Five-level converter with selective harmonic elimination for STATCOM

In this paper, five-level Static Synchronous Compensator (STATCOM) is analyzed with reduced number of power switches. The simulation has been performed by using a digital signal processing unit (DSP) and Matlab/Simulink together. Selective harmonic elimination, single phase real (P) and reactive (Q) power methods are used to control power flow in the delta connected converter. The response of STATCOM is investigated under inductive loading conditions. All the control algorithm is programmed on DSP and grid connected AC/DC converter is simulated in Matlab/Simulink. The predicted results from Matlab and DSP TMS320F28335 have been presented.
