The asynchronous motor is widely used for its simple construction, ruggedness, high working reliability, relatively low cost, and high environmental adaptability. it is suit for the direction of high voltage, high speed and large capacity. vector control is its ideal speed modulation method. the harmonics of three - level inverter are less than the traditional two - level inverter ’ s, and it is convenient to realize high sinusoidal voltage output. the maximum voltage strength which each electric component bears is small, and it is easy for three - level inverter to realize large capacity. the research on the asynchronous motor vector control based on the three - level inverter is one novel work
異步電機結構簡單、堅固耐用、運行可靠、成本低、環境適應性強，容易向高壓高速和大容量方向發展，獲得了廣泛應用，矢量控制為其理想的調速方法;三電平逆變器輸出端諧波少，有利於實現輸出電壓的正弦化，且單個開關管承受的最大電壓小，適合向高壓大容量方向發展。對基於三電平逆變器的異步電機調速系統開展矢量控制研究，是一件有意義的工作。 -
