This paper presents state space model of singlephase STATCOM based on continues switching function. Continues switching functions for bipolar voltage source inverter (VSI) have been used to derive the transfer function for complete controller. Two proportional integral (PI) controllers which are a DC PI for DC link voltage control and an AC PI for alternating current control are implemented in cascade topology in reactive power compensation. Proposed control method has been analyzed in simulation by using MATLAB. Root locus technique is used to design AC PI controller parameters

In this paper, a three-phase, Y-connected, five-level static synchronous compensator with reduced number of switches is proposed for single phase and unbalanced three-phase loads. The level shifted carrier based sinusoidal pulse width modulation method is used for switching. The active and reactive powers demanded by the load are estimated for each phase independently to compensate the reactive power supplied from the power system. The simulation results obtained from Matlab are compared with the results of experimental work and dedicated model of the proposed system. The system is implemented in the laboratory by using DSP TMS320F28335.
