Abstract
A multi-phase coupled inductor can include: an upper E core including a first upper limb, a second upper limb, and a third upper limb; a lower E core including a first lower limb, a second lower limb, and a third lower limb; a first winding to wind the first upper limb and the first lower limb; a second winding to wind the second upper limb and the second lower limb; a third winding to wind the third upper limb and the third lower limb; a fourth winding to wind the first lower limb; and a fifth winding to wind the third lower limb. A first phase current can flow from the first winding to the fifth winding, and a third phase current can flow from the third winding to the fourth winding.
