Analysis And Comparison Of Flying Capacitor And Modular Multilevel Converters Using SPWM

2016 unpublished
Multilevel inverters are considered as one of the best solutions for high power and medium voltage applications due to their reduced THD, dv/dt stresses, lower switching frequency, reduced EMI and EMC issues etc. This paper presents the analysis and comparison of three level Flying Capacitor (FC) or Capacitor Clamped multilevel inverter and Modular Multilevel Converter (MMCs) topologies. For the topologies mentioned above the simulations were carried out for resistive load. The PWM used here is

By comparing the THDs the advantages of Modular Multilevel Converter over the conventional Multilevel inverter is confirmed. The simulations are performed using MATLAB/SIMULINK software and the results are presented.
