摘　　要：介绍了变频调速中的主要环节IGBT逆变器的工作原理,异步电机的变压变频调速简称为变频调速系统,阐述了变频调速的原理,并分析了变频调速具有调速范围宽、启动电流比直接启动电流小、无论是高速还是低速时效率都较高等特点;在Matlab中采取相应技术措施后能实现高动态性能,可与直流调速系统相媲美;通过软件对逆变器变频原理进行仿真,进一步推广了其应用范围。The working principle of the key link of IGBT inverter with variable voltage and variable frequency（ VVVF） is introduced. Variable voltage and variable frequency of asynchronous motor is called VVVF system for short,VVVF principle is briefly narrated,wide speed control range of VVVF is analyzed,and the efficiency is high whether high speed or low speed is when starting current is smaller than the directly starting current. High dynamic performance is achieved by taking the corresponding technical measures in Matlab,which is comparable with DC variable voltage system. Its application range is further expanded by using software to simulate the variable frequency principle.
