Zusammenfassung:A system (300) is provided. The system includes a ring bus (306), at least one voltage source (303), and a plurality of uninterruptible power supplies (UPSs) (302) electrically coupled between the at least one voltage source (303) and the ring bus (306), wherein at least one UPS of the plurality of UPSs includes an input, an output, a rectifier (332) having a rectifier input and a rectifier output, an inverter (330) having an inverter input and an inverter output, wherein the rectifier output is electrically coupled to the inverter input, and a bypass switch electrically coupled between the rectifier input and the inverter output, the bypass switch configured to close in response to detection of a fault on the ring bus (306).
