The dc sources that feed the multilevel inverter are varying in time, and the switching angles should adapt to the dc source variations. Any variations in the input will result in harmonics at the output. To mitigate the harmonics in the inverter output, GA is used. A genetic algorithm optimization technique is applied to determine the switching angles for a cascaded multilevel inverter. Then, ...

This paper presents detailed modeling and simulation of a compensator for Load balancing and harmonics Compensation based on a five-level cascaded H-bridge multilevel voltage source inverter.
