Abstract
A power supply ECU is configured to carry out extreme value search control for searching for a frequency at which a detected value of power loss is minimized, by oscillating a frequency of output power from an inverter. Then, the power supply ECU determines whether or not extreme value search in extreme value search control is poorly proceeding, and when extreme value search is poorly proceeding, the power supply ECU increases an amplitude of frequency oscillation of output power from the inverter.
