Summary:To suppress a turn-on current of an inverter in a non-contact power transmission device by circuit control in a non-contact power receiving device.SOLUTION: A vehicle 2 includes an LC resonance circuit R2, a rectifier circuit 206 that converts AC power received contactlessly by the LC resonance circuit R2 into DC power, a filter circuit F2 configured to change the power receiving inductance between the LC resonance circuit R2 and the rectifier circuit 206, a vehicle ECU 500 that controls a variable inductor 204 included in the filter circuit F2, and a communication device 600 that receives, from the power transmission unit 100, inverter information indicating the magnitude of the turn-on current of the inverter 120 included in the power transmission unit 100. The vehicle ECU 500 is configured such that the larger the turn-ON current indicated by the inverter information, the smaller the power receiving inductance by the variable inductor 204.SELECTED DRAWING: Figure 2 【課題】非接触送電装置におけるインバータのターンON電流を非接触受電装置における回路制御によって抑制する。【解決手段】車両2が、LC共振回路R2と、LC共振回路R2により非接触で受電される交流電力を直流電力に変換する整流回路206と、LC共振回路R2と整流回路206との間の受電インダクタンスを変更可能に構成されるフィルタ回路F2と、フィルタ回路F2に含まれる可変インダクタ204を制御する車両ECU500と、送電ユニット100が備えるインバータ120のターンON電流の大きさを示すインバータ情報を送電ユニット100から受信する通信装置600とを備える。車両ECU500は、インバータ情報によって示されるターンON電流が大きいほど、可変インダクタ204によって受電インダクタンスを小さくするように構成される。【選択図】図2
