Abstract
An inverter generates transmission power at a prescribed frequency and supplies transmission power to a power transmitter. A power supply ECU is configured to carry out turn-on current control for controlling a turn-on current to a restriction value or less by manipulating a frequency of transmission power by means of the inverter. Turn-on current control includes first processing for determining a direction of manipulation of the frequency for lowering the turn-on current based on a direction of variation in turn-on current at the time when the frequency is varied.
