PROBLEM TO BE SOLVED: To improve responsiveness of feedback control for adjusting transmission power to power having a target value, in a non-contact power transmission device for transmitting power to a power reception device in a non-contact manner.SOLUTION: A power source ECU 250 controls an inverter 220 on the basis of a detection value of transmission power supplied to a power transmission unit 240. The power source ECU 250 executes feedback control based on a detection value of transmission power so that the transmission power is closer to power having a transmission power target value created on the basis of a power reception situation of a power reception device 20, where control gain of the feedback control when the load impedance of a power transmission device 10 seen from an output side of a power source unit is high is larger than control gain when the load impedance is low.SELECTED DRAWING: Figure 1
【課題】受電装置へ非接触で送電する非接触送電装置において、送電電力を目標値に調整するためのフィードバック制御の応答性を向上させる。【解決手段】電源ＥＣＵ２５０は、送電部２４０へ供給される送電電力の検出値に基づいてインバータ２２０を制御する。電源ＥＣＵ２５０は、受電装置２０の受電状況に基づき生成される送電電力目標値に送電電力が近づくように、送電電力の検出値に基づくフィードバック制御を実行する。ここで、送電装置１０の電源部の出力側からみた負荷インピーダンスが大きいときの上記フィードバック制御の制御ゲインは、負荷インピーダンスが小さいときの制御ゲインよりも大きい。【選択図】図１
