摘要
本文所讨论的马鞍波电流变频器,其可控硅及相应的控制元件比常规系统减少了1/2;矢量控制理论的应用,使控制性能得到改善;电势前馈补偿的加入,使电流跟随能力提高,并使系统成为无静差系统。
In the saddle-backed current-source cycleconvertor, power elements-SCR and the relative control elements are all the half against the conventional ones. The application of vector control theory has improved the property. An EMFfeedforward compensation has been added. This aims to improve the following ability of the realistic current and makes the system a non-state-error one.
