An electronic high frequency transformer is a transformer used in electronic circuits and electronic equipment. If the scope of the expansion of some, including all electronic circuits and electronic equipment used in transformers, inductors, transformers and other electromagnetic components. The electron is not limited to power electronics (domestic more general term is power electronics), including industrial electronics, electronic information, wireless electronic and micro electronic transformer, although the difference in power transformer, but it is not different from the RF signal transformer, is not limited to "switch power transformer power converter circuit". A power transformer is only one of the electronic transformers.

The most important feature of electronic high frequency transformer is high frequency. From the working principle of transformer, increasing the working frequency can reduce the size and weight of the transformer, which is the realization of short thin, so as to increase the per unit volume (or weight) transmission power, which is of high power density.

These are the inherent characteristics of electronic high frequency transformer itself and the direct results, but not simply high-frequency, short, thin, high power density, as the direction of the development of high-frequency electronic transformers. If you mention a few "change" slogan, you will be able to "the electronic transformer industry has great guiding significance", is not it too easy? It should be from high frequency to high frequency electronic transformer brings a series of problems, to solve these problems, so as to improve the performance and reduce the cost, but also is the pursuit of the best performance price ratio as a starting point, put forward the development direction of detail, it may have a certain guiding significance for the industry.
