Abstract
A power supply apparatus includes a transformer including primary and secondary windings, a first switching element connected to the primary winding in series, a second switching element connected to the primary winding in parallel, a first capacitor connected to the second switching element in series, and connected to the primary winding in parallel together with the second switching element, and a control unit that controls a switching operation by making each of the first and second switching elements conductive or non-conductive. The control unit makes the first and second switching elements conductive alternately to generate an output voltage to be output to a secondary side of the transformer. During a period after stopping generation of the output voltage and before resuming the generation of the output voltage, the control unit performs the switching operation of the second switching element in a state where the first switching element is made non-conductive.
