An adjustment system causes a target power supply device to execute first processing and second processing while causing at least one adjacent power supply device to perform a regular power supply operation. The first processing is processing for measuring a first voltage value while a power supply circuit of the target power supply device does not output an alternating current. The second processing is processing for measuring a second voltage value while the power supply circuit of the target power supply device outputs an alternating current. The adjustment system obtains a feeder circuit reactance of a feeder circuit based on the difference between the first voltage value and the second value, and executes adjustment processing for adjusting circuit characteristics with use of an adjustment unit in accordance with the obtained feeder circuit reactance in such a manner that the feeder circuit impedance is a predetermined impedance.

A power feeding station according to one or more embodiments may include a feeder including a feeder coil that feeds power to a receiver in an electric mobility vehicle, a power supply circuit that supplies AC power to the feeder coil, and a control circuit that controls a frequency and a voltage of the AC power. The control circuit provides, through a notification source a notification of guidance about a stop position of the electric mobility vehicle relative to a housing to increase power transmission efficiency from the feeder to the receiver in accordance with the frequency of the AC power supplied to the feeder coil with which the receiver outputs a constant voltage or in accordance with the voltage of the AC power supplied to the feeder coil with which the receiver outputs a constant and predetermined voltage.
