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 submodules (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.
