Title:
DYNAMIC DC LINK VOLTAGE CONTROL
Document Type and Number:
WIPO Patent Application WO/2015/099667
Kind Code:
A8
Abstract:
According to one aspect, embodiments of the invention provide a UPS system comprising an input configured to receive input AC power, an output configured to provide output AC power to a load, a converter coupled to the input and configured to convert the input AC power into DC power, a DC bus configured to receive the DC power, an inverter configured to convert the DC power from the DC bus into output AC power and provide the output AC Power to the output, and a controller configured to receive an output AC output voltage level selection from a user, operate the inverter to generate the output AC power having an AC voltage level based on the output AC output voltage level selection, and operate the converter to generate the DC power having a DC voltage level based on the output AC output voltage level selection.
