Özet

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.
