Zusammenfassung:An uninterruptible power supply (UPS) system (100, 300) is provided. The UPS system includes a plurality of UPSs (102, 104, 106, 108, 302, 304, 306), a ring bus (118, 314, 410, 510) coupled to the UPSs (102, 104, 106, 108, 302, 304, 306), a plurality of chokes (130, 132, 134, 136, 332, 334, 336, 406, 418, 518), and at least one static switch (340, 342, 344, 408) coupled between an associated UPS of the UPSs (102, 104, 106, 108, 302, 304, 306) and the ring bus (118, 314, 410, 510). Each choke (130, 132, 134, 136, 332, 334, 336, 406, 418, 518) electrically couples an associated UPS (102, 104, 106, 108, 302, 304, 306) to the ring bus (118, 314, 410, 510). The static switch (340, 342, 344, 408) is switchable to selectively bypass at least one choke (130, 132, 134, 136, 332, 334, 336, 406, 418, 518).
