Comparative study of an efficient cascaded Inverter with different loads

Abstract

Inverter, a device used for conversion of dc power to ac power has evolved from simple two level converter circuit to multilevel converter systems using efficient configurations. It is of growing interest because of its applications in photovoltaic systems, high voltage direct current transmission system, flexible alternating current transmission devices, industrial drives, isolated power supplies, renewable energy integration etc. Each day much work is being attempted to make better configurations to reduce size, space and cost of the system. This paper discusses one such configuration which is more advantageous than existing configurations and can be easily implemented. It also presents the results of a comparative analysis with an existing configuration of wide acceptance. Control used is sinusoidal pulse width modulation for both topologies compared. MATLAB-Simulink is used to do the simulative analysis.
