what is a transformer?

Transformer is also a kind of inductance component. It is a component made of electromagnetic induction principle of inductor.

In the circuit, it is represented by the letter "work". The transformer is made use of secondary (primary) and two (secondary) winding loops.

The number (turns) ratio is different to change the voltage ratio or current ratio, so as to realize the transmission and distribution of electric energy or signal.

 how can the transformer be classified?

The transformer can be classified according to its working frequency, usage and core switch.

According to the working frequency, it can be divided into high frequency transformer, intermediate frequency transformer and low frequency transformer, and can be divided into power transformer (including power transformer), audio transformer, pulse transformer, constant voltage transformer, coupling transformer, autotransformer, boost transformer, isolation transformer, transmission transformer, output transformer and so on. A variety of; according to the core (Ci Xin) form, it can be divided into "EI" shaped transformer (or "E" shaped transformer), "C" deformed musical instrument and hill shaped voltage regulator.

What are the main functions of the transformer?

1 buck or boost, a large number of applications is the AC mains buck, this transformer is called the power transformer.

2 signal coupling, in the process of signal coupling can be boosted or step-down, in order to obtain the appropriate output signal.

 3 impedance transformation, in many cases require circuit impedance matching, at this time can use the transformer to complete.
