Abstract :
This paper discusses the design and realization of a high-efficiency large-capacity uninterruptible power supply (UPS) using bidirectional-switch-based three-level NPC multilevel power converter. The benefits of three-level topology for low voltage circuits are provided as a motivation for its application in UPS systems. As a result, the novel UPS features higher efficiency and effective size/weight reduction and hence aims to contribute to greening IT facilities with up-to-date power electronics technology.
