Reduced Power Electronic Componets Using a New Cascade Structure in PV cell based three phase Multilevel Converter fed Induction Motor Drive Application

Abstract

Multilevel inverters have an attracted a great deal of attenuation in medium voltage and high power application Due to their lower switching losses, EMI, high efficiency.Power electronic inverter become popular for various industrial drives applications. The multi-level inverter system is very promising in ac drives. Large electrical drives and utility application require advanced power electronics converter to meet the high power demands. As a result, multilevel power converter structure has been introduced as an alternative in high power and medium voltage situations.In this paper, a new configuration of a three-phase 25 -level multilevel voltage source inverter fed induction motor drive applications is introduced.The benefits of multilevel inverters are especially clear for medium-voltage drives in industrial applications and are being considered for future naval ship propulsion systems. Considering the cascaded inverter to be one unit, it can be seen that a higher number of voltage levels are available for a given number of semiconductor devices. Finally an asymmetrical configuration is proposed with this we are getting 25 levels with ten switches and same configuration is implemented to Induction Machine Drive to check the drive performance. The results are obtained through Matlab/Simulink software package.
