Abstract
There provided a power receiving device connectable with a first load circuit operating according to AC power from a power transmitting device in which the power receiver receives the AC power from the power transmitting device via magnetic coupling, the impedance adjuster is capable of converting at least one of voltage and current of the AC power received at the power receiver, the controller controls increase in output voltage of the power transmitting device, the AC power is supplied to the first load circuit via the impedance adjuster when the first load circuit is connected to the power receiving device, and the controller controls the impedance adjuster such that an input impedance of the impedance adjuster is lower than an input impedance of the first load circuit during at least a part of a time period where the output voltage of the power transmitting device is increased.
