Abstract
The power supply apparatus includes a control unit configured to output a pulse signal for driving a switching element, to drive a transformer to output a voltage from a secondary winding of the transformer, and a memory unit configured to store information associating the output voltage with the duty and the frequency of the pulse signal, and the control unit switches the frequency and the duty based on the output voltage and the information stored in the memory unit.
