Question:

Around the switch power transformer with a number of thin wire around or a few shares thick wire around, why?

Such as my primary with double shares 0.51 line, the secondary with four shares 0.51 line, if the secondary I used two 0.71 lines to replace the four shares of 0.51 line influential?

Answer:

If the skeleton of the transformer can be around, you can, with the purpose of multi-strand line: mainly to increase the coupling force of magnetic field lines, is conducive to EMC, as well as reduce the skin effect, of course, when the pin winding, too rough , Will generally be made in the form of flying line. The final choice or to cost, performance, easy to set up for the integrated consideration.
Transformer (Transformer) is the use of electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core (core). In electrical equipment and wireless circuits, commonly used as lifting voltage, matching impedance, safety isolation and so on. The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the use can be divided into: distribution transformers, power transformers, sealed transformers, modular transformers, dry-type transformers, oil-immersed transformers, single-phase transformers, electric transformers, rectifier transformers.
