A Novel Multilevel Converter Used For Three Phase STATCOM under Unbalanced Load

In this paper, multi-level cascaded Static Synchronous Compensator (STATCOM) is proposed using a novel converter having reduced number of switches. STATCOM is analyzed by using DSP and Matlab, interactively. The level shifted carrier based SPWM method, instantaneous single phase active (P) and reactive (Q) power algorithms are applied to control this converters. The performance of STATCOM is investigated for unbalanced reactive load conditions. The simulation results of Matlab alone and Matlab interactively operated with DSP TMS320F28335 are presented.
