摘　　要：电压空间矢量SVPWM脉宽调制是交流伺服系统不可缺少的控制模块。基于数字信号微处理器的众多伺服系统设计者中,对其脉宽调制数字化的算法只是按例进行照搬,并未深刻理解公式及含义,造成设计调试困难和不能很好的解决电机实际运行中出现的问题。本文将从SVPWM脉宽调制原理给予介绍,推导出实用的计算公式,给出加载波形。Voltage space vector pulse width modulation SVPWM is an indispensable control module of AC servo system.Among the many servo system designers based on digital signal microprocessor control,the digital pulse width modulation algorithm is only compiled according to the relevant data,without a deep understanding of its meaning,which causes difficulties in design and debugging and fails to solve the problems in the actual operation of the motor.This paper introduced the principle of SVPWM pulse width modulation,deduced the practical calculation formula algorithm,and gave the loading waveform.
