This work represent induction motor modeling from its dynamic equations. The switching table base DTC(ST- DTC) is implemented to the dynamic machine model for 2 level and 3-level voltage source inverter. Out of 27 switching vectors of 3-level inverter, 12 active vectors are used for simulation of DTC with 12 sectors. For reduction of torque ripple a five level torque comparator is proposed. A comparison...
In an inverter, the number of legs can be increased to any number. So, any number of phase voltages can be generated with proper firing pulses. In this work, a five phase machine is modeled and simulated in MATLAB / Simulink. The space vector modulation (SVM) technique is applied to the proposed model for its torque control. The torque control characteristic obtained using SVM based DTC is compared...
The induction motor is generally fed from an inverter whose firing pulse can be easily modified according to the required output. The inverter fed motor drive removes the limitation of number of phases which led to the increasing application of the multiphase induction motor. In this work, a five phase induction motor with two-level inverter is mathematically modeled. The proposed model is simulated...
