Problems solved by technology

This gap will inevitably lead to the occurrence of magnetic flux leakage
The phenomenon of flux leakage may cause some eddy current loss to the metal surrounding the inductor, which eventually leads to increased power loss of the equipment containing the inductor

Abstract

An integrated inductor comprises a first winding (C1) and a second winding (C2); a first internal magnetic core in the first winding (C1) and a second internal magnetic core in the second winding (C2); and at least one external magnetic core (M) outside the first winding (C1) and the second winding (C2), used for being connected to end portions of the first and second internal magnetic cores to form a magnetic path, the external magnetic core (M) being formed by multiple sub-magnetic cores joint with each other; the magnetic conductivity of at least one sub-magnetic core of the multiple sub-magnetic cores is greater than the magnetic conductivity of other sub-magnetic cores, and the at least one sub-magnetic core at least covers a part of end surfaces of the first internal magnetic core and the second internal magnetic core. The integrated inductor can alleviate the phenomenon of flux leakage, and can reduce costs of the magnetic cores.

Description

technical field [0001] The invention relates to an inductor, in particular to an integrated inductor with a magnetic core composed of multiple blocks. Background technique [0002] At present, with the continuous introduction of high-efficiency and high-power UPS or inverter equipment, in order to meet market requirements and improve competitive advantages, the design and cost requirements for inductors are also getting higher and higher. As the size of the inductor increases, the size of the magnetic core increases accordingly. However, the manufacturing cost of a monolithic, large-volume magnetic core is very high. Therefore, in the prior art, splicing is usually used to form a large-volume magnetic core by splicing a plurality of relatively small blocks. This magnetic core Often referred to as an integrated inductor. [0003] figure 1 One such integrated inductor is shown in . Such as figure 1 As shown, the integrated inductor includes a first winding C1 and a second...
