Abstract
Provided is a power supply unit that includes a switching section and a controller. The switching section is configured to perform a switching operation and thereby generate, based on an input signal, a first alternating-current signal. The controller is configured to control the switching operation and thereby perform an amplitude control that involves increasing, based on an input current in the switching section, a signal amplitude of the first alternating-current signal.
