Abstract

The authors describe a continuous supply unit using 40 kVA PWM (pulse-width modulation) inverters, which has been designed to provide variable output power, up to 200 kVA, for the processing systems in telecommunication networks. The system configuration includes at least one and up to 5+1 parallel rectifiers, at least one and up to 5+1 parallel inverters, battery, DC power switchboard system, and AC continuity switchboard. Two important characteristics of the system-in addition to its high reliability, maintainability, operability, and excellent dynamic and static performances-are its capacity for extension without interruption to the user supply, and the presence of a safety device that prevents return of power towards the emergency network in the event of failure
