Abstract:
1. A power reception control device includable in a non-contact power transmission system that performs non-contact power transmission from a power transmission device to a power reception device through a primary coil and a secondary coil, the power reception device supplying power to a first load that is electrically connected to a power reception section of the power reception control device, the power reception control device comprising: the power reception section that converts an induced voltage in the secondary coil into a direct-current voltage, a load modulation section that modulates a second load of the power reception section; and a power-reception-side control circuit that controls an operation of the power reception device, the load modulation section being configured to transmit information from the power reception device to the power transmission device through the secondary coil to the primary coil utilizing load modulation of the second load, and the power-reception-side control circuit being configured to reduce the power supplied from the power reception section to the first load when the power-reception-side control circuit controls the load modulation section to transmit the information from the power reception device to the power transmission device.
