| Abstract: |
| Regarding to problems of analog control circuit generally adopted in the electrolytic industry,such as the large offset of parameter,the insufficient control strategy and the low reliability,an improved circuit is proposed.It adopts the double inverse star circuit with paralleling reactor,PLL(Phase Locked Loop) technique to capture synchronization signal and relevant digital trigger equipment,which tracks the variation of the input signal frequency,overcomes the influence of the network voltage fluctuation and distortion,and accurately outputs the phase-shift trigger pulse for the thyristor rectifying circuit.Circuit parameters are designed with experimental study.Results prove that it achieves high control accuracy of rectifying current and realizes the monitoring of electrolysis process. |
