Toroidal transformer having a high turns ratio

Claim 1

IN A TOROIDAL TRANSFORMER ADAPTED TO HAVE A HIGH TURNS RATIO WITH OPTIMUM COUPLING BETWEEN WINDINGS, THE COMBINATION COMPRISING: A TOROIDAL CORE OF FERRITE MATERIAL AND HAVING AN AXIS, A SINGLE TURN ELECTRICAL WINDING DISPOSED ON SAID CORE, SAID WINDING BEING A UNIFORM ELECTRICALLY CONDUCTIVE COATING ENCLOSING SUBSTANTIALLY ALL SURFACES OF SAID TOROIDAL CORE, SAID COATING HAVING A FIRST SLIT EXTENDING CIRCUMFERENTIALLY AND COAXIALLY AROUND SAID TOROIDAL CORE, SAID COATING HAVING A SECOND SLIT EXTENDING TRANSVERSELY TO SAID FIRST SLIT AND ANNULARLY AROUND SAID TOROIDAL CORE IN A PLANE WHICH EXTENDS LONGITUDINALLY THROUGH SAID AXIS AND INTERSECTING SAID FIRST SLIT, THE INTERSECTION OF SAID SLITS DEFINING FOUR CORNERS OF SAID COATING, AND A PAIR OF ELECTRICAL TERMINAL CONNECTIONS MADE TO DIAGONALLY OPPOSITE CORNERS OF SAID COATING TO PROVIDE A SUBSTANTIALLY UNIFORM ELECTRICAL CURRENT DISTRIBUTION IN SAID WINDING AND AROUND SAID CORE WHEN SAID WINDING IS ENERGIZED.
