Abstract
A power source apparatus includes a transformer configured to output a voltage, a feedback unit configured to output a feedback signal based on the voltage output from the transformer, and a driving unit configured to drive the transformer according to a setting signal for setting the output voltage and the feedback signal. Whichever of a voltage of positive polarity and a voltage of negative polarity is output, the feedback unit controls the voltage output according to a value of a difference between the output voltage and a threshold value.
