Title:
給電装置および車両給電システム
Document Type and Number:
Japanese Patent JP5211088
Kind Code:
B2
Abstract:
A power feeding device includes a network analyzer that measures measurement of S-parameters of a resonant system that includes an electromagnetic induction coil and a resonance coil, and an electronic control unit (ECU). The ECU adjusts the resonant frequency of the resonance coils to the power supply frequency in accordance with the measured S-parameters. Specifically, the ECU controls variable capacitors to adjust the resonant frequency of resonance coils and, after adjusting the resonant frequency, controls an impedance matching device to match the input impedance of the resonant system with the impedance on a high-frequency power supply device side viewed from the input port of the resonant system.
