Investigating the Performances of Direct Torque and Flux Control for Dual Stator Induction Motor with Direct and Indirect Matrix Converter
This work investigates the performances of Direct Torque Control (DTC) of Dual Stator Induction Motor (DSIM) powered by two types of Matrix Converter (MC), namely the direct and indirect MC. To this end, the design of DTC with conventional Direct Matrix Converter (DMC) is firstly presented. Then, in order to illustrate the main feature of Indirect Matrix Converter (IMC) in terms of the output voltages and input currents waveforms, the full steps of IMC are well explained. To discuss the performance of each scheme, both techniques are simulated in the Matlab / Simulink environment for a 4.5 kW DSIM at different operating conditions. The obtained results show that the IMC provides high performance in torque and flux at different conditions and while minimization the Total Harmonic Distortion (THD) in the input current compared by the conventional DMC.
