Abstract: In a first power transmission period, a power transmission device holds, in a memory, a value indicating a frequency f0 corresponding to an actual voltage value that matches a requested voltage value, then causes first AC power to be transmitted by using the frequency f0, and uses a foreign substance detector to determine whether or not a foreign substance is present. When it is determined that no foreign substance is present, in a second power transmission period, the power transmission device causes the power transmission of the first AC power to be resumed by using the value indicating the frequency f0, the value being held in the memory.

Abstract: A wireless power transmission system includes a power control device, a power transmitting device, a relay device, and a power receiving device. The power control device includes a direct-current power supply, and a main control circuit that generates a first load instruction value and a second load instruction value. The power transmitting device returns a first response signal and information on alternating-current power supplied to a load circuit in the relay device, such as a voltage value, when receiving the first load instruction value. The load circuit returns a second response signal when receiving the second load instruction value. The main control circuit determines that not the load circuit but the relay-side power receiving circuit is faulty when not receiving the second response signal within a first period and receiving the first response signal within a second period and not receiving is the information within a second period,
