Comparative Study of THD in Multilevel Converter Using Model Predictive Controller

摘要

The topology of comparing the performance of the 5 level multi-level inverter with the 3 level multi-level inverter is proposed in this article [1]. A multilevel converter is a power electronic unit designed to examine a necessary AC voltage from many DC. which generates the output voltage with reduced complexity when regulating current and balancing the capacitor voltages. A megawatt power level and medium voltage are required for certain industrial drives. It is problematic for a medium voltage to directly link just one power semiconductor switch. As an option in low voltage and high power conditions, A multilevel power converter system has been incorporated. In this article, the five-level inverter is used to reduce the THD when evaluating the 3-level inverter. For multilevel converters, The strategy of the SVPWM control technique is used to bring down the THD in the waveform of the output. The simulation takes place in the framework of MAT LAB/Simulink.
