Title: UNINTERRUPTIBLE POWER SUPPLY SYSTEMS AND METHODS USING INTERCONNECTED POWER ROUTING UNITS
Abstract:
A system includes a plurality of power routing units. Each of the power routing units includes a first AC port, a second AC port, and a static switch configured to couple and decouple the first AC port and the second AC port. Each of the power routing units further includes a DC port and a bidirectional converter circuit coupled between the second AC port and the DC port. The DC ports of the power routing units are coupled in common to a DC bus and the system further includes a control circuit configured to control the power routing units to provide power transfer between at least two of the power routing units via the DC bus.
