Abstract

The invention provides an integrated magnetic element and an integrated magnetic element system based on power equipment, and relates to the technical field of magnetic elements, the integrated magnetic element comprises a primary winding coil, a secondary winding coil and at least two magnetic cores; the primary winding coil and the secondary winding coil are respectively wound on different magnetic cores in a sleeving manner; the first winding coupling degree is larger than the second winding coupling degree, the first winding coupling degree is the coupling degree of the primary winding coil and the secondary winding coil located on the outer side of the window of the magnetic core, and the second winding coupling degree is the coupling degree of the primary winding coil and the secondary winding coil located on the inner side of the window of the magnetic core; and the technical problem that the leakage magnetic field is too large is overcome.

Description

technical field [0001] The present application relates to the technical field of magnetic components, in particular to an integrated magnetic component and an integrated magnetic component system based on electric equipment. Background technique [0002] With the development of the electromagnetic field and the increase of energy consumption, in order to achieve low carbon emissions, high efficiency and energy saving, the requirements for the efficiency and power density of power electronic converters are constantly increasing. Usually, the magnetic components in the power electronic converter account for more than 30% of the volume, and the loss can reach 50%. Among them, the inductor and transformer are the main parts of the magnetic components, so they become the main factors that restrict the efficiency and power density of the power electronic converter. one of the factors. Furthermore, the magnetic integration property of the magnetic element can be used to further re...
