Abstract:
The accurate and versatile control of a direct current machine's speed using a thyristor converter has led to its use for many industrial applications. However, as will be demonstrated, the current gain characteristic of such a device is not linear and under certain operating conditions can lead to an unacceptable degradation in performance. In order to develop a method of adaptive control that can compensate for the gain changes, the key features and theory of phase controlled thyristor converters are described and used to develop a digital computer simulation of a single phase converter.

Mathematical studies are performed to assess the optimum characteristics of these materials, such that inrush current is suitably controlled for a minimum s

The principle of operation dictates that the output of a cycloconverter contains some harmonics. For drive applications, the harmonics at best increase losses in the motor and may well cause instability. Various methods of analysing the output waveform have been considered. A Fortran 77 program employing a modified Fourier series, making use of the fact that the input waveforms are sinusoidal, was used to compute the individual harmonic amplitudes. A six pulse three phase to single phase cycloconverter was built and a Z-80 microprocessor was used for the control of firing angles. Phase locked

Abstract:
This thesis deals with modeling, simulation and implementation of Load Commutated SCR based current source Inverter (LCI) fed squirrel cage induction motor drive with sinusoidal voltage and sinusoidal current. In the proposed system, the induction motor is fed by an LCI. A three level diode clamped voltage source inverter (VSI) is connected at the motor terminal with ac chokes connected in series with it. The VSI currents are controlled in such a manner that it injects the reactive current demanded by the induction motor and the LCI for successful commutation of the SCRs in the LCI. Additional
