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.

Abstract: A power conversion circuit connected to a three phase alternating current line is controlled in a PWM system. To control an arm corresponding to each phase, first to third carrier wave signals are generated. The first to third carrier wave signals include two signals having phases, respectively, offset by 180 degrees from each other. This allows a zero phase component to less frequently reach a peak value and be accordingly reduced as time averaged. This can reduce a zero phase harmonic component generated from a power supply apparatus.
