MW直流电弧的电流控制采用2台整流变压器控制，通过调节晶闸管桥触发角构成24脉波整流电路。

MW DC arc furnace uses the current 2-transformer rectifier bridge thyristor controlled by adjusting the angle trigger to compose 24 pulse wave rectifier circuit.

直流电弧炉用整流变压器漏抗值设计较一般电力变压器大，整流器换相时间延长。

Because leakage inductance value of rectiformer used in DC EAF is larger than common power transformer, the rectifier has longer commutation time.
