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...
Reliability and power quality are two aspects of motor drives which have been gaining the attention of the industry. In fact, as the processes increased in number and complexity, the criticality of each component also increased. This paper proposes the usage of a PWM rectifier to accomplish a fault-tolerant motor drive with optimal performance and power quality. The system uses a hardware reconfiguration,...
Induction motors are most popularly used in modern day industrial drives. Under operating stresses and ageing, both stator and rotor of an induction motor undergoes degradation. It is necessary to properly assess the condition of motors on operation for reliable performance. Popularly employed technique for motor condition monitoring is the motor current signature analysis (MCSA) that deals with frequency...
This paper presents a minimization technique of the position detection error resulting from the zero current clamping (ZCC) effect for pulsating high-frequency (HF) signal injection-based sensorless drives. An analytical model is derived to obtain an accurate map of the ZCC effect of the PWM inverter. This model is universally agreed upon and subsequently incorporated into the development of a specialized...
