Drive systems are prevalent in industrial application of induction motors; while shunt FACTS devices are important to compensate disturbances and increase motor speeding up. In this paper an assessment study between Space Vector PWM (SVM) induction motor drive system and shunt FACTS (such as SVC) installed on terminals of motor is done. It is shown that shunt FACTS is more suitable than Induction...
This paper introduces a new scheme to track the rotor slotting saliency in induction motors by using the measurement of current derivatives in response to test vectors imposed during null switching vectors of a standard PWM scheme by using 3 H-bridges connected in series with a 2-Level inverter. The scheme aims to reduce the current distortion usually introduced by applying the sensorless control...
In this paper, an accurate position estimation method is reported for salient-pole brushless dc motor drives or permanent magnetic synchronous motor drives. The method is proposed for obtaining the position angles, the accuracy of which affect the operation of the switching devices of the inverter that drives the motor. First, the method for estimating the position angle is proposed. Secondly, the...
This paper presents a voltage controlled scheme for brushless DC (BLDC) motor drives. The scheme combines both the low speed PWM control and the high speed phase advance commutation to obtain an extended speed range drive feature. In addition, the proposed scheme does not have a current control loop. Hence, no current sensor is needed in the drive. To satisfy the required over load protection demand,...
