Modern day power systems, power electronic devices are playing vital role in every aspect of the power system network. Among various devices multi-level inverters are the most efficient devices due to their Simple circuit configuration, reliability and cost effective implementation. Application of multi-level inverters along with STATCOM using SPWM (Sinusoidal Pulse Width Modulation) technique improves the operation & utilization of power system. Because STATCOM injects reactive component into the power system during large disturbances. This paper deals with multilevel converter based STATCOM and the results are studied through MATLAB Simulink
