Item Simulation of SVPWM based FOC of CSI fed induction motor drive(2012) Ronanki, D.; Rajesh, K.; Parthiban, P.The application of current source inverters (CSI)in induction motor (IM) drives offers a number of advantages, including voltage boosting capability, natural shoot-through short-circuit protection and generation of sinusoidal voltages. In this paper, an attempt to model the CSI fed IM drive is presented. The mathematical model takes into account of the inverter, and induction motor dynamics and is established in the stationary reference frame. For controlling the drive speed, a direct field-oriented control (FOC) is proposed. To counter the effects of torque pulsations at very low speeds and the rotor resistance variation, a slip angle compensation loop is included in the control law formulation. Analytical expressions for CSI fed IM with Direct FOC are derived and validated using MATLAB/SIMULINK. � 2012 IEEE.Item Simulation of SVPWM based FOC of CSI fed induction motor drive(2012) Ronanki, D.; Rajesh, K.; Parthiban, P.The application of current source inverters (CSI)in induction motor (IM) drives offers a number of advantages, including voltage boosting capability, natural shoot-through short-circuit protection and generation of sinusoidal voltages.
