Power reception control device, power reception device, non-contact power transmission system, electronic instrument and power reception control method

A power reception control device included in a non-contact power transmission system that performs non-contact power transmission from a power transmission device to the power reception device through a primary coil and a secondary coil, the power reception device supplying power to a first load, the power reception device comprising:

• a 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 that is electrically connected to the power reception section;
• and
• a power-reception-side control circuit that controls an operation of the power reception device,
• the load modulation section transmitting 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,
• the power-reception-side control circuit reducing or stopping 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.
