Abstract
The present disclosure relates to a coupled inductor component with integrated current balancing transformer comprising: a magnetically permeable core comprising: a base member and a top member, the base member and top member extending in horizontal planes; first (A), second (B), third (C) and fourth (D) legs arranged substantially perpendicular relative to the base and top member and arranged between the base and top members; first and second directly coupled main windings (L1, L2); first and second reversely coupled current-balancing windings (L3, L4) wound around the fourth (D) and third (C) legs, respectively, wherein the first and second current-balancing windings (L3, L4) are serially connected to the first and second directly coupled main windings (L1, L2), the first and second reversely coupled current-balancing windings (L3, L4) forming a current balancing transformer, wherein a first return path of the first current-balancing winding (L3) and a second return path of the second current-balancing winding (L4) are arranged orthogonally to the first main winding (L1) and the second main winding (L2), respectively, or: a first main winding (L1); first and second reversely coupled current-balancing windings (L3, L4) wound around the fourth (D) and third (C) legs, respectively, wherein the first and second current-balancing windings (L3, L4) are serially connected to the first main winding (L1), the first and second reversely coupled current-balancing windings (L3, L4) forming a current balancing transformer, wherein a first return path of the first current-balancing winding (L3) and a second return path of the second current-balancing winding (L4) are arranged orthogonally to the first main winding (L1).
