Amorphous alloy has been in 2004 after a fire, when the silicon steel sheet because the supply is far less than demand led to the price rose, making the price of amorphous alloy transformer and the price of ordinary silicon steel transformer is no longer as large as ever, amorphous Alloy transformer has been looked up. However, with the 2008 Baosteel silicon steel batch off the assembly line, making silicon steel prices all the way down,…Continue

Switching power supply inductor from common mode choke manufacturers is an important component, which is the use of electromagnetic induction principle of work. It is the role of resistance to AC-DC, high-frequency pass-resistant low-frequency (filter), which means that high-frequency signal through the coil will encounter a lot of resistance, difficult to pass, and low-frequency signal through it The resistance is…Continue

Electronic transformer definition:
Electronic transformer, with the alternating current voltage into the DC and then through the semiconductor switching devices and electronic components and high-frequency transformer windings constitute a high-frequency AC voltage output of electronic devices, but also in the electronic theory of a described Intersection and Intersection Inverter.
In short, it is mainly by the high-frequency transformer core (core) and two or more…
