Power transmission device, wireless power feeding system, and control method

The present power transmission device performs a power transmission process for transmitting power in a wireless manner through electromagnetic field resonance coupling using a resonance circuit. In a case where a resonance frequency of the resonance circuit set to be the same as a frequency of a power transmission signal which is output as transmission power is deviated during transmission of the power, the present power transmission device detects a direction in which the resonance frequency is deviated and controls the power transmission process on the basis of a detection result thereof. Consequently, it is possible to determine not only whether or not a foreign substance is present in a power transmission region but also determines whether or not the foreign substance influences wireless power transmission with high accuracy, and thus reliability of the wireless power transmission system can be improved.
