Abstract
Various embodiments include an inductor assembly for a converter comprising: a plurality of first conductors arranged on respective legs of a first magnetic core; a second magnetic core with one or more legs, the second core magnetically coupled to the first core via an air-gap and arranged to provide a path for common mode magnetic flux of the plulrality of first conductors; and a respective second conductor corresponding to each of the plurality of first conductors. Each pair of first and second conductors is electrically connected in series. The second conductors are arranged on a single leg of the second core and positively coupled to each other.
