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.
