Important Factors In Transformer Selection

How to Choose the Right Transformer

First, the production of the toroidal transformers , the coil of the machine around the system and hand-wound system What are the advantages and disadvantages?

Machine winding transformer has the advantage of high efficiency and the appearance of beautiful shape, but the lofty loops around the toroidal transformer is too much trouble, but also in the reliability of the insulation treatment process than hand-wound in place. Manual winding system can be very small magnetic flux leakage, the winding process in the coil turns for the layout of the time to be adjusted, so the real Hi-END transformer must be purely hand-wound, purely hand-wound system The only drawback is the low efficiency, slow.

Second, the toroidal, EI-type, R-type, C-type power transformer of toroidal transformers manufacturer ,which is the best?

They have their own advantages and disadvantages which do not exist who said the best, so strictly speaking which kind of transformer can do the best. From the structural point of view, the ring can be the smallest magnetic flux leakage, but the sound sense of hearing EI type can do a little better sense of the density of the frequency. In terms of magnetic saturation, the EI type is stronger than the ring type, but the efficiency is superior to the EI type. Nevertheless, the crux of the problem lies in whether you can avoid weaknesses and give full play to their respective advantages, and this is the most fundamental to do a good job of transformers.

Transformer quality is good for sound great impact, because the transformer's transmission energy and the core, closely related to the coil, the transmission rate of the sound play a decisive role. Like EI-type transformers, people usually think it's relatively thick intermediate frequency, high frequency is more slender, why? Because its transmission speed is relatively slow. And ring it? Comparison of low-frequency fierce, then slightly weaker in the high-frequency point, and why? Because of its faster transmission speed, but if through effective structural changes, you can ring and EI-type have done very perfect, so the key depends on how you do.
