COMPARISION OF THD ANALYSIS ON NEW TOPOLOGY MULTILEVEL INVERTER WITH SPWM & GA OPTIMIZATION TECHNIQUES

ELECTRICAL ENGINEERING

The emergence of multilevel inverters has been in increase since the last decade. This project presents a new technique for getting a multilevel output instead of cascaded H bridge inverter and also uses SPWM control technique. In this technique, the number of switches used for the dc to ac conversion is reduced. So this dc to ac conversion significantly reduces the initial cost. The main challenge associated with HR-PWM techniques is to obtain the analytical solution of the system for nonlinear transcendental equations that contain trigonometric terms which in turn provide multiple sets of solutions. An optimization technique assisted with a hybrid genetic algorithm was successfully applied to find the switching transitions (i.e. ., switching angles) of the HR PWM . More recently, a general genetic algorithm using Matlab GA optimization Toolbox was applied to solve the same problem of HR-PWM
