Abstract
Some embodiments of the inventive subject matter provide methods of operating an uninterruptible power supply (UPS) configured to provide power to a load from first and second power sources, e.g., from a utility source and a battery or other backup source. The methods include operating the UPS to momentarily provide an altered voltage waveform in coordination with a transition of the load between first and second power sources. For example, the altered voltage waveform may provide a momentarily increased voltage rate of change to compensate for a transient current demand presented by the load.
