CONTACTLESS ELECTRICITY-SUPPLYING DEVICE |
摘要 |
There is provided a contactless electricity-supplying device that can safely and efficiently supply power to a load. A contactless electricity-supplying device includes a plurality of electricity-supplying coils; a DC/AC converter that converts an output voltage from a DC supplying unit into an AC voltage to be applied to each electricity-supplying coils; a plurality of electricity-receiving coils selectively and detachably mounted on positions where the electricity-receiving coils are electromagnetically coupled to the electricity-supplying coils to receive AC voltages from the corresponding electricity-supplying coils in a contactless manner; a plurality of rectifying/smooth units that each convert an AC voltage output from each electricity-receiving coil into a DC voltage and smooth the DC voltage; a switching device that connects the DC voltages output from the rectifying/smoothing units to a single load; an electricity-reception detection sensor for detecting that the electricity-receiving coils receive the AC voltages from the corresponding electricity-supplying coils; and a control unit that turns on the switching device when it is detected that all of the electricity-receiving coils receive the AC voltages from the corresponding electricity-supplying coils. |
