Exchange voltage conversion techniques "authentic" electronic transformers

The exchange voltage conversion technique contained in power supply and power electronics techniques is a "genuine" electronic transformer that can also convert low voltage into low voltage for boost conversion.

The important way to convert low voltage into low voltage for step-down transformation is to use power electronics techniques to improve the frequency of energy conversion, thereby reducing the volume of transformers and inductors in the circuit, rather than banning them. Previously, insufficient attention was paid to the combination of power electronic circuits and electronic transformers.

In recent years, with the increasing demand for output and output harmonics in the power system, the demand for improving grid side power factor, and achieving "green transformation" has become increasingly low. Research on "power electronic transformers" has begun both domestically and internationally, leading to the decline of the research and development boom. Study how to use power electronic techniques to transform and master power, and replace traditional electromagnetic distribution transformers with power electronic transformers.

Nowadays, there are various circuit situations such as single-phase transformation and three-phase transformation. This type of power electronic transformer can be used not only in the low-voltage high current power range, but also in the low-voltage or low-voltage low current range, such as some low-voltage power supply generators and low-power voltage regulating power supplies.

There are over 2000 units engaged in the research, development, and production of electronic transformers in China, including public, private, and foreign-funded enterprises. Both the electronic transformer consumer manufacturer Pusi Company in the United States and the soft magnetic ferrite consumer manufacturer TDK Company in Japan have consumer bases in China. Many advanced electronic transformer techniques, consumer processes, and products in the world are gathered together in China. Faced with such a diverse platform, skill exchange is highly promising.
