A New Cascade H-Bridge Inverter Based Multi-Level Statcom for High Power Applications

U. Rosaiah, M. Lokesh

Abstract: The industrial power sector and domestic power sector requires bulk power transfer from sources, in which reactive power and power quality (PQ) are the major issues. This paper presents cascaded H-bridge inverter based multi-level static compensator (STATCOM) using space vector pulse width modulation technique (SVPWM). The main objective is reactive power compensation with improved power quality. The topology consisting of two standard H-bridge inverters connected through a three-phase transformer. In high power applications, VAR compensation is achieved using multi-level inverters. The SVPWM is the best reliable advanced modulation technique, enables better DC bus utilization. In addition SVPWM produces fewer harmonic in the output voltage and current thus gives quality of power. The performance of the scheme is analysed through MATLAB/SIMULINK.
