Transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main functions of the transformer are: voltage conversion, current conversion, impedance transformation, isolation, voltage regulation (magnetic saturation transformer) and so on. To make the circuit stable, choose the right transformer. Here are some questions for the selection of transformers.

Transformers can be divided into: distribution transformers, Power Transformers, fully sealed transformers, combined transformers, dry transformers, oil-immersed transformers, single-phase transformers, electric furnace transformers, rectifier transformers, etc.

To make the circuit stable, choose the right transformer. Here are some questions for the selection of transformers:

First, in the production of transformers, what are the advantages and disadvantages of coil winding and manual winding?

The advantage of the machine-wound transformer is that it is efficient and beautiful in appearance, but the toroidal transformer that winds a small hole is troublesome, and the reliability of the insulation process is not as good as the manual winding. Manual winding can make the leakage magnetic flux of the transformer very small, and it can be adjusted at any time during the winding process for the layout of the coil turns. Therefore, the real Hi-END transformer must be hand-wound, hand-wound. ** Disadvantages are low efficiency and slow speed.

Second, ring type, EI type, R type, C type of power transformers which kind?

They all have their own advantages and disadvantages, and there is no such thing as who they say, so strictly speaking which kind of transformer can do it. Structurally speaking, the ring type can achieve magnetic leakage* small, but the EI type can make the intermediate frequency density better. In terms of magnetic saturation alone, the EI type is stronger than the ring type, but in terms of efficiency, the ring type is superior to the EI type. Nevertheless, the key to the problem is whether you can make the best of their strengths and avoid the shortcomings, and this is the fundamental of doing a good job of transformers.

In the current imported amplifiers, the application of toroidal transformers is still the mainstream, which basically illustrates a problem. The evaluation of the transformer by the enthusiast should be objective and fair. You can't take a bad thing for reference and say it is not good. Some people say that a toroidal transformer is easy to magnetically saturated, so why not try to make it difficult to magnetically saturate it? This can be done by technical means. If you don't have to work hard or simply save money, then it's of course easy to magnetically saturate. In the same way, as long as you carefully produce, the efficiency of the EI-type transformer can also be very high.

The quality of the transformer has a great influence on the sound, because the transmission energy of the transformer is closely related to the iron core and the coil, and the transmission rate plays a decisive role in the influence of the sound. Like the EI type transformer, people usually think that its intermediate frequency is thicker and the high frequency is more slender. Why? Because its transmission speed is relatively slow. And what about the ring? The low frequency is fierce, and the middle and high frequency are slightly weaker. Why? Because it transmits faster, but if you change the structure through an effective structure, you can do both the ring and the EI, so the key is to see how you do it.

But at least for sure, the R-type transformer is not too easy to do. It can also be used to make a small current preamplifier and CD player power supply. If it is used as a power supply for the post amplifier, there are serious defects. Because the structural form of the R-type transformer itself is not easy to change, the ring type and the EI type are relatively easy to change the structure to achieve the humming purpose. The power amplifier power supply made by the R-type transformer usually has a sound that is very tight and lacks aura. The low frequency often has no bounce force and appears to be hard.
