Analysis of New Reduced Device Count MLI Using Different PWM Techniques

Abstract: . In this paper a “Analysis of New Reduced Device Count MLI Using Different PWM Techniques”. Since Penetration of multilevel inverters (MLI) in to high power and medium voltage application has been increasing because of its advantages. . The invention of MLI led to the increase in power rating of the devices, as the number of output voltage levels also increased. Even though many MLI topologies have been proposed over the years the elementary concept of a multilevel inverter remains the same, i.e., to achieve higher power output using several series connected power semiconductor switches and multiple low valued DC sources. And DC to AC convertors are playing an important role in various medium and high power applications.
