Optimized Modulation for AC–DC Harmonic Immunity in VSC HVDC Transmission ABSTRACT: Control methods based on selective harmonic elimination pulse-width modulation (SHE-PWM) techniques offer the lowest possible number of switching transitions. This feature also results in the lowest possible level of converter switching losses. For this reason, they are very attractive techniques for the voltage-source-converter-(VSC) based high-voltage dc (HVDC) power transmission systems. The paper discusses optimized modulation patterns which offer controlled harmonic immunity between the ac and dc side. The application focuses on the conventional two-level converter when its dc-link voltage contains a mix of low-frequency harmoniccomponents. Simulation and experimental results are presented to confirm the validity of the proposed switching patterns. Did you like this research project?
