Claim 0:
1. An N-phase power converter, wherein N is a natural number greater than 3, inputs of each phase of the N-phase power converter are connected in parallel, outputs of each phase of the N-phase power converter are connected in parallel, and the N-phase power 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 of the M inductor subunits comprises i inductors, i is a natural number equal to 2, N>M×i or N=M×i, and the M×i inductors in the integrated inductor unit are respectively coupled to M×i of the N switch units,
wherein the i inductors of the same inductor subunit are inverse-coupled to each other, and a coupling coefficient between the M inductor subunits is less than a coupling coefficient between the i inductors in the same inductor subunit, and
wherein each of the M inductor subunits comprises a first magnetic column, a first winding and a second winding, the first magnetic column has an air gap, the first winding and the second winding are wound around the first magnetic column to form the i inductors in the inductor subunit, wherein i equals to 2, the first magnetic column of the M inductor subunits are arranged in parallel with each other, wherein the integrated inductor unit further comprises at least one decoupling magnetic column, the decoupling magnetic column has no air gap, the decoupling magnetic column does not have winding, the decoupling magnetic column is arranged in parallel with the first magnetic column, and the first magnetic column is coupled to the at least one of the decoupling magnetic column.
