摘要
分析了特定消谐PWM技术的基本原理,设计了一种基于可编程逻辑器件CPLD和特定消谐PWM技术的单极性单相逆变器触发脉冲发生器,并将其用于所设计的单相逆变器。仿真和样机实验结果表明,逆变器输出谐波含量少、开关损耗小、效率高,同时外围电路简单、可靠性高、实时性好。
On the basis of analyzing the basic principle of selective harmonic elimination（SHE） technique,a kind of singlephase and unipolar pulse generator using CPLD and selective harmonic elimination technique was designed and an inverter was developed.The simulative and experimental results show the inverter has the advantages of low harmonic output, small switching loss, high efficiency, simple peripheral circuit and good real-time
