摘要
由于变频调速以其优异的高动态调速性能、高效率、节能和广泛的适用范围等,被国内外公认为最有发展前途的调速方法。所以本文对各种变频调速控制方式进行比较,如:SPWM、SVPWM、FOC、DTC和矩阵式交-交变频控制方式,并讨论变频调速存在的问题与发展方向。
Variable-Frequency Adjustable-Speed was accepted as most the development prospect the method because of its excellent and high dynamic properties, high-efficiency, economy and extensive use scope etc. so this text compare with a variety of variable-frequency adjustable-speeds, such as： The SPWM, SVPWM, FOC, DTC and the matrix type AC-AC variable- frequency control method, and discuss the problems about exsits in variable-frequency adjustable-speed and development direction.
