Problems solved by technology
[0003] However, in the traditional three-phase LLC resonant converter, the three resonant inductors and the three transformers each use independent magnetic cores and form independent closed magnetic circuits, which will increase the overall volume and weight of the power system, and the manufacturing of the power system Increased costs
In addition, when the circuit is working, the magnetic cores of the magnetic components of each converter will generate relatively large magnetic losses. Therefore, the multiple magnetic components of the three-phase LLC resonant converter use independent magnetic cores and form independent closed magnetic cores. Under the road, there will be a problem that the traditional power supply system has a large magnetic loss

The present disclosure relates to a magnetic element, a converter, and an inductor. The magnetic element includes: a magnetic core, including first to third winding windows, wherein a first winding window and a second winding window have a first winding window between them. a shared magnetic column, with a second shared magnetic column between the second winding window and the third winding window; and a winding, including first to third windings, wherein the first winding is wound on the first winding window, The second winding is wound on the second winding window, and the third winding is wound on the third winding window, wherein the winding window and the winding are configured to pass the same current through the first winding to the third winding When , the magnetic fluxes generated respectively in the magnetic core units forming the first winding window and the second winding window are added on the first common magnetic column, and the magnetic fluxes generated in the magnetic core units forming the second winding window and the third winding window Magnetic fluxes respectively generated in the core units are summed on the second common magnetic column.
Description
technical field [0001] The present disclosure relates to a magnetic element, a converter, and an inductor, and more particularly, to a magnetic element, a converter, and an inductor with high power density. Background technique [0002] Usually, magnetic components occupy a large proportion of the overall volume and weight of a power system, so how to reduce the volume and weight of magnetic components has become an important research topic to improve the power density of power systems (such as three-phase LLC resonant converters). [0003] However, in the traditional three-phase LLC resonant converter, the three resonant inductors and the three transformers each use independent magnetic cores and form independent closed magnetic circuits, which will increase the overall volume and weight of the power system, and the manufacturing of the power system Increased costs. In addition, when the circuit is working, the magnetic cores of the magnetic components of each converter wi...
