Abstract
Uninterruptible Power Supply (UPS) Systans are extensively used by modern society for electrical support of computers, communications and other critical systems. Over the last few years, power transistorized UPS´s have become much more practical and their numbers have increased accordingly. The performance of these transistorized UPS´s has been further improved since they were described two years ago [1]. The inverter has been refined and simplified to the extent that the system now contains only one output transformer. The control circuitry now consists of a single circuit board. The improved rectifier has reduced input current distortion significantly.
