Specifically, the wireless charging power converter includes an AC / DC converter for converting power Psrc supplied from the power network into DC power when AC power is AC power, and a low frequency converter (or LF A converter). The operating frequency may be determined to be, for example, between 80 and 90 kHz.

The power P ₁ output from the wireless charging power converter can again be supplied to the circuit consisting of the transmitting coil L ₁ , the first capacitor C ₁ and the first resistor R ₁ , C ₁ ) may be determined so as to have an element value such that it has an operating frequency suitable for charging together with the transmitting coil L ₁ . Here, the first resistor R ₁ may mean a power loss caused by the transmission coil L ₁ and the first capacitor C ₁ .

Here, the transmitting coil L ₁ may be electromagnetically coupled as defined by the receiving coil L ₂ and the coupling coefficient m to allow power to be transmitted, or power may be induced to the receiving coil L ₂ . Therefore, the meaning of power transmission in the present invention can be used in combination with the meaning that power is induced.

Here, the electric power P ₂ induced or transmitted to the receiving coil may be provided to the electric vehicle electric power converter.

Here, the height measured based on the ground surface may correspond to the above-mentioned term vehicle magnetic ground surface.

The position of the transmission pad 14 in the height direction (defined in the z direction) can be determined to be located between the maximum class and the minimum class supported by the power receiving pad 11. For example, It is possible to determine that the power transmission pad is positioned between 100 and 210 mm on the basis of the power receiving pad 11.

Further, the gap between the center of the power transmission pad 14 and the center of the power receiving pad 11 can be determined so as to be located within the limits of the horizontal and vertical directions (defined in the x and y directions). For example, it can be determined to be located within ± 75 (mm) in the horizontal direction (defined in the x direction) and to be located within ± 100 (mm) in the vertical direction (defined in the y direction).

Here, the relative positions of the power transmission pad 14 and the power reception pad 11 can be varied in accordance with their experimental results, and these values are to be understood as exemplary.
