'UPS 7000HX Series' of High-Efficiency, Large-Capacity UPS Products Using AT-NPC 3-Level for Data Centers

摘要

In recent years, as ICT expands, the building market exemplified by data centers has focused on environmental performance and economy, and the demands for high efficiency, high reliability, and compactness from power supply equipment are increasing. Fuji Electric developed a large capacity high efficiency UPS, "UPS 7000HX Series" (400 V 500 kVA) to meet these needs. Maximum efficiency is as high as 97% and the installation area is 30% less than conventional models. In addition, the parallel operation provides a stable power supply. To achieve this, we set the power conversion circuit construction to three levels and used a three-level dedicated module equipped with the RB-IGBT that we developed in the switching element.
