POWER SUPPLY SYSTEM, AND POWER SUPPLY METHOD

To simultaneously supply power to multiple power receiving devices in simple configuration.SOLUTION: A power supply system 100 is configured to supply power from a power supplying device 1 to a power receiving device 2. The power supplying device 1 comprises: a power supplying coil 11 that is a winding coil; a drive transistor; and a drive control part which controls whether to continuously supply a driving signal to a drive transistor 13. The power receiving device 2 comprises: a power receiving coil 21 which includes a magnetic core and to which power is supplied from the power supplying coil 11; a resonance circuit including a resonance capacitor which is resonated with the power receiving coil 21, and a resonance control transistor; and a resonance control part which controls the resonance control transistor. The power supplying coil 11 and the power receiving coil 21 are disposed in such a manner that a central axis C1 of the power supplying coil 11 becomes orthogonal with a central axis C2 of the power receiving coil 21 and that a winding portion 211 of the power receiving coil 21 does not enter a region of a magnetic flux, that is generated by the power supplying coil 11, in parallel with the central axis C1 of the power supplying coil 11.SELECTED DRAWING: Figure 1 【課題】簡易な構成により、複数の受電装置に対して、同時に給電する。【解決手段】給電システム１００は、給電装置１から受電装置２に給電する。給電装置１は、巻線コイルである給電コイル１１と、駆動トランジスタと、駆動トランジスタ１３に駆動信号を継続して供給するか否かの制御を行う駆動制御部と、を備え、受電装置２は、磁心を有し、給電コイル１１から給電される受電コイル２１と、受電コイル２１と共振する共振コンデンサ及ぶ共振制御トランジスタを有する共振回路と、共振制御トランジスタを制御する共振制御部と、を備え、給電コイル１１と受電コイル２１とは、給電コイル１１の中心軸Ｃ１と、受電コイル２１の中心軸Ｃ２とが直交し、且つ、受電コイル２１の巻線部分２１１が、給電コイル１１が発生させた給電コイル１１の中心軸Ｃ１と平行な磁束の領域内に入らないように配置される。【選択図】図１
