Abstract
A multi-phase coupled inductor includes at least three windings between a first plane and a second plane and a magnetic core that includes a first magnetic core, a second magnetic core and at least three magnetic core pillars, the first and second magnetic cores are respectively located at two ends of the windings, the magnetic core pillars connect the first and second magnetic cores and form at least three magnetic core units together with the first and second magnetic cores. The magnetic core units and the windings are arranged correspondingly on a one-to-one basis, the magnetic core units surround the corresponding windings and extend from the first plane to the second plane in a same direction, and projections of the at least three magnetic core units on the first plane enclose at least three enclosed areas which correspond to the windings on a one-to-one basis.
