Abstract
We outline the specifications and performance of a 400 Vdc power distribution system with a 400 Vdc output rectifier. In 2008, The NTT-group have began developing a 400 Vdc distribution system for reducing power consumption and the usage of materials, such as copper in power cables [1]. In conjunction with this project, NTT Facilities has developed prototype rectifiers, a prototype voltage compensator used during interruption periods, and a prototype battery charger. These exhibit higher efficiency than conventional ones and also exhibit high output regulation to adapt charge condition required by valve-regulated lead acid batteries for backup.
