WIRELESS POWER SUPPLY APPARATUS

A wireless power supply apparatus includes a power transmission resonant circuit, a switching circuit, and a unit-control unit that controls the switching circuit. The unit-control unit performs at least either of a first abnormality determination process for determining whether the wireless power supply apparatus is abnormal using a first detection value detected by a detecting unit in a non-resonant state, and a second abnormality determination process for determining whether the wireless power supply apparatus is abnormal using a second detection value detected by the detecting unit in a resonant state.
