High-frequency power transformer in primary winding and secondary winding combined structure

Abstract

The invention discloses a high-frequency power transformer in a primary winding and secondary winding combined structure. The transformer comprises an inner framework, a middle framework and an outer framework, wherein inner primary windings are wound on the inner framework; secondary windings are wound on the middle framework; outer primary windings are wound on the outer framework; the middle framework is inserted into the outer framework; and the inner framework is inserted into the middle framework. The transformer has a simple structure and process, low leakage inductance, high safety and high reliability.

Description

[0001] technical field [0002] The invention discloses a high-frequency power transformer, in particular a high-frequency power transformer with a combined primary and secondary winding structure. Background technique [0003] With the gradual improvement of the living standards of consumers, people's demand for various household appliances is also growing continuously. Household appliances have long been an indispensable thing in people's daily life, and even many household appliances have become an integral part of personal property. It is not uncommon to cause injuries to users due to quality defects in household electrical appliances and improper use and operation. than safe. Household appliances are frequently contacted by users, so for the sake of safety, current household appliances generally use high-frequency switching power supply to convert high-voltage AC mains power into safe DC power to power household appliances. Because the high-frequency switching pow...
