<P>PROBLEM TO BE SOLVED: To supply multiple DC loads having different input voltages with a stable voltage. <P>SOLUTION: The DC power supply system includes a DC power generator, a DC wiring system supplying the loads with a power from the DC power generator, and non-contact power-supply receptacles interposed among the DC wiring system and the loads and composed of sockets and plugs. In the DC power supply system, the sockets include DC/AC converters converting DC voltages supplied from the DC wiring system into high-frequency voltages, and primary side coils to which the converted high-frequency voltages are applied. In the DC power supply system, the plugs include secondary coils for electromagnetic couplings with the primary coils and AC/DC converters converting the high-frequency voltages induced in the secondary side coils into the DC voltages and applying the DC voltages to the loads. In the DC power supply system, multiple loads operated at different driving voltages can be supplied with the power by using the corresponding plugs. <P>COPYRIGHT: (C)2011,JPO&INPIT |
