| 摘要 |
A three-phase to three-phase AC converter(34) comprises three primary side phase legs (20a, 20b, 20c), three secondary side phase legs (24a, 24b, 24c) and at least nine single-phase AC-to-AC converter cells (26), each converter cell (26) comprising a distinct galvanic isolation. Three converter cells (26) of the nine converter cells (26) are connected in series in each primary side phase leg(20a, 20b, 20c) and three converter cells (26) of the nine converter cells (26) are connected in series in each secondary side phase leg(24a, 24b, 24c), such that three converter cells (26) connected to one primary side phase leg(20a, 20b, 20c) are connected to each of the secondary side phase legs (24a, 24b, 24c). |
