Comparative Performance Analysis of Induction Motor Using Semiconductor Devices in Terms of Firing Angle
نویسندگان
چکیده
Due to harmonics, sudden voltage dips and large fluctuating torque causes a great problem in the starting of large induction motor. Some times due to tripping of relay, equipment failure, surge, no load or overload motor voltage fluctuates resulting in the failure of motor starting. This paper discusses the solution of these problems by using soft starter technique. Soft starting of induction motor is obtained by using power switching devices. In this paper THD is calculated by various firing angles, and influence of load variations in terms of firing angle has been investigated for Thyristor and IGBT (Insulated Gate Bipolar Transistor). Keywords— Variable speed induction motor, Soft Starter, Thyristor, IGBT, Firing Angle, THD.

Background: Electromyographic (EMG) signal decomposition is the process by which an EMG signal is decomposed into its constituent motor unit potential trains (MUPTs). A major step in EMG decomposition is feature extraction in which each detected motor unit potential (MUP) is represented by a feature vector. As with any other pattern recognition system, feature extraction has a significant impac...
