Abstract
According to one aspect, embodiments of the invention provide a UPS comprising a plurality of inputs, a PFC converter configured to convert 3-phase input power into DC power, an inverter coupled to a positive DC bus and a negative DC bus and configured to convert the DC power received from the positive DC bus and the negative DC bus into output AC power, a first output configured to provide a first portion of the output AC power from the inverter to a load, a second output configured to provide a second portion of the output AC power from the inverter to the load, a third output configured to be selectively coupled to a neutral line via the inverter, and a controller configured to operate the inverter to generate current between the load and the neutral line via the third output and the inverter.
