Abstract:
The power supply apparatus includes a switching element, a voltage output unit configured to generate a DC voltage by a switching operation of the switching element and output the generated DC voltage, a voltage correction unit configured to detect the output voltage and correct the detected voltage, a control unit configured to control operation of the switching element based on the corrected voltage and a threshold voltage, and a voltage increasing unit configured to increase a correction amount by the correction unit based on the operation of the switching element.
