PROBLEM TO BE SOLVED: To perform non-contact power transmission with high efficiency by lowering power transmission loss, while suppressing the radiated emission not to exceed a certain level.SOLUTION: Between a power transmission device 10 and a power reception device 20, power is transmitted in non-contact via a power reception unit 310 and a power transmission unit 320. While a power transmission path passing through filter circuits 200 and 400 is formed of bypass switches 500, 510, 520, 530, coupling coefficient between the power reception unit 310 and power transmission unit 320 is estimated. When the estimated coupling coefficient is higher than a predetermined reference value, the bypass switches 500, 510, 520, 530 are controlled to form a power transmission path passing bypass circuits 205, 405, and bypassing the filter circuits 200, 400.SELECTED DRAWING: Figure 1
【課題】放射エミッションが一定レベルを超えないように抑制しつつ、電力伝送損失を低下して高効率で非接触電力伝送を行う。【解決手段】送電装置１０及び受電装置２０の間では、受電部３１０及び送電部３２０を経由して非接触で電力が伝送される。バイパススイッチ５００，５１０，５２０，５３０によって、フィルタ回路２００及び４００を通過する電力伝送経路が形成されている状態において、受電部３１０及び送電部３２０の間の結合係数が推定される。推定された結合係数が所定の基準値よりも高い場合には、バイパススイッチ５００，５１０，５２０，５３０は、バイパス経路２０５，４０５を通過して、フィルタ回路２００及び４００をバイパスする電力伝送経路を形成するように制御される。【選択図】図１
