1. A power converter comprising:

  • a multi-phase transformer;

    a multi-phase input conversion section comprising an active front end (AFE) coupled to the multi-phase transformer, wherein the AFE comprises at least one multi-phase input converter stage and at least one multi-phase diode rectifier converter stages, an input converter stage and a multi-phase diode rectifier converter each having an input side that is coupled to each phase of the multi-phase transformer at a secondary winding for the multi-phase transformer;

    a second multi-phase output section comprising a plurality of H-bridge inverters, wherein the plurality of H-bridge inverters is coupled via a dc link stage to the AFE; and

    a multi-phase machine comprising isolated open windings that are connected to only the H-bridge inverters to provide a regenerative power converter.
