The Selective Harmonic Elimination Pulse-Width Modulation (SHE-PWM) is an effective method for harmonic elimination in multilevel inverter. This paper presents the solutions of Selective Harmonic Elimination (SHE) problem based on Genetic algorithm (GA) and Particle Swarm Optimization (PSO) techniques. Total Harmonic Distortion (THD) of output voltage is(More)
Subjects with sickle cell trait have been known to offer resistance to induced Plasmodium falciparum infection. The resistance to malarial infection in other haemoglobinopathic disorders is not clearly known. Investigations were undertaken to test for resistance to malaria in Hb E thalassaemia disease. Compared to controls, subjects with Hb E thalassaemia(More)
This paper presents 2D and 3D modeling of hysteresis motor using high temperature superconducting element Yttrium Barium Copper Oxide (YBCO) in the rotor. These hysteresis motors aim to improve the performance in comparison with that of conventional hysteresis motors. Various performance parameters of high temperature superconducting hysteresis motor are(More)
Minimum Total Harmonic Distortion (THD) is one of the most important requirements from multilevel inverter concerning good Power Quality. This paper presents the optimization of THD in 13 level Cascaded Multilevel Inverter with unequal dc source using Genetic Algorithm (GA). THD minimization is taken as an optimization problem derived from Selective(More)
