Saturable reactor type welding transformer is popular used in welding. The welding transformer reduces the voltage from the source voltage to a lower voltage (usually between 15 and 45 volts) that is suitable for welding. In this welding transformer an isolated low voltage, low amperage dc circuit is employed to change the effective magnetic characteristics of the magnetic core. Coilcore focus on ...

As we know, the inductance value will influence inductors application, today let’s talk about how to select an inductors based on inductance value. During the inductance is almost not stable during the entire working period of the components,  understand the effective value scope is particularly important. Thus, you should know your power circuit's inductance scope clearly. For inductors in p...
