To restrict the sum of feeding powers of multiple power reception devices from exceeding the possible output power of a power transmission circuit in a non-contact power supply system.SOLUTION: Non-contact power supply systems 1000, 1000A, and 1000B comprise: power transmission circuits 110 and 110A that execute the supply of high-frequency AC power with a predetermined operating frequency after receiving power from a system power supply PS; multiple power transmission devices 120, 120A, and 120B that can conduct non-contact power feeding, while being connected in parallel with each other with respect to the power transmission circuit; multiple power reception devices 200 that receive the non-contact power feeding from the power transmission device when positioned in any of power transmission areas where the respective power transmission devices can perform power transmission; and a feeding power restriction unit 400 that controls each power reception device so that the sum of the feeding powers demanded by the multiple power reception devices does not exceed the possible output power. Each power reception device transmits power reception device-side information to the feeding power restriction unit. The feeding power restriction unit controls each power reception device using the power reception device-side information.SELECTED DRAWING: Figure 1
【課題】非接触給電システムにおいて、複数の受電装置による給電電力の合計が、送電回路の出力可能電力を上回ることを抑制する。【解決手段】非接触給電システム1000、1000A、1000Bであって、系統電源PSから電力を供給されて、予め定められた動作周波数の高周波交流電力の供給を実行する送電回路110、110Aと、送電回路に対して互いに並列に接続され、非接触給電可能な複数の送電装置120、120A、120Bと、各送電装置による送電が実行可能である送電エリア内のいずれかに位置するときに、送電装置から非接触で給電を受ける複数の受電装置200と、複数の受電装置から要求される給電電力の合計が出力可能電力を上回らないように、各受電装置を制御する給電電力抑制部400と、を備え、各受電装置は、受電装置側情報を給電電力抑制部に対して送信し、給電電力抑制部は、受電装置側情報を利用して各受電装置を制御する。【選択図】図1
