Abstract

This paper is concerned with the circuit configuration and control of parallel distributed uninterruptible power supply (UPS) systems. These systems are expected to provide high quality continuous power to critical loads in the face of mains disturbances or failure. This paper discusses the system configuration issues of distributed UPS. These can be classified as online or line-interactive systems. Decentralized control without signal communication is a major requirement for distributed systems. This paper discusses the control issues which need to be addressed before distributed UPS systems can become practical
