-
摘要: 介绍了双变量控制基本原理,阐述了变压变频在双变量六脉波交-交变频器全范围调速系统中的应用;分析了传统变压变频的缺点,提出了采用对称余弦法对双变量六脉波交-交变频器的波形进行对称性改造的方法。仿真结果验证了双变量六脉波交-交变频器变压变频控制新方法的有效性。Abstract: The paper introduced basic principle of double-variable control,and described application of VVVF in full-range speed-regulation system with double-variable 6-pulse AC-AC converter.It also analyzed the limitation of traditional VVVF and put forward a method using symmetrical cosine method to reform the waveform of double-varible 6-pulse AC-AC converter.The simulation result showed that the effectiveness of the new control method of VVVF based on double-variable 6-pulse AC-AC converter.
