The book provides tools for the analysis of electrical machines fed on thyristor converters. A detailed exposition of dc and ac drives is given for making the right choice of drive for a required job to give the desired performances. The aspect of phase controlled converters, inverters, frequency conversion using these converters and the method of improving the line conditions are discussed in detail. Mathematical modelling of both dc and ac motors is given. The aspects of performance of induction and synchronous motors of variable frequency supplies are provided. Also discussed are the features of dc motors operating on converters with respect to commutation, speed range, etc. Methods of improvement in the performance are suggested. A short description of micro-processors in the control of thyristorised ac and dc drives is also includedIt is also possible with a simple diode rectifier and the voltage control obtained in the inverter itself. In these sections only dc to ac converter is discussed in detail. Single Phase Bridge Inverter The schematic diagram of a single phaseanbsp;...
