SCR Rectifier 38kA40V for electric arc furnace heating
Our SCR rectifier has been widely used as a external DC power supply for industry factories in many countries and got the customer's high praise and affirmation.
2. Working principle
The power supply main circuit topology structure is 12 pulse double star rectification, convert AC 3 phase 11KV to 41V through transformer, then 0~40V DC voltage, shown as the picture above. It adopts water cooling method, has over heat, output over voltage/current, water under pressure, limit voltage/current etc. protection functions. If failure, there will be alarm. Every bridge arm is parallel connected by three thyristors (one for spare), if one thyristor is broken, the other two could still work normally.
