摘要
文章提出了一种适用于任意多相逆变器的 PWM算法 ,该算法简洁易行 ,并能够实现在线选取不同的调制方式 ,以满足不同控制的要求。还分析了采用多相空间电压矢量控制时 ,一个周期内电压矢量的合成过程 ,由于多相逆变器可供使用的空间电压矢量数目多 ,因而能够准确地输出给定电压矢量。用一套 15相变频调速系统所作的实验 ,验证了算法的正确性。
A new algorithm of PWM for multiphase inverter is proposed. It is concise and can be easily implemented and allows selecting appropriate PWM rule on line for different control task. The composition processing of the space vector is also been analyzed,the reference voltage vector can be achieved correctly because there are more space voltage vector can be utilized. The correctness of the algorithm are verified by a laboratory test on a 15 phase drive system.
