摘要： A power conversion system (10) includes a first converter (18) effectively connected in series to a second converter (20). Each converter has a plurality of output levels. A phase-shifted transformer (22) is coupled to the converters. The phase-shifted transformer (22) has a delta-wound winding (7) and an open star winding (6). The first converter (18) is coupled to the open star winding (6) and the second converter (20) is coupled to the delta winding (7). The open star winding (6) is configured for direct connection to either of a load (24) or the open star winding of a second phase-shifted transformer, having a delta winding connected to a third converter. One or more DC voltage sources (14, 16) are each connected to the first and second converters (18, 20) by a respective DC link capacitor (30, 32). Each DC voltage source (14, 16) is connected to a common power grid (12) by an isolated multiphase transformer winding (34, 36).
