Direct torque control is an utmost control technique to attain high performance of AC drives. This paper presents controlling of 3-phase Induction Motor (IM) fed from a 3-level Modular Multilevel Converter (MMC) topology which results in minimization of torque and flux ripples when compared to a 3-level Neutral Point Clamping (NPC) inverter based on Direct Torque Control(DTC). As well this in turn can reduce the Total Harmonic Distortion (THD) of the output current and voltage. In recent, modular multilevel converters are becomes popular due to their excellent scalability, redundancy and lesser harmonics for high power applications. The objective of this paper is to improve the steady state and dynamic performances of 3-phase induction motor fed from MMC with DTC using MATLAB/Simulation.
