| Abstract: |
| Aiming at the huge power consumption of traditional DC manganese electrolyzation，a synthetic energy-saving high-power interruptible 6-pulse rectifier system is proposed，which，based on the traditional 6-pulse rectifier system，blocks the triggering signal of thyristor for a certain period to achieve three variable parameters：frequency，duty cycle and current. The influences of these three parameters on the AC-side harmonic distortion are studied in detail and an inductive filtering transformer based on the harmonic flux suppression is applied at the valve side for restraining the harmonic close to its source and compensating the reactive power，which lowers the harmonic pollution and reactive power loss to a certain extent. Results of simulation and pilot test show that，the energy-saving effect of the proposed system is remarkable，verifying the high efficiency and energy saving advantage of the pulse-current manganese electrolyzation. |
