In one embodiment, a system may include multiple transformers each to provide an output to one or more power cells, where the power cells provide AC power to a load. Each transformer may have at least one primary winding and multiple secondary windings, where the primary winding of each transformer is phase shifted with respect to its neighboring transformers and the secondary windings are also phase shifted. The phase shift of the primary winding can be based on the phase shift of the secondary windings and a number of the plurality of transformers.

Modular multi-pulse transformer rectifier for use in symmetric multi-level power converter

In one embodiment, the present invention includes a system having multiple modular transformers each including a primary winding coupled to an input power source and phase-shifted secondary windings each coupled to a power cell. The system further includes different phase output lines coupled to a load. These lines may include first, second and third phase output lines.
