Abstract: Uninterruptible power supplies, power modules, and non-transitory computer readable mediums storing instructions for operating such power modules, the power modules comprising an input configured to receive AC power from an AC power source, an output configured to provide AC output power to a load, and a plurality of power modules coupled in parallel between the input and the output, each power module of the plurality of power modules configured to provide at least a portion of the AC output power to the output. Each power module of the plurality of power modules comprises a current compensator stage configured to generate a current error signal based on output current of a corresponding power module and a gain adjustment stage configured to adjust the current error signal based on a measurement of the output current and a desired output current of the corresponding power module.

Abstract: An uninterruptable power supply (UPS) is disclosed. The UPS includes an input configured to be coupled to a power source, a backup interface configured to be coupled to a backup power source, a backup interface configured to be coupled to a backup power source and to receive backup power from the backup power source, an output configured to be coupled to a load and to provide output power to the load, a bypass line coupled between the input and the output and configured to provide the input power to the output in a bypass mode of operation, an inverter coupled to the output and configured to provide the output power to the output derived from the input power in an online mode of operation, and a controller. Non-transitory computer readable medium for operating the controller and methods of providing output power to a load from a UPS are also disclosed.
