Patent ID: 7119648

Claim:
A coaxial push-pull transformer comprising a plurality of coaxial push pull modules, the coaxial push-pull modules comprising at least a first magnetic core having a through hole therein, a first tubular secondary windings extending through the through hole in the at least a first magnetic core, the first tubular secondary winding being a first half of a push pull secondary winding, a second tubular secondary windings extending through the through hole in the at least a first magnetic core, the second tubular secondary winding being a second half of a push pull secondary winding, means for terminating the first and second tubular secondary windings for connection to an electrical circuit, means for insulating the first tubular secondary winding from the second tubular secondary winding and for insulating the first and second tubular secondary windings from the at least a first magnetic core, the plurality of coaxial push-pull modules being arranged and disposed so that the first and second tubular secondary windings are aligned from one coaxial push-pull module to the next, a first primary winding passing through the first tubular secondary windings of the plurality of coaxial push pull modules such that the first tubular secondary windings surround the first primary winding coaxially, a second primary winding passing through the second tubular secondary windings of the plurality of coaxial push pull modules such that the second tubular secondary windings surround the second primary winding coaxially, and means for terminating the first and second primary windings for connection to an electrical circuit.
