Problems solved by technology

[0002] In the prior art, in the frequency range of 1kHz-100kHz, the range of soft magnetic material cores that can be selected for high-power inductors is small, the size of ferrite cores is too small, the loss of silicon steel cores is relatively large, and the loss of magnetic powder cores is relatively small. The size is small, the magnetic permeability of the material is low, and the loss is also large. When using a bulk amorphous or ultrafine crystal core, the air gap of the core is concentrated, resulting in a large leakage of the magnetic field near the air gap and an increase in the loss of the inductance.

Abstract

The invention discloses a core for a composite induction transformer. The core comprises an upper iron yoke, a lower iron yoke and a middle column, wherein the upper and lower iron yokes are matched; and the middle column is arranged between the upper and lower iron yokes. According to the core for the composite induction transformer, core loss can be reduced, and the efficiency of the induction transformer can be improved.

Description

technical field [0001] The invention relates to the technical field of transformer cores, in particular to a composite inductance transformer core. Background technique [0002] In the prior art, in the frequency range of 1kHz-100kHz, the range of soft magnetic material cores that can be selected for high-power inductors is small, the size of ferrite cores is too small, the loss of silicon steel cores is relatively large, and the loss of magnetic powder cores is relatively small. The size is small, the magnetic permeability of the material is low, and the loss is also large. When using a bulk amorphous or ultrafine crystal core, the air gap of the core is concentrated, resulting in a large leakage of the magnetic field near the air gap and an increase in the loss of the inductance. Contents of the invention [0003] The technical problem mainly solved by the invention is to provide a composite inductance transformer iron core, which can reduce the loss of the magnetic core...
