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.
