Patent ID: 6845020

Claim:
A power converter, comprising: a first power conversion assembly comprising a number of switching transistors and a number of diodes, the switching transistors and the diodes electrically coupled in a first circuit configuration; a second power conversion assembly comprising a number of switching transistors and a number of diodes, the number of switching transistors and the number of diodes in the second power conversion assembly being equal to the number of switching transistors and the number of diodes in the first power conversion assembly, the switching transistors and the diodes electrically coupled in a second circuit configuration, the second circuit configuration being the same as the first circuit configuration; a power bus electrically coupling the first and the second power conversion assemblies; at least one controller coupled to control at least one of the first and the second power conversion assemblies, wherein the first and the second circuit configurations are such that the first and the second power conversion assemblies are each operable as at least two of an AC to DC rectifier, a DC to AC inverter, and a DC to DC converter dependent on a set of control signals provided by the controller to control the operation of the switching transistors; a first contactor assembly electrically coupled between a first interface assembly and the first power conversion assembly; and a second contactor assembly electrically coupled between a second interface assembly and the second power conversion assembly.
