Abstract:
1. A transformer assembly comprising: a first lamination assembly having a first shape and defining a passage therethrough; a second lamination assembly having a second shape and configured and dimensioned for being fully embedded within the passage formed in the first lamination assembly; a bobbin defining a central passage configured and dimensioned to selectively receive the second lamination assembly therein, wherein the passage of the first lamination assembly is configured and dimensioned to selectively receive the second lamination assembly and the bobbin therein; at least one face plate overlying substantially a major portion of the front surface of the first lamination assembly and at least a portion of the second lamination assembly, when the second lamination assembly is fully embedded within the passage of the first lamination assembly, for maintaining the second lamination assembly within the passage of the first lamination assembly; wherein the first shape is geometrically different than the second shape; wherein a portion of the second lamination assembly contacts a portion of the passage formed in the first lamination assembly; and at least one conduit passing through the passage of the first lamination assembly and located between the embedded second lamination assembly, the bobbin and the first lamination assembly.
