Transformer school in junior high school physics before, so our software engineers basically know, but if you want to learn the hardware, we also need to know more.
Secondary learned in the low-frequency transformer substantially transformer that everyone knows the configuration, consisting of two mountain-shaped magnetic cores or core plus the bobbin configuration. Two or more coils wound on the bobbin. Decided transformer work in low and high frequencies associated with the core or core. For example, we see electricity transformers, high-voltage lines that go through from above that, particularly large volume, that is, the operating frequency of the alternating current frequency of 50 Hz. Inside the transformer cores on silicon steel, silicon steel cores that can only be used on low-frequency transformer, if used in high-frequency transformer loss, heat large, can not even work.
That high-frequency transformer is What the hell? what's the effect? First, low-frequency transformers and high-frequency transformers look similar, different is not the same as inside the core, the core of the high-frequency transformer which is a ferrite material or the like, more brittle, easily broken, like the ferrite core it is suitable for the child to work in dozens or even a few hundred kilohertz Dian M Hz.
HF transformer is an important feature of small volume high efficiency Dian Dian light weight, and the higher the frequency, the smaller the volume, but the core of the higher operating frequency requirements.
This proved very useful high-frequency transformer, a very common application is our every day use of the charger, the charger is now basically a high-frequency transformer, small size and light weight.
But ultimately, still low-frequency transformers, for example, still in use in some stereo, when we use transformer, have to make clear their operating frequencies, of course, there are many parameters of the transformer, then you can get to know.
