Optimal Switching Angles Calculation for a Multilevel Inverter Through the ABC Algorithm

This paper explores the use of the artificial bee colony algorithm to obtain the switching angles of a five-level Cascaded H-bridge Multilevel Inverter. The objective of the algorithm is to reduce the Total Harmonic Distortion in the inverter output voltage. These switching angles are compared in a laboratory prototype with the fsolve method, which is included in the Matlab software. The results show a better Total Harmonic Distortion of the output voltage compared with the fsolve method.
