1. A resonant converter for coupling between a DC circuit and an AC circuit comprising:

  • a resonant circuit having an input to couple to the DC circuit and being coupled to a switch/filter circuit, having an output to couple to the AC circuit, wherein the resonant converter contains a direct connection between a first voltage center in the DC circuit and a second voltage center in the resonant circuit, and wherein the resonant circuit comprises at least one transformer having at least two windings, wherein there is a connection from the at least two windings of the transformer to at least first and second switches, wherein activation of the first and second switches respectively couples the at least two windings to at least a first node, and wherein the first voltage center in the DC circuit is also coupled to the first node by activation of at least a third switch.
