Abstract: A coupled inductor and a power converter includes a magnetic core and at least two windings. The magnetic core includes at least two magnetic cylinders and two opposite magnet yokes. 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.
