Document Type and Number:
Japanese Patent JP6665392
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a non-contact power transmission system capable of suppressing that an electric power to be received is largely changed depending on a received electric power position on parallel two lines.SOLUTION: A non-contact power transmission system 1A comprises a power transmission unit 22 in which a power transmission device 2 includes parallel two lines in which two conductive lines 22a and 22b are provided in parallel; and a high-frequency electric power device 21 that supplies a high-frequency electric power to the power transmission unit 22. A power reception device 3 comprises: a first power reception unit 31 that includes a magnetic field antenna 31a magnetically coupled to the parallel two lines, a resonance capacitor 31b, and a rectification filter circuit 31c; a second power reception unit 32 that includes electric field antennas 32a and 32b electrically coupled to the parallel two lines, a resonance coil 32c, and a rectification filter circuit 32d; and a synthesis part that synthesizes a DC electric power outputted by the first power reception unit 31 and the DC power outputted by the second power reception unit 32, and supplies to a load 4.SELECTED DRAWING: Figure 1
