THD Minimization and Fault Analysis of Modular Multilevel Converters
Journal Title: International Journal of Trend in Scientific Research and Development - Year 2021, Vol 5, Issue 5
Abstract
Modular Multilevel Converters M2Cs have become an interesting topology for dc ac conversions and vice versa showing advantages of high modularity, extensible, fault tolerant ability, high quality output and decreased harmonics. Number of converter sub modules SMs operates in a sequence, generating multilevel output voltages and currents. This manuscript focuses on the comparative analysis of M2Cs based upon the total harmonic distortion THD under the application of LCL filter. The objective of filter application is to ensure that voltage harmonic distortion at the point of common coupling is less than 5 . Also, a fault monitoring scheme to detect and localize M2C SM switch failures is discussed. The presented scheme detects and localizes the fault in relatively lesser time. Simulation results are presented in order to verify results based upon the prototypes with 5, 7 and 9 level M2C. Er. Amit Kumar Paswan | Er.
