摘要

本文比较了五电平级联h桥多电平逆变器开关角获取的两种方法——选择性谐波消除法和粒子群优化算法的总谐波畸变。给出了这两种方法的程序，并分别得到了理论的总谐波失真值。在实验室样机中验证了两种技术获得的开关角的理论结果，并与电能质量分析仪进行了总谐波失真比较。

Optimal Switching Angles Calculation for a Multilevel Inverter through the SHE Method and the PSO Algorithm, a comparison

This paper shows a comparison in terms of the Total Harmonic Distortion between two techniques to obtain the switching angles of a five-level Cascaded H-bridge Multilevel Inverter, the Selective Harmonic Elimination method, and the Particle Swarm Optimization algorithm. The procedure for both techniques is shown and a theoretical Total Harmonic Distortion value is obtained for each one. Theoretical results of the obtained switching angles for both techniques were verified in a laboratory prototype, where a Total Harmonic Distortion comparison was made with a Power Quality Analyzer.
