Power converter, inductor element and control method of phase shedding

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 subunit comprises i inductors, i is a natural number greater than or 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.
