Abstract
An N-phase power converter has N phases with outputs connected in parallel and outputs connected in parallel. The converter comprises: N switch units, wherein each phase of the N-phase power converter comprises one of the N switch units; and an integrated inductor unit, comprising M inductor subunits, wherein M is a natural number greater than or equal to 2, each inductor subunit comprises i inductors, i is a natural number greater than or equal to 2, N>M×i or N=M×i, M×i of the inductors in the integrated inductor unit are respectively coupled to M×i of the N switch units, wherein: the i inductors of each of the inductor subunit are inverse-coupled to each other, the coupling coefficient between the M inductor subunits is less than the coupling coefficient between the i inductors in each of the inductor subunits.
