Rectifiers with near sinusoidal input currents - MATLAB/Simulink model case studies

The concept of the rectifiers with near sinusoidal input currents (RNSIC) has caught increasing attention, different topologies been designed and analyzed. Even though the OrCAD/PSpice simulation package has proved its merits in the design and study of this type of converters, in order to analyze their integration in complex power electronic systems (such as: wind generator systems, photovoltaic power systems, electric drives), the most powerful simulation tool has proved to be MATLAB/Simulink. The present paper proposes a MATLAB/SimulinK simulation model for RNSIC converters, compares the simulation results with reported OrCAD/PSpice simulation and experimental results and analyzes a complex drive system which includes RNSIC-1 converter.
