Abstract
A UPS system for communications systems. The UPS system comprises an input stage that generates primary and standby AC power signals. The primary and standby AC power signals are passed through an isolation transformer and through an output rectifier to obtain an output DC power signal. A plurality of output inverters are used to generate a plurality of output AC power signals from the output DC power signal. A switch circuit is provided to connect one or more of the output DC power signals to one or more loads of the communications system.
