Abstract
Official abstract text for this publication.
A non-contact power supply system is provided with a conversion circuit that converts power of a power transmission-side power supply, and outputs power to a power transmission coil. A power transmission-side controller controls the conversion circuit. A power reception coil receives power from the power transmission coil in a non-contact manner. The power reception coil supplies power to a load electrically connected to the power reception coil. A smoothing circuit smooths power received by the power reception coil. A sensor detects current or voltage in the smoothing circuit. A power reception-side controller acquires a detection value from the sensor. The power transmission-side controller transmits information by controlling the current value or the output time of an output current to the power transmission coil from the conversion circuit. The power reception-side controller receives the information by acquiring an encoded value from the detection value.
