Abstract
The present disclosure provides a multi-phase coupled inductor, a multi-phase coupled inductor array and a two-phase inverse coupled inductor. The multi-phase coupled inductor includes a magnetic core having longitudinal middle columns and windings respectively wound around the longitudinal middle columns. A magnetic flux direction of a DC magnetic flux generated by a current flowing through any one of the windings is opposite to a magnetic flux direction of a DC magnetic flux generated by a current flowing through other one of the windings, on the longitudinal middle column corresponding to the other one of the windings.
