amorphous transformer , the rational use of the performance of amorphous soft magnetic materials; is conducive to high-frequency power transformer products, standardization; is conducive to the efficiency of the transformer, the level of improvement; is conducive to inverter welding, plating, electrolysis And other equipment

The choice of coil magnetic material will determine the high power wireless charging system. Since the surface temperature rise of the low-power wireless charging system is not obvious, the physical properties such as the magnetic permeability and the resistivity are not prominent regardless of the type of magnetic material selected.

The design of the power supply filter is usually considered from both common mode choke coil and differential mode. The most important part of the common mode filter is the common mode choke. Compared with the differential mode choke, a significant advantage of the common mode choke is that its inductance is extremely high and the volume is small. Eccentric to consider an important issue is its leakage inductance, that is, differential mode inductance.

With the daily use of electrical equipment in the constant increase in the voltage requirements continue to improve, and sometimes when the voltage instability will cause damage to our electrical equipment, but also on our daily lives. In order to make the voltage in our daily use more stable, generally we will increase the installation of switching power supply transformer, the following is a basic introduction of some switching power supply transformers.

SMPS transformers

Magnetic beads composed of oxygen magnets, inductors from the core and coil composition, the magnetic beads to the AC signal into heat, the common mode choke coil to store the exchange, the slow release.

Magnetic beads on the high-frequency signals have a greater role in hindering the general specifications of 100 Europe / 100mMHZ, which at low frequencies when the resistance is much smaller than the inductor. Inductive equivalent resistance can be Z = 2X3.14xf to obtain.
