What Are the Uses of High Frequency Transformers?

We have now entered the electrical age. Every household is using electricity. At the same time of using electricity, do you think about why the electricity with such a high voltage can be applied to our life? In fact, the most important thing is because there is a high frequency transformers, and today we will talk about the use of high-frequency transformers.

The high-frequency transformer is mainly used in switching power supplies, and it plays an indispensable role. The switching power supplies generally use a half-hour power conversion circuit. These circuits include a high-frequency transformer and a triode. When the circuit is working, the triode turns to the same frequency, thereby generating a high-frequency pulse with a frequency of 100 kHz and then passing through the high-frequency pulse. The frequency transformer performs a step-down, and finally outputs an alternating current with a lower voltage. Of course, the specific voltage value is determined by the number of turns of the main coil in the high-frequency transformer. Generally, an electric appliance will use three transformers, which are called main transformer, drive transformer and auxiliary transformer. Each transformer has its own respective measurement specifications and functions, so these three voltage devices are indispensable.

For the transformer, the core is the core part. The main component of the magnetic material used in the general transformer core is mnzn, but due to the different formulations and production processes, there are many magnetic materials. The number of the magnetic material of each grade will also be different, including the frequency range used, the loss factor, the saturation flux density temperature coefficient, the initial permeability, etc., so it is necessary to choose according to different The purpose of choosing these cores。

The above is all the roles of high-frequency transformers. Here we also know that high-frequency transformers are mainly used in power switches, so we can often see the high-frequency transformers inside the power switch.
