power is supplied from the first power source and the second power source to the load via a circuit that is provided with the precharge circuit provided to only one of the first circuit and the second circuit; and
after charging of the capacitor is completed, power is supplied from the first power source and the second power source to the load via a circuit that is not provided with the precharge circuit provided to only one of the first circuit and the second circuit.
