At the same time, before the diode bridge rectifier it USES filter circuit with a simple harmonic suppression which can not fulfil the complete harmonic suppression.

Considering existing limitation, a full-fresh voltage multiplying bridge rectifier circuit is presented, and the theoretical derivation and numerical simulation are carried out.

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.
