Abstract
A contactless power supply system includes a power transmitter and a power receiver. The power transmitter generates high-frequency power and contactlessly transmits the power to the power receiver. The power transmitter detects reflected power from the power receiver and stops the transmission of the power to the power receiver with reference to the reflected power. The power receiver receives the high-frequency power from the power transmitter and converts the received power into direct current power for charging a power storage device. A switch is operated to electrically connect or disconnect a path to supply the direct current power to the power storage device. The power receiver includes a controller for operating the switch to electrically disconnect the power supply path when the power storage device is in the full charge state.
