PROBLEM TO BE SOLVED: To provide a method for controlling uninterruptible power source equipment using a capacitor which can sufficiently utilize stored energy by increasing the energy which can be radiated by from the capacitor. SOLUTION: The method for controlling the uninterruptible power source equipment using the capacitor comprises the step of raising the voltage of an AC input power source to be input to a rectifier to a higher voltage than the voltage of the AC output power source of an inverter in a unit for connecting the AC input power source to the inverter and the capacitor via the rectifier, that is, raising the voltage up to a withstand voltage of the capacitor or the like. Thus, even if the terminal voltage of the capacitor is lowered due to the radiation of the energy, the voltage of the AC output power source of the inverter is maintained at a fixed level, and the more energy stored in the capacitor is utilized. |
