What transformer is best used on the charger

Which of the following types of ring, EI, R, and C power transformers is the best?

They all have their own advantages and disadvantages, and no one has the best, so strictly speaking, which kind of power transformer can do the best. Structurally speaking, the ring type can achieve the least magnetic leakage, 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 most fundamental for power transformers.

In the imported amplifier, the application of the ring type power transformer is still the mainstream, which basically illustrates a problem. The evaluation of the power 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 the ring-type power transformer is easy to magnetically saturated, so why don't you think of ways to make it difficult to magnetically saturate? 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 power transformer can also be very high.

The quality of the power transformer has a great influence on the sound, because the transmission energy of the power 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 power 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 the ring type? The low frequency is fierce, the middle and high frequency is a little weaker, why? Because it transmits faster, but if you change the structure effectively, you can do both the ring type and the EI type very well, so The key is to see how you do it.

But at least for sure, the R-type power 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 structure of the R-type power 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 power transformer usually has a sound and is lacking in aura. The low frequency often has no bounce force and appears to be hard.
