Abstract: A Direct Torque Control (DTC) scheme is proposed to provide the control of the proposed inverter. There are many techniques available for DTC scheme. In this thesis DTC scheme is achieved by implementing Space Vector Pulse Width Modulation (SVPWM) technique. A Sample Reference Frame (SRF) algorithm is used to implement SVPWM and it is compared with Sector Identification (SI) algorithm, Level Shift Multi Carrier (LSMC) algorithm and Third Harmonic Reference (THR) algorithm. The SRF algorithm is implemented in this proposed work with digital controllers and it has less memory space when compared to other algorithms.
Keywords: Multi level Inverter; Frame Algorithm, Torque Control.
