PROBLEM TO BE SOLVED: To provide a noncontact power transmission system in which even if power transmission units and power-receiving units are different in specifications and coupling coefficient, an electric power can be appropriately supplied from each power-receiving unit to a load.SOLUTION: A noncontact power transmission system C supplies an electric power from a power transmission device A to a power-receiving device B in a noncontact manner. The power transmission device A includes: a high-frequency power supply device 1 operable to output a constant high-frequency current; and power transmission units 21 to 23 each having a series resonance circuit. The power-receiving device B includes power-receiving units 31 to 33 each having a parallel resonance circuit. A power transmission inductor Lt1 (Lt2, Lt3) of the power transmission unit 21 (22, 23) is magnetically coupled with a power-receiving inductor Lr1 (Lr2, Lr3) of the power-receiving unit 31 (32, 33). Each power transmission unit 21 to 23 is connected in series, and each power-receiving unit 31 to 33 is connected in parallel. The method of power transmission from the power transmission unit 21 (22,23) to the power-receiving unit 31 (32,33) is a magnetic field resonance method.SELECTED DRAWING: Figure 2

    【課題】各送電ユニットおよび各受電ユニットの仕様や結合係数が異なっていても、各受電ユニットから負荷に適切に給電することができる非接触電力伝送システムを提供する。【解決手段】送電装置Aから受電装置Bに非接触で電力を供給する非接触電力伝送システムCにおいて、送電装置Aは、一定の高周波電流を出力する高周波電源装置1と、直列共振回路を有する送電ユニット21〜23とを備え、受電装置Bは、並列共振回路を有する受電ユニット31〜33を備えるようにした。送電ユニット21(22,23)の送電コイルLt1(Lt2,Lt3)と、受電ユニット31(32,33)の受電コイルLr1(Lr2,Lr3)とは、磁気的に結合されている。各送電ユニット21〜23は直列接続され、各受電ユニット31〜33は並列接続され、送電ユニット21(22,23)から受電ユニット31(32,33)への送電方式は、磁界共鳴方式である。【選択図】図2
