摘要： PROBLEM TO BE SOLVED: To prevent voltage from dropping due to a linkage reactor at UPS failures, and suppress inverter capacity from increasing due to lagging load when it is connected, suppress increase in input capacity due to a decrease in the input power factor, and to prevent advance in the input power factor.

At this time, a detector 7 monitors whether the voltage is in the range (reactive power supply range), where it can be compensated for with the reactive power supplied by the inverter 3, based on load current and straightforward voltage detected at (a) and (b). If it is determined as exceeding the reactive power supply range, the UPS 10 switches from parallel power supply to inverter- single power supply by opening the straightforward AC switch 6.
