ABSTRACT:
A transformer structure is provided having three cores of laminated magnet material positioned to define two transformer winding carriers. In the preferred embodiment, each core is a pair of C-shaped sections arranged in mouth-to-mouth relationship so as to form pairs of legs joined by connecting portions. A first leg of the first core and a second leg of the second core delimit one of the transformer winding carriers. A third leg of the second core and a fourth leg of the third core delimit the other transformer winding carriers. The winding includes a primary transformer winding having at least a first coil and a second coil, and a secondary transformer winding having at least a first coil and a second coil. The first coils of the primary and second winding are wound along the first transformer winding carrier while the second coils of the primary and secondary transformer windings are wound along the second transformer winding carrier. The primary coils are wound in parallel in such a way that the AC voltage polarity in the two primary coils is 180.degree. out of phase with respect to one another and the AC voltage polarity in the two secondary coils is 180.degree. out of phase with respect to one another.
