Abstract: Provided are a coupled inductor and a power module including the coupled inductor. A coupled inductor includes: a magnetic core, a first winding and a second winding, where a first passage is formed in the magnetic core; a part of the first winding and a part of the second winding pass through the first passage, and the first winding crosses with the second winding outside the first passage. Another coupled inductor includes: a magnetic core, a first winding and a second winding, where the magnetic core has a first passage and a second passage in parallel, both run through the magnetic core from one end face thereof to another opposite end face, where the first winding and the second winding both penetrate the first passage and the second passage, such that differently-named terminals of the windings are located on the same end face of the magnetic core.

Abstract: The present disclosure provides a multi-phase coupled inductor, a multi-phase coupled inductor array and a two-phase inverse coupled inductor. The multi-phase coupled inductor includes a magnetic core having longitudinal middle columns and windings respectively wound around the longitudinal middle columns. A magnetic flux direction of a DC magnetic flux generated by a current flowing through any one of the windings is opposite to a magnetic flux direction of a DC magnetic flux generated by a current flowing through other one of the windings, on the longitudinal middle column corresponding to the other one of the windings.

Abstract: The present disclosure provides a coupled inductor and a power module. The coupled inductor includes a magnetic core, a first winding, a second winding, and an adjustment structure located in the magnetic core. At least part of the first winding and at least part of the second winding are in the magnetic core, a stacked portion of the first winding and a stacked portion of the second winding are stacked in a height direction, a non-stacked portion of the first winding and the second winding are not stacked in the height direction, and a non-stacked portion of the second winding and the first winding are not stacked in the height direction. The adjustment structure which is adjoining the non-stacked portion of the first winding and the non-stacked portion of the second winding and has a lower magnetic permeability than that of the magnetic core may adjusts leakage inductance.

Abstract: A multi-winding inductor includes a magnetic core including four magnetic columns and a winding assembly including two windings. Each winding includes three portions. The first and third portions of the first winding are respectively between the first and the second magnetic columns, and the third and the fourth magnetic columns; and the first and third portions of the second winding are respectively between the fourth and the first magnetic columns, and the second and the third magnetic columns. Both the first portions of two windings extend to a surface of the magnetic core and respectively form a first and a third pins. The winding is a flat wire with the thickness less than the width, and the width direction is parallel to an extension direction of the first magnetic column.
