Abstract

A high power quality DC power distribution system for industrial applications is described. The distribution system incorporates uninterruptible power supply (UPS) properties and can supply larger loads than conventional UPSs. Certain high power applications are very sensitive to power quality problems. The scheme described has two rectifier terminals supplying a DC ring bus system capable supplying a large number of parallel inverters. The DC system incorporates energy storage systems to ride through an AC system outage until a backup generator is brought online. The scheme described utilizes superconductors on the DC bus, but the same basic scheme will work with ordinary conductors following some modification of the converter control
