Abstract

This paper deals with analysis, simulation and control of a two level 48-pulse voltage source converter for High Voltage DC (HVDC) system. A set of two-level 6-pulse voltage source converters (VSCs) is used to form a 48-pulse converter operated at Fundamental Component of Switching Frequency (FCSF). The performance of the VSC system is improved in terms of reduced harmonic level at FCSF and THD (Total Harmonic Distortion). The performance of the VSC is studied to improve power factor and reduce harmonic distortion. Simulation results are presented for the proposed two level multi pulse converter.
