A comparative study of cascade H-bridge multilevel voltage source inverter and parallel inductor multilevel current source inverter

Abstract

This paper presents the analysis study between multilevel inverters that are often classified into multilevel voltage source and multilevel current source inverters. For multilevel voltage source inverter (MVSI), the specific topology studied for this work is the Cascaded H-Bridge MVSI. Whereas, the multilevel current source inverter (MCSI) is based on Paralleled Inductor Configuration MCSI. For this study, the analysis between these converters are done with respect to the number of components, the advantages and disadvantages of each converters during performing inverter operation. In term of output voltage and current quality, the percentage of the Total Harmonic Distortion (THD) are measured and compared for both topologies. MATLAB/Simulink software has been used in this research to design and simulate in order to study the performances of both inverters.

Implementation of a modified carrier-based PWM technique for a cascaded MLI using DSP microcontroller

“…This is because the high-frequency switching reduces the size of the output filter needed to remove unwanted harmonics [20]. Overall, the choice of PWM technique depends on the specific requirements of the application, including the desired output waveform, the number of switching operations, and the complexity of the control circuit [21]. Each technique has its own advantages and disadvantages, and the optimal technique may vary depending on the specific application.…”

An efficient MPPT based photovoltaic control model considering environmental parameters

“…Incremental conductance method is used because of its easy and practical simulation and is also more compatible with environmental factors than other existing methods. The main technique of this method is based on the inclination of the array diagram in terms of voltage at the maximum power point [25], [26].…”
