Development direction of high frequency electronic transformer

The biggest feature of high frequency electronic transformer is high frequency. From the working principle of transformer, increasing the working frequency can reduce the volume and weight of transformer, that is, realize short and light weight, thus improving the transmission power per unit volume (or weight), that is, high power density. These are the inherent characteristics and direct results of high-frequency electronic transformers, and we cannot simply take high frequency, short and light weight and high power density as the development direction of high-frequency electronic transformers. Isn't it too easy to mention a few slogans of "transformation" and "great guiding significance to the electronic transformer industry"? We should start with a series of problems brought by high frequency to electronic transformers. By solving these problems, improving performance and reducing cost, that is, pursuing the best cost performance, a more detailed development direction is put forward, which may have certain guiding significance for the industry.
