Multilevel Inverter & Soft Computing Technique Rup Narayan Ray

In this book, a detail discussion on multilevel inverter, soft computing techniques and optimization algorithm specially Genetic Algorithm (GA), Particle Swarm optimization (PSO), Harmony Search algorithm (HSA) and Cuckoo Search(CS) optimization algorithm are discussed and these soft computing techniques applied in multilevel inverter to compute switching angles at fundamental frequency switching scheme by solving non linear transcendental equations (known as selective harmonic elimination equations), thereby keeping certain predominating lower order harmonics within allowable limits, and simultaneously, control over magnitude of output voltage of a multilevel inverter is achieved. Optimization capability of THD minimization, computational time, FFT analysis has been studied for these optimization techniques in MATLAB environment.
