Patent ID: 8160654

Claim:
A power reception control device provided in a power reception device of a non-contact power transmission system, the non-contact power transmission system transmitting power from a power transmission device to the power reception device that includes a rectifier circuit and a regulator by electromagnetically coupling a primary coil and a secondary coil, the non-contact power transmission system transmitting an output voltage of the rectifier to the regulator, the regulator transmitting an output voltage of the regulator to a load from a voltage output node of the power reception device, the power reception control device comprising: a power reception control circuit that monitors at least one of a voltage at an input terminal and a voltage at an output terminal of the regulator provided in the power reception device, and, when a capability of supplying power to the load has decreased due to a decrease in at least one of the voltage at the input terminal and the voltage at the output terminal, the power reception control circuit causing a switch circuit provided between the input terminal and the output terminal of the regulator to be turned ON, upon turn on of the switch circuit, the switch circuit forms a bypass path that directly connects the input terminal and the output terminal of the regulator, the output voltage of the rectifier circuit being transmitted to the load through the bypass path.
