Abstract
In an uninterruptible power supply system, control sections of three uninterruptible power supply units are connected to one another by communication cables to configure one integrated control unit. The integrated control unit brings three switches into conduction if a bias feeding mode is selected by one arbitrary operation section and brings three switches into conduction if an inverter feeding mode is selected. Therefore, there is no need to separately provide an operation section and a control section for operating and controlling all of the uninterruptible power supply units.
