摘　　要：根据大功率(P>100 kW)电动机一般以低转速运行的特点,采用按规律截除波形的全新方法,将交流电直接降低频率驱动电动机以获得较低的转速,可以去除通常减速机械装置,有效地提高效率。Considering that the high-power （P 〉 100kW） electromotor commonly runs at a low rotating speed, the paper adopts the new method of cutting waveforms according to laws in order to drive the motors by directly lowering the frequency through AC and obtain a lower rotating speed. In this way, the reduction gear can be removed and the efficiency is effectively increased.

关 键 词：截波 单片机 波形补偿
