Abstract

In this uninterruptible power supply apparatus, respective phase differences between first to third carrier wave signals (CSto CS) for a converter () and fourth to sixth carrier wave signals (CSto CS) for an inverter () are set to 180 degrees in an inverter power feed mode and a bypass power feed mode, and respective phase differences between the first to third carrier wave signals and the fourth to sixth carrier wave signals are set to 0 degree in an overlap power feed mode. Zero-phase current (I, I) and circulating current (ICL) therefore can be reduced.
