Abstract

The invention discloses a nanocrystalline high-frequency single-phase transformer. The transformer comprises a magnetic core (1), a low-voltage winding (2), a high-voltage winding (3) and a wiring board (4), wherein the nanocrystalline high-frequency single-phase transformer magnetic core adopts two totally-same C type nanocrystalline rings that are tied by insulating bands with flux density of less than 0.5T; the low-voltage winding adopts multi-strand enamelled stranded wires; the diameters of the enamelled wires are chosen according to magnitude of frequencies so as to control the current density to be less than 4.5A / mm2, and after the enamelled wires are coiled based on layers, vacuum pouring is carried out; the high-voltage winding adopts multi-strand enamelled stranded wires passing through the magnetic core; the outlet wires are led out through a wiring nose and welded to the wiring copper bar on the wiring board (4).

Description

Technical field [0001] The invention belongs to the technical field of electric power and relates to a nanocrystalline high-frequency single-phase transformer. Background technique [0002] In the traditional high frequency transformer design, due to the limitation of the magnetic core material, its operating frequency is relatively low, generally around 20kHz. With the continuous development of power supply technology, the miniaturization, high frequency and high power ratio of power supply systems have become an eternal research direction and development trend. Therefore, researching the use of higher frequency power transformers is a key factor in reducing the size of the power supply system and increasing the power output power ratio. At present, high-frequency transformers made of ferrite materials have the characteristics of high conversion efficiency and small size. However, due to the low saturation magnetic induction of ferrite, large unit iron loss at high frequency, ...
