abstract: In industries, for adjustable speed operation various types of drives are used. These drives are categorized in to AC drives and DC drives. DC drives were popular due to its overall performance, efficiency, static and dynamic characters. However it is suffers from major drawback of higher initial cost and maintenance cost. The advancements in semiconductor devices have made significant contribution in AC drives and also made AC drives equally competitive to DC drives. The AC drives are fed from either Voltage Source Inverter (VSI) or Current Source Inverter (CSI) VSI fed drives has proven to be more efficient, with higher reliability and faster dynamic response, compared CSI fed drives and capable of running motors without de rating. Hence fed drives VSI saves money with higher efficiencies, minimizing install time, eliminating interconnect power cabling costs, and reducing building floor space. The VSI drive PWM inverter along with rectifier and capacitor filter circuit from the basic structure of any AC drives.

abstract: This paper presents a predictive current control method and its application to a voltage source inverter. The method uses a discrete time model of the system to predict the future value of the load current for all possible voltage vectors generated by the inverter. The voltage vector which minimizes a quality function is selected. The quality function used in this work evaluates the current error at the next sampling time. The performance of the proposed predictive control method is compared with hysteresis and pulsewidth modulation control. The results show that the predictive method controls very effectively the load current and performs very well compared with the classical solutions

abstract: The new direct self control (DSC) is a simple method of signal processing that gives converter fed three phase machines an excellent dynamic performance. To control the torque of, say, an induction motor, it is sufficient to process the measured signals of the stator currents and the total flux linkages only. In the basic version of DSC, the power semiconductors of a three phase voltage source inverter are directly switched on and off via three Schmitt triggers, comparing the time integrals of line to line voltages to a reference value of desired flux, if the torque has not yet reached an upper limit value of a two limit torque control. Optimal performance of drive systems is accomplished in steady state as well as under transient conditions by combination of several two limit controls.

abstract: A six phase six step voltage fed induction motor is presented. The inverter is a transistorized six step voltage source inverter, while the motor is a modified standard three phase squirrel cage motor. The stator is rewound with two three phase winding sets displaced from each other by 30 electrical degrees. A model for the system is developed to simulate the drive and predict its performance. The simulation results for steady state conditions and experimental measurements show very good correlation. It is shown that this winding configuration results in the elimination of all air gap flux time harmonics of the order (6v 1, v 1,3,5, Consequently, all rotor copper losses produced by these harmonics as well as all torque harmonics of the order (6v, v 1,3,5, are eliminated. A comparison between the measured instantaneous torque of both three phase and six phase six step voltage fed induction machines shows the advantage of the six phase system over the three phase system in eliminating the sixth harmonic dominant torque ripple.

abstract: In this paper modelling and simulation of control strategy for Z source inverter is presented. The performance of single phase induction motor is studied with the control of single phase Z source inverter using Simple boost controller. This controller senses the motor speed feedback signal and consequently provides the pulse width modulated (PWM) signal that sets the gate voltage of the inverter, which in turn provides the required voltage for the desired speed. The proposed drive system is simulated using MATLAB/Simulink. The simulation results were compared with the experimental results.

abstract: This paper develops an real time inverter fault diagnosis method for induction motor drives based on the subtractive clustering analysis of the stator current vector and a quick mean current vector calculation method. A subtractive clustering algorithm for analyzing the mean current vectors under both normal and faulty inverter condition is conducted off line to verify the effectiveness of the mean current vectors for the inverter fault diagnosis. The amplitude and angle of the different mean current vector cluster are used to determine the fault modes. Furthermore, a single data shifting method is introduced to build up an array for the mean current vector calculation in the on line fault diagnosis process. The simulation results verify that, based on the proposed method, the inverter faults can be detected within 1/4 period of fundamental frequency or even shorter time in both speed opened loop and closed loop induction motor drive system.

abstract: An electrical stability analysis of a voltage source inverter fed induction motor drive system is presented assuming an infinite inertia load. With a quasisquare wave scheme this system is characterised as a linear time varying system and its stability is investigated using Liapunov's first method for stability, and also by a Routh Hurwitz technique. The stability of each of the six individual modes is also investigated by evaluating the eigenvalues of the corresponding A matrices. The stability boundaries for the complete drive system are presented for various input filter parameter values.
