Claim:
1. A power converter comprising: a first transformer; a plurality of power amplifier units coupled to the first transformer, each of the power amplifier units including: a plurality of input contactors each coupled to an input of one of the plurality of power amplifiers and a plurality of output contactors coupled to an output of one of the plurality of power amplifiers via which each of the plurality of power amplifier units is to couple between the first transformer and a load; and a master controller coupled to the plurality of power amplifier units, wherein the master controller is to enable redundancy in the power converter such that the power converter is to operate with at least one of the plurality of power amplifier units being disabled via at least one of the corresponding input contactor and output contactor, each of the plurality of power amplifier units being a modular configurable unit configured to operate in a selected one or more of a regenerative mode, a partial regenerative mode, and a non-regenerative mode.
