摘要
电压源型逆变器,根据最大调制系数(MI)的大小逆变器工作在三种不同区域:线性调制、过调制Ⅰ和过调制Ⅱ区,不同的区域对应着不同的算法以实现线性控制逆变器输出电压。本文进行分析,针对过调制Ⅱ区提出参考电压矢量概念,简化了算法,并利用Intel公司80C1 96MC芯片实现,给出了实验输出波形。
Voltage source inverter may work in three diff er ent regions according to the value of Modulation Index(MI),There are linear modu lation,overmodulation mode (Ⅰ) and mode (Ⅱ). Different region requires dif ferent algorithm to produce lineared output voltage.This paper derived the prope r algorithm based on the analysis. Using Intel 80C196MC micro-processor to prod uce SVPWM wave,experimental results verified the validity of the algorithm.
