Abstract
A system and method for power pooling, the system including a shared power line, a plurality of backup power supplies connected to the shared power line through respective transformers and one or more controllers configured to, for each respective backup power supply, after passage of a different respective predetermined amount of time, determine whether a transformer connected to the backup power supply is energized. In response to the transformer being energized, the controllers synchronize the backup power supply with the transformer and then set a switch positioned between the backup power supply and the transformer to a fully closed state. In response to the transformer not being energized, the controllers transition the switch from a fully open state to the fully closed state according to an inrush current limiting scheme.
