Abstract: In this paper a Multilevel current source converters is utilized for the high power applications with high current low and voltage requirements. Therefore we can totally analysis of a current source modular multilevel converter (CSMMC) with its application such as STATCOM. There are different properties of CSMMC which are correlated with the voltage source modular multilevel converter (VSMMC). There are two method for inductor current balancing they are sub module inductance selection method and a sorting based algorithm which are proposed for CSMMC. Moreover for the switching technique we are implementing the carrier phase shifted sinusoidal pulse width modulation. Here the performance of a converter can be analyzed under non-interleaved and interleaved carrier signals during the upper and lower arms. Here we are using the fuzzy controller compared to other controllers i.e. The fuzzy controller is the most suitable for the human decision-making mechanism, providing the operation of an electronic system with decisions of experts. Simulation Results will show that CSMMCs which is corresponding VSMMCs have analogous features. Hence, for the reference of CSMMCs and vice versa we are using the developed VSMMCs. Furthermore, the control satergy for CSMMC which is depend upon the STATCOM are presented and also proven by using simulations. The proposed STATCOM will display that the transient and steady state performance of the system are satisfactory.
