Abstract
Electrical power conversion systems and methods suited for driving electric motors, and related systems such as propulsion systems, and vehicles employing same, are disclosed herein. In an example embodiment, the electrical power conversion system includes a plurality of series coupled inverters, each including respective first and second DC input terminals and also including respective AC output ports by which the inverters can respectively be coupled at least indirectly to motor winding sets. Additionally, the system includes a controller coupled to the inverters and configured to generate control signals that are respectively provided to the inverters. The control signals tend to cause respective AC output powers output from the respective AC output ports to be equal or substantially equal in a manner that tends to result in respective DC link voltage portions applied between the respective DC input terminals of the respective inverters being or becoming equal or substantially equal.
