Abstract:
1. An electrical inductor assembly comprising: a first core bridge of magnetically permeable material; a second core bridge of magnetically permeable material and located substantially parallel to the first core bridge; a third core bridge of magnetically permeable material and located substantially parallel to the second core bridge; first, second and third legs of magnetically permeable material between the first core bridge and the second core bridge with a transverse gap along each of the first, second and third legs; fourth, fifth and sixth legs of magnetically permeable material, each one between the second core bridge and the third core bridge with a transverse gap along each of the fourth, fifth and sixth legs; and first, second, third, fourth, fifth and sixth electrical coils each wound around a different one of the first, second, third, fourth, fifth and sixth legs, wherein electric currents flowing through the first, second, third, fourth, fifth and sixth electrical coils produce magnetic flux which flows through the second core bridge.
