Integrated Inductor Modeling and Current Balancing Control for Multi-phase Interleaved Converter

In this paper, based on the advantages of integrated multiphase coupled inductors, the magnetic integration of each phase inductor is modeled and analyzed based on a multi-phase interleaved buck converter. The closed-loop current balancing control is added, and the coupling simulation is simulated and verified by the later experiments using the three simulation softwares of Maxwell 3D, Simplorer, and Matlab, and the ripple results of the integrated inductor are compared with those of general inductors. The correctness of the method is verified.
