In addition to the difference between the SMPS transformers technology, wire shielding and copper shielding these two shielding effect is almost. Used in the specific power supply is not necessarily put on that good. As for why the use of wire shielding, the factors can be considered more, cost, efficiency and so on. Another point is to use the line shield can be more flexible to design, such as shielding the starting point, the end of the direction of the winding effect of this shielding effect will have a real impact.
With copper wire shielding costs will be low, it can be automated production, many SMPS transformers manufacturer have automatic machines; there are copper wire shielding when the production of products consistent with the results of good EMI test;
Some shielded copper wire is used to make up the winding, to adjust the internal winding capacitor, it is easy to adjust the number of laps in the charger transformer commonly used.
