Abstract
Provided is an inductor winding method and an inductor winding device. The inductor winding method comprises steps of: A. dividing turns of coil of each winding of the inductor into a first winding and a second winding based on a preset ratio; B. winding the first winding on one of multiple magnetic columns, and winding the second winding on another one of the multiple magnetic columns which is different from the magnetic column on which the first winding is wound; and C. performing step A and step B cyclically until all the windings of the inductor are wound. With a coupling inductor having interleaving-wound structure, power frequency magnetic fluxes generated by magnetic lines in magnetic columns counteract one another, thereby solving the problem of high magnetic flux density in a magnetic core while achieving certain leakage inductance.
