Abstract
An Uninterruptible Power Supply (UPS) system is provided. The UPS system comprises: an input (102) configured to receive input power having an input voltage level, an output (110) configured to provide output AC power to a load, a converter (104) coupled to the input (102) and configured to convert the input power into DC power having a DC voltage level, a DC bus (106) coupled to the converter (104) and configured to receive the DC power, an inverter (108) coupled to the DC bus (106) and configured to convert the DC power from the DC bus (106) into the output AC power and provide the output AC Power to the output (110), and a controller (114) configured to monitor the input voltage level, monitor a level of the output AC power, and operate the converter (104) to regulate the DC voltage level based on the input voltage level and the output AC power level.
