PROBLEM TO BE SOLVED: To achieve improvement of convenience, high reliability, improvement of low power consumption performance, miniaturization and low cost of a non-contact power transmission system. SOLUTION: A power transmission control device 20 provided in a power transmitting device 10 has a power-transmitting-side control circuit 22 for controlling power transmission to a power receiving device 40. The power-transmitting-side control circuit causes the power transmitting device 10 to perform intermittent temporary power transmission, detects a response from the power receiving device 40 that has received the power due to the temporary power transmission to automatically detect installation of a power-receiving-side instrument 510 that has the power receiving device 40 in an area in which power transmitted via non-contact power transmission can be received, and causes the power transmitting device to perform continuous normal power transmission to the power receiving device when the installation of the power-receiving-side instrument has been detected. A foreign object detection process may also be performed in combination. COPYRIGHT: (C)2009,JPO&INPIT |
