Abstract
A power source apparatus including a control unit configured to output a control signal to a switching element to switch a target voltage of an output voltage from a transformer. In a case of increasing the output voltage, the control unit outputs the control signal having a first duty when the target voltage is lower than a first threshold value, and outputs the control signal having a second duty larger than the first duty when the target voltage is switched to a value equal to or higher than the first threshold value. In a case of reducing the output voltage, the control unit outputs the control signal having the second duty when the target voltage is equal to or higher than a second threshold value, and outputs the control signal having the first duty when the target voltage is switched to a value lower than the second threshold value.
