Abstract
A power transmission control device provided in a power transmitting device of a non-contact power transmission system includes a driver control circuit that controls a power transmitting driver that drives a primary coil, a load state detection circuit that detects a power-receiving-side load state, and a control circuit that controls the driver control circuit. The control circuit performs a foreign object detection process based on load state detection information from the load state detection circuit after receiving ID authentication information from a power receiving device, and starts normal power transmission to the power receiving device after performing the foreign object detection process.
