Inversion inductor

Abstract

The invention discloses an inversion inductor, which comprises a magnetic core, and a coil and a coil leading-out terminal wound on the magnetic core, wherein the magnetic core comprises a plate-shaped magnetic core A, a plate-shaped magnetic core B, a column-shaped magnetic core A, and a column-shaped magnetic core B; the plate-shaped magnetic core A and the plate-shaped magnetic core B are arranged in a relatively spacing manner, the column-shaped magnetic core A and the column-shaped magnetic core B are vertically arranged between the plate-shaped magnetic core A and the plate-shaped magnetic core B in a spacing manner, and both ends of the column-shaped magnetic core A and both ends of the column-shaped magnetic core B are respectively in abutment joint with the opposite surfaces of the plate-shaped magnetic core A and the plate-shaped magnetic core B, so that the plate-shaped magnetic core A, the plate-shaped magnetic core B, the column-shaped magnetic core A, and the column-shaped magnetic core B are connected into an integral whole; and the coil is wound on the column-shaped magnetic core A and the column-shaped magnetic core B respectively. By using the inversion inductor disclosed by the invention, the quality factor of the inversion inductor is improved, the material cost of the magnetic core is greatly reduced, noise and heat generation are decreased, and at the same time, the operation of assembly is greatly simplified, thereby being beneficial to improving the production efficiency of the inversion inductor.

Description

technical field [0001] The invention relates to an inverter inductor. Background technique [0002] The inverter inductor is an important part widely used in the inverter, and its performance has a great influence on the overall performance of the inverter. [0003] like Figure 1 to Figure 5 As shown, the magnetic cores of the existing inverter inductors generally use two U-shaped amorphous structure iron cores 11 arranged opposite to each other in the middle, and the two iron cores 11 are bound and fixed with iron bands 14. The straight part of 11 is wound around the coil 13, leading out the coil lead-out 15. Structurally, an air gap 12 must be provided between the opposite ends of the two iron cores 11 to meet the inductance requirement. [0004] The existing inverter inductance has the following defects: [0005] First of all, because there is an air gap 12 in the middle junction of the two magnetic cores of the existing inverter inductor, the magnetic core must be bo...

AI Technical Summary

Problems solved by technology

[0008] Improving the Q value of the inverter inductor has always been the goal pursued by the industry, but it is still not possible to obtain an inverter inductor with a higher Q value

[0009] Secondly, the magnetic core adopts amorphous iron core, which is costly

[0010] In addition, the air gap is set in the middle of the coil, resulting in large inductance noise

The production and assembly of the existing inverter inductor magnetic core structure is difficult, the operation is complicated, and the production efficiency is low
