An Experimental and Investigation on Asymmetric Modular Multilevel Inverter an Approach with Reduced Number of Semiconductor Devices

Abstract

The super-lift method has made numerous remarkable contributions to DC/DC transformation technology. Positive output super-lift LUO converters can simply raise the DC input voltage directly into a greater stage DC output voltage. The new approach of Asymmetric Super-Lift Multilevel Inverter (ASLMLI) DC/AC technology proposed with reduced number of components compared to the asymmetrical type of MLI. The comparison is made for open loop and closed loop control PI and Fuzzy controller used to reduce the harmonic content significantly with vary of modulation index. This architecture to design single phase 7-level ASLMLI is put forth for solar application with incorporating intelligent technique. This circuit uses a single MOSFET switch with less switching stress and single DC source. It generates low distortion output uses through the harmonic band of the FFT window by utilizing MATLAB/Simulink software and a hardware implementation. As a result, minimum THD valid through seven level cases compare with Traditional MLI.
