Title:
WIRELESS CHARGING SYSTEM AND POWER TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/045058
Kind Code:
A1
Abstract:
The present invention is provided with a power transmission device (10) provided on the ground and a power reception device (20) provided on a vehicle. Power controlled by an inverter circuit (12) is transmitted wirelessly from the power transmission device (10) to the power reception device (20), a power supply command signal at a first frequency (T1) being transmitted wirelessly from the power reception device (20) to the power transmission device (10). The power transmission device (10) has a transmission coil current detection means for detecting a transmission coil current flowing through a transmission coil (13), and controls the voltage outputted to the inverter circuit (12) on the basis of the power supply command signal and the transmission coil current detected by the transmission coil current detection means at a second frequency shorter than the first frequency.
