摘要
本文介绍了一种新型循环变频器，该变频器以时空多相变频、空分输出为理论，从而实现循环变频、移相调压的目的。相对于目前较为广泛使用的静止式循环变频器，能较简单灵活地控制电机实现四象限运行，在电气传动、自动控制等领域有着广阔的发展前景。
This paper introduces a new type of cireulatory frequency converter. The theoretical basis of this kind of converter is multi-angre variabe frequency for time and space, space -carving output, then it is re-alized to convert frequency circulatively and adjust output by moving angles. Comparing with the static fe-quency converters which have been widely used recently, this NCFC can simply and flexibly control motor to realize infinite running. It would have broad prospect in fields of electric drive and automatic control.
