Abstract
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.
