A novel, efficient multilevel inverter topology has been proposed which generates the seven level output voltage using seven power switches only along with simple and modern pulse width modulation technique. This inverter has offered the advantages of, less component count, reduced switching loss, high efficiency and low cost. Due to the less number of switch components the complexity in generation...
This paper introduces a novel pulse width modulation (PWM) technique to eliminate common-mode voltage in odd-multilevel inverters using the three zero common-mode vectors principles. Similarly, as in conventional PWM for multilevel inverters, this PWM can be properly depicted in an active two-level voltage inverter. With the help of two standardized PWM patterns, the characteristics of the PWM process...
