摘要
常规的空间矢量控制方法需要进行复杂的正弦函数、反正切函数运算 ,由低成本的单片机控制系统实现较为困难。本文提出了一种空间矢量的简化算法。该方法根据参考电压矢量在αβ坐标系上的分量 ,直接计算电压空间矢量在各个扇区内的作用时间 ,简化了运算过程。并以Intel80C196MC单片机为控制核心设计制作了一套三相PWM整流器的实验装置。
A simplified algorithm is proposed in this paper for space vector PWM rectifier. This algorithm avoids the look up tables of sine and/or arc tangent and complex calculations needed in the conventional methods by directly calculating the duty cycles of space voltage vectors tracking the reference voltage vector in each sector in the space vector plane. Experimental results with an Intel 16 bit microprocessor of 80C196MC validate the proposed algorithm.
