变频器的发展和应用

The Development and Application of the Converter

介绍了变频技术的发展(功率开关器件向大功率、耐高压的方向发展,控制技术向矢量控制和直接转矩控制发展),论述了交流变频器在节能调速、特大容量和极高转速的交流调速中的应用,并指出了应用时应注意的事项。

This paper introduces the development of the convener （the power switching device develops toward the high-power and high-voltage direction, and the control technique develops toward the vector-control and direct-torquecontrol direction）, expounds the application of the AC convener in the AC speed-regulation with energy-conservationbased speed-regulation, super capacity and extreme high rotational speed, and point out some matters needing attention in the application.
