Modular-Multilevel Inverter based on Various Switching Modules for Harmonic Elimination in HVDC

Abstract

For transmitting the power and reducing harmonic distortion at long distance HVDC system in industrial application the Modular Multilevel Converter (MMC) is utilized. While contrasted and AC system, HVDC system utilized this technique as a result of its cost effective function, effectiveness of high transmission rate. MMC is for the most part utilized for reducing the filter size. In industrial application, it is extensively used for voltage balance, control of circuiting current at each arm and reduces the voltage ripple. In this paper MMC based various switching modules are used to mitigate the Total Harmonics Distortion (THD) that presents in the HVDC line. MMC has used in HVDC and LVDC applications. MMC is analyses and concludes the advantages and enhancement of converter modulation for reduce the voltage ripple.
