Patent ID: 8188709

Claim:
A power transmission control device provided in a power transmitting device of a non-contact power transmission system, the non-contact power transmission system performing non-contact power transmission from the power transmitting device to a power receiving device via a primary coil and a secondary coil that are electromagnetically coupled, the power transmission control device comprising: an operation mode switch terminal that receives an operation mode switch control signal, the operation mode switch control signal switching an automatic mode to a switch mode, the power transmitting device starting normal power transmission in the automatic mode after installation of a power-receiving-side instrument that includes the power receiving device, in an area in which power transmitted via non-contact power transmission can be received, has been automatically detected, the power transmitting device supplying power to a load of the power-receiving-side instrument at the normal power transmission, and the power transmitting device starting the normal power transmission in the switch mode after an operation trigger switch has been turned ON; an operation trigger terminal that receives an operation trigger signal, the operation trigger signal occurring due to an operation of the operation trigger switch; and a power-transmitting-side control circuit that controls power transmission to the power receiving device and changes an operation mode of the power transmitting device based on the operation mode switch control signal.
