摘要
介绍一种用中功率IGBT低压变频器调节大功率风机和泵用中压电机转速的方法———转子变频调速。主电路简单 ,无大变压器及电抗器 ,运行功率因数高 ,谐波小 ,起动和旁路容易。
A new high power medium voltage variable speed drive (rotor side variable frequency drive)for fan or pump by using a medium power low voltage IGBT inverter is introduced in this paper. The features of the new method are simple main circuit,without big transformer and inductor,high power factor and low harmonics,easy to start and by pass operation.
