Abstract

The invention discloses a high-and-low frequency transformer. The high-and-low frequency transformer comprises a base plate, a shell and an iron core. The iron core is arranged on the base plate, comprises an annular magnet yoke and a stem and is covered with the shell. A stem insertion hole is formed in the top of the shell and corresponds to an inner hole of the annular magnet yoke. A plurality of coils are wound around the outer side of the stem and isolated from one another through insulating tape. The stem wound by the coils is arranged in the stem insertion hole in a penetrating mode. The two end faces of the stem are in butt joint with the inner side wall of the annular magnet yoke. The stem is formed by overlaying NiCuZn nanocrystalline laminated sheets, and the annular magnet yoke is formed by overlaying iron-based amorphous alloy laminated sheets. The high-and-low frequency transformer has the advantages of being small in size, clear in structure, reasonable in material selection, high in magnetic conductivity, good in temperature characteristic, high in reliability and the like. The iron core of the high-and-low frequency transformer is formed by overlaying multiple types of materials and is a soft magnet low in power consumption and resistant to electromagnetic interference. The high-and-low frequency transformer can well overcome defects of an existing product, improve power delivery 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.
