Power thyristor DC chopper technics are growing rapidly day by day in the applicatioh of electric traction,because it has an excellent control characteristic and an obvious effect to save electric power. The article discribes the research work of chopper contral equipment whiCh is used for the 100 tons electric Locomotive.EL_2-122 that belonged to An Snan Iron and steel Company,and also introduces its main technical features and economical effect.And the article emphatically point,out,although most analyses consider a multiple phase chopper has its obvious advantages,but the research work of EL_2-122 has proved that multiphase chopper circuit with not combine output has bigher reliability,so it is desirable.Finally,the practice of EL_2-122 shows,to reform the mine electrical locomotive is of great value not only in technics but also in economics.

大功率直流斩波技术已日益广泛地应用于直流电力牵引的领域中,因为它具有优越的调节性能和显著的节能效果。本文结合在鞍山钢铁公司100吨工矿电力机车EL_2-122上所进行的斩波调速研制工作,介绍了它的主要技术特点及经济效果。并着重指出,尽管一般认为多相多重斩波电路有明显的优点,但从实际运行的情况来看,多相不重的斩波电路却有较高的可靠性,因而是可取的。EL_2-122的运行实践证明,对矿山电力机车进行该项技术的改造,无论就其技术性能,还是经济效果来说都是很有意义的。

It is necessary to establish a precise and feasible modle to describe the impurity profiles in two p-layers of a thyristor for its numerical analysis. The author deal with the two-stage sealed tube diffusion process that forms the double diffused p-layers of a high power thyristor. The redistribution of Al in gallium diffusion process is particularly considered for diseribing its final profile, whereas a variable diffusion coefficient is employed to discribe Ga profile with higher surface concentration. Comparing the calculated results with the experimcnt data obtained by spreading probe measurement, we show that the model is practitally precise and feasible.

为了对晶闸管特性进行计算机模拟,有必要对其P区的杂质浓度分布建立准确而便于计算的模型。文中对形成P区二段式杂质分布的铝镓分步闭管扩散工艺进行了讨论。对较低浓度铝的最终分布着重考虑它在扩镓过程中的再分布,而对高浓度镓的最终分布则着重考虑扩散系数的变化。与实验样品的扩展电阻探针测试数据进行比较后表明,本工作所用模型与实验结果有较好的吻合,适宜于在实际工艺过程中使用。
