PROBLEM TO BE SOLVED: To make an optimum frequency at which a current flowing through a power transmission coil is minimized be securely included in a predetermined frequency band in which a frequency of transmission power is adjustable.SOLUTION: Inductance L2 of a power reception coil 312 is set to be between first and second values. Each of the first and second values is calculated using a predetermined formula for calculating an optimum frequency at which a current I1 is minimized in predetermined reception power. The first value is calculated from the formula, when the optimum frequency is the maximum frequency of a predetermined frequency band and load impedance RL is made to be the maximum value in a control range of reception power. The second value is calculated from the formula, when the optimum frequency is the minimum frequency of the predetermined frequency band and the load impedance RL is made to be the minimum value in the control range of reception power.SELECTED DRAWING: Figure 2

    【課題】送電コイルに流れる電流が最小となる最適周波数が、送電電力の周波数を調整可能な所定の周波数帯に確実に含まれるようにする。【解決手段】受電コイル312のインダクタンスL2は、第1及び第2の値の間に設定される。第1及び第2の値の各々は、所定の受電電力において電流I1が最小となる最適周波数を算出する所定の式を用いて算出される。第1の値は、最適周波数が上記周波数帯の最大周波数であり、かつ、負荷インピーダンスRLを受電電力の制御範囲内における最大値とした場合に、上記の式から算出される。第2の値は、最適周波数が上記周波数帯の最小周波数であり、かつ、負荷インピーダンスRLを受電電力の制御範囲内における最小値とした場合に、上記の式から算出される。【選択図】図2
