High and low frequency transformer

Abstract

A high-low frequency transformer, including a bottom plate, a casing, and an iron core; the bottom plate is provided with an iron core, the iron core includes a ring-shaped yoke and a core column, the casing covers the iron core, and the top of the casing is provided with a core column jack , the stem socket corresponds to the inner hole of the annular yoke, a plurality of coils are wound on the outside of the stem, and adjacent coils are separated by an insulating tape layer, and the stem wound with coils is placed on the In the core column jack, the two ends of the core column are docked with the inner wall of the ring yoke; the core column is made of NiCuZn ferrite nanocrystal laminations, and the ring yoke is made of iron-based amorphous alloy The sheets are laminated. The invention has the advantages of small size, clear structure, reasonable material selection, high magnetic permeability, good temperature characteristics, high reliability and the like. Its iron core is made of superimposed materials, which is a soft magnet with low power consumption and anti-electromagnetic interference. The high and low frequency transformer of the invention can well improve the deficiencies of existing products, improve power transmission efficiency, and reduce energy loss.

Description

technical field [0001] The invention relates to an electronic component, in particular to a high-low frequency transformer. Background technique [0002] High and low frequency transformers can transmit the power of various signals, and have become an important part of modern electronic equipment. High and low frequency transformers have a wide range of applications, some are used to transmit the power of single frequency signals, and some are used to transmit the power of narrow frequency signals and The power of a broadband signal. With the development of switching power supply, it provides a broader development space for high and low frequency transformers. [0003] The iron core of high and low frequency transformers is generally made of silicon steel sheets or ferrite. Although the price is relatively cheap, there are large magnetic circuit losses and magnetic flux leakage, high iron loss, and high heat generation, which affects the scope of use and life.
