Abstract

According to one aspect, embodiments of the invention provide a UPS (100) comprising a plurality of inputs (102a-c), a PFC converter (104) configured to convert 3-phase input power into DC power, an inverter (108) coupled to a positive DC bus (106) and a negative DC bus (107) and configured to convert the DC power received from the positive DC bus (106) and the negative DC bus (107) into output AC power, a first output (110a) configured to provide a first portion of the output AC power from the inverter (108) to a load (111), a second output (110b) configured to provide a second portion of the output AC power from the inverter (108) to the load (111), a third output (110c) configured to be selectively coupled to a neutral line (112) via the inverter (108), and a controller (114) configured to operate the inverter (108) to generate current between the load (111) and the neutral line (112) via the third output (110c) and the inverter (108).
