Abstract
A power supply ECU is configured to: adjust magnitude of transmission power by adjusting a duty of an output voltage of an inverter; and adjust a frequency of the transmission power by controlling the inverter. The power supply ECU is configured to execute first control and second control. In the first control, the frequency is adjusted such that a loss of the inverter decreases while maintaining the transmission power, when a temperature of the inverter exceeds a limit temperature. In the second control, the transmission power is reduced, when the temperature of the inverter exceeds the limit temperature even if the first control is executed.
