A coupled inductor (200) and a power converter are disclosed. The coupled inductor includes a magnetic core and at least two windings (231, 232, ..., and 23n). The magnetic core includes at least two magnetic cylinders (241, 242, ..., and 24n) and two opposite magnet yokes (221, 222), the at least two magnetic cylinders are disposed between the two opposite magnet yokes, the at least two windings are respectively wound around the at least two magnetic cylinders, the at least two windings are in a one-to-one correspondence with the at least two magnetic cylinders, and the at least two windings do not extend out of the two opposite magnet yokes in at least one direction, where each direction of the at least one direction is a direction perpendicular to side faces of the two opposite magnet yokes. The two opposite magnet yokes may be extended in at least one direction, so that the at least two windings do not extend out of the two opposite magnet yokes in the at least one direction, which can reduce cutting of winding coils of the inductor by a leakage magnetic field, thereby reducing an eddy current loss caused by the cutting of the winding coils of the inductor by the leakage magnetic field. |
