Abstract
A power supply apparatus includes a resonant circuit that determines a resonant frequency, a drive unit that drives the resonant circuit, and a controller that causes the resonant frequency to change between a first resonant frequency and a second resonant frequency. The first resonant frequency is higher than a frequency of a drive signal of the drive unit and the second resonant frequency is lower than the frequency of the drive signal.
