Claim 5:
6. The uninterruptible power supply apparatus according to claim 5, wherein
the second controller includes
a gain generating circuit that outputs the first gain in the first and second modes, and outputs the second gain from when the switch command signal is output to when the third time is measured by the timer,
a reference voltage generating circuit that outputs the first reference voltage in the first and second modes, and outputs the second reference voltage from when the switch command signal is output to when the third time is measured by the timer, and
a voltage detector that detects the terminal-to-terminal voltage of the capacitor, and

the second controller
obtains the first and second feed forward components based on a product of the load current and a gain output from the gain generating circuit, and
obtains the first and second feedback components based on deviation between output voltage from the reference voltage generating circuit and a detected value from the voltage detector.
