A high-frequency transformador is a special type of high-frequency transformador commonly used in power systems, especially when starting up a buck. So what are the two characteristics of high-frequency transformadors?

1. The primary of the high-frequency transformador shares a set of coils, and the voltage can be raised and lowered with different taps. If there are fewer taps than ordinary coils, this section is used for bucking, otherwise it is used for boosting.

2. Compared with isolated high-frequency transformadors of the same capacity, high-frequency transformadors have the characteristics of small size and light weight, and at the same time greatly reduce their production costs. High-frequency transformadors generally use magnetic cores instead of iron cores. The high-frequency transformador is small in size, with a small number of turns in the primary coil and high efficiency.

A high-frequency transformador, as the name suggests, is a power electronic instrument that changes the voltage. It is a device that uses the principle of Faraday electromagnetic induction to change the AC voltage, mainly composed of a primary coil, an iron core and a secondary coil. It can realize the matching conversion of input and output current, voltage, and impedance, and can also achieve primary physical isolation. According to the different primary voltages, it can be divided into step-down high-frequency transformadors, step-up high-frequency transformadors, isolated high-frequency transformadors, etc
