| Abstract: | 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. |
