Abstract

The application provides an integrated magnetic element device and a converter, which relate to the technical field of magnetic elements, including: primary and secondary windings and a magnetic core; the primary and secondary windings are arranged around the magnetic core, and the primary and secondary windings are used for transformers and The inductance provides the winding; the coupling degree of the primary and secondary windings outside the window of the core is higher than the preset coupling degree; the coupling degree of the primary and secondary windings inside the window of the core is lower than the preset coupling degree, which relieves the magnetic core Outer diffusion MFL is a big technical problem through.

Description

technical field [0001] The present application relates to the technical field of magnetic components, in particular to an integrated magnetic component device and a converter. Background technique [0002] With the development of industry 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. In power electronic converters, the volume of magnetic components usually accounts for more than 30%, and its loss can reach 50%. Among them, inductors and transformers are the main parts of magnetic components, so they become the main factors that restrict the efficiency and power density of power electronic converters. One of the factors is to use the magnetic integration property of the magnetic element to greatly reduce the volume of the magnetic element. [0003] At present, the high magnetic integration throu...
