摘要
对多相不可控整流电路输出电压的谐波分量进行了分析；提出了用两组三相桥串联组成十二相整流电路的设计思路；介绍了研制成功的三相桥串联晶闸管调速系统的构成原理及达到的性能指标。该系统功率达到４０００ｋＷ，电流达２５００Ａ；调节时间为１７ｓ，静态精度为０．２％。
This paper analyses the high frequency wave component of multi phase uncontrollable rectification circuit output voltage, and provides an idea to from 12 phase rectification circuit with two 3 phase bridges in series; It also describes the principle of successful 3 phase bridges in series SCR speed regulation system and its performance criteria. The power of the system reaches 400kW,with 2500A current, 17s adjusting time and 0.2% static precision.
