摘　　要：在大功率整流电源的制作设计中,一个很重要的问题是如何解决输电线上交变电流对pn结的电磁影响。交变电流会在空间产生交变电磁场,交变电磁场的分布直接影响着整流电源中pn结的排列设计。各输电线上的交流电流都会在空间产生电磁场,其中输入输出交流电的两输电线对空间电磁场的分布起着举足轻重的作用。从麦克斯韦方程组出发,以有限长的平行直导线为模型研究了载有交流电的两输电线周围的电磁场分布,可以直接用于指导整流电源的设计。In the design of high-power electric source, it is important to eliminate the electromagnetic effect of AC currents flowing through living wires on pn junctions. AC currents create alternating electromagnetic field, which affects the design of the arrangement of pn junctions in the commutating electric circuits. Every AC current can generate electromagnetic field in the space around, while the input and the output AC currents flowing through alternating two living wire have significant impacts on the distribution of the alternating electromagnetic field. In this work, the distribution of alternating electromagnetic field AC currents flowing through two living wires was theoretically modeled for a configuration of twin-line of finite length. The results obtained are expected to be valid for practical applications in design of these families of electric power supply.
