摘要
针对目前电化工业电解槽极化电源主电路普遍采用晶闸管相控整流方案存在的不足,提出了采用不可控整流-斩波变流技术的新型主电路方案。设计了系统方案,介绍了系统主电路结构及工作原理,并分析了器件参数及器件选型。阐述控制电路的设计及控制方法分析,最后建立仿真模型并进行仿真分析。仿真结果表明:该方案具有输出电压稳定、谐波含量少、动态性能好等特点,能有效提高电源系统功率因数,且效率在97.5%以上,具有较好的应用价值。
In view of the deficiendcy of the thyristor rectification circuit mainly adopted by polarization electrical source in electric tank of electrochemical industry, the paper puts forward a new electrocircuit plan of uncontrollable rectification-variable chopped wave technology. It designs the systematic plan, and introduces instruction and operation principle of the main circuit, and analyses the device parameter and its lectotype. The paper states the controllable circiut design and the analysis of the controll methods. Simulation model is built and analyzed at last. The results make clear that this plan has such characteristics as stable output voltage, little harmonic wave, good dynamic function and so on, which can raise the power factor of electric sourcewith the efficiency above 97.5%. The design has good application value.
