摘要
本文介绍12脉波变压器整流电路的两种结构,分析了12脉波变压器各次谐波含量及其对变频器整流的影响,分析了单机组12脉变压器整流电路导致两组变频器输入电流不平衡的原因,指出单机组与双机组12脉波变压器整流电路的优缺点。在12脉变频器应用系统中采用双机组12脉波整流电路结构,系统运行会更稳定。
In this paper,we introduce two structures of rectifier circuit of12pulse transformer.Theharmonic content of12pulse transformer and its influence on the converter rectifier are analyzed.The reasons for the imbalance of input current in two sets of converter are analyzed.The advantages and disadvantages of the rectifier circuit are pointed out.In the12pulse converter application system,The circuit structure of12pulse wave rectifier is adopted.the system will be more stable.
