Abstract
A picture frame matrix transformer includes a plurality of interdependent magnetic elements arranged end-to-end in a closed pattern configuration and interwired as a matrix transformer having at least one primary and at least secondary windings wherein the end of the winding begins at one end-to-end position between adjacent magnetic elements and ends at another end-to-end position between adjacent magnetic elements. The magnetic elements further comprise N core segments which are interwired with the primary and secondary windings to provide a matrix transformer having both interger and non-interger transformation ratios. Also disclosed is a picture frame matrix transformer configured as an inductor.

A picture frame matrix transformer, comprising:
- a plurality of interdependent magnetic elements;
- at least one plurality winding comprising an electrical conductor;
- each conductor having first and second ends;
- at least one secondary winding comprising an electrical conductor, each conductor having first and second ends;
- each of said plurality of interdependent magnetic elements being arranged end-to-end with an immediately adjacent magnetic element in a closed pattern configuration;
- one of said at least one primary winding and one secondary winding passing at least once through each of said plurality of interdependent magnetic elements, one of said first and second ends of one of said at least one primary and secondary winding ending at an end-to-end position between adjacent magnetic elements where the other of said first and second ends of another of said at least one primary and secondary winding begins;
- each of said plurality of magnetic elements further having at least one turn of the other of at least one primary and secondary windings with the winding being associated one-for-one with said plurality of magnetic elements, one of said first and second ends of said winding associated with one magnetic element ending at the end-to-end position between magnetic elements where one of said first and second ends of a winding associated with an adjacent magnetic elements begins, said ending of one winding and the beginning of an adjacent winding at an end-to-end position between magnetic elements being repeated for each of said end-to-end positions.
