A New Switching Pattern for Multilevel Inverter Based on Selective Harmonic Elimination Using Genetic Algorithm
2014
Journal of international Conference on Electrical Machines and Systems
Preserved Fulltext
In this paper, a new switching pattern is presented for multilevel inverters. With changing off-angel of each switch, the on time interval of all switches will approximately be equal and then the lifetime of inverter will increase, al so using this method can reduce electrical stress on switches in higher levels of inverter. Switching angels as for desired modulation index are calculated using genetic algorithm whereas selective harmonics are controlled within the allowable range. The computed
