This paper presents a discrete space vector modulation (DSVM) algorithm based vector controlled induction motor drive for reduced torque and current ripples in steady state. Though, the conventional vector control algorithm gives good transient and steady state response, the complexity involved is more due to the reference frame transformations. Later, the direct torque control (DTC) was developed...
Simple and novel vector based hysteresis current control schemes are presented for vector controlled induction motor drives. The proposed algorithm combines the principles of direct torque control (DTC) and field oriented control (FOC). The proposed algorithm generates the reference currents as per the principle of vector control algorithm. The, the vector based hysteresis comparators integrated with...
In this paper, design of auto transformer based 18 Step AC-DC converter fed vector controlled Switched Reluctance motor drive is presented and its Matlab /Simulink model is given. The design procedure for proposed autotransformers shows the flexibility in the design for making it a cost effective replacement suitable for retrofit applications, where presently a six pulse diode bridge rectifier is...
