摘　　要：针对六脉波交交变频调速技术在高频段存在各频级间转速差较大的问题,提出了一种基于六脉波交交变频的闭环调压调速方法。该方法在2个高频段之间设置多个电压等级,通过改变交交变频输出电压的大小,进行交交变频闭环有级调压调速。仿真和实验结果表明,该方法能够有效利用存储器空间,扩大交交变频调速范围,调速效果较好。In view of problem of bigger speed difference between frequency levels in high frequencies in speed regulation technology of six-pulse-wave AC/AC frequency converter, the paper proposed a closed- loop voltage and speed regulation method based on six-pulse-wave AC/AC frequency converter. The method sets many voltage levels between two high frequencies, and changes output voltage of AC/AC frequency converter to realize closed-loop step voltage and speed regulation of the AC,/AC frequency converter. The simulation and experimental effectively, expands speed regulation range of regulation effect. results show the AC/AC that the method can frequency converter, use memory space and has good speed
