A power supply apparatus which stabilizes the output by feeding it back is provided which suppresses variations of the output for abrupt variations of the input. The power supply apparatus comprises output sensing means for sensing output current and output voltage, first output control means for controlling the output with the increment or decrement of the value obtained from said output sensing means, second output control means for controlling the output from an absolute value of the input voltage, and selection means for selecting either said first output control means or said second output control means. The power supply apparatus further comprises means for detecting the variation rate of the input voltage, first monitor means for monitoring the difference between the output value of said output sensing means and the reference value, and second monitor means for monitoring both the difference between the output value of said output sensing means and a reference value, and the input voltage variation rate.
