3. Working Principle

The device changes the saturation of iron core based on the DC optimized magnetism and additional DC magnetic core to realize continuous change of inductance. The schematic diagram is as follows:

Two coils, of which number of turns is N/2, are respectively and symmetrically winded on the iron core column of controlled reactor. The tap with tapping ratio of 1-2% is placed on the coil and used as excitation source. They are connected with controlled silicon T1 and T2. The main windings of different iron cores are crossed and then connected to power supply system, then connected by two thyristors in turns in order to control the saturation of iron core.
