Reversible Drives using Phase Controlled Converters: When speed control in both forward and reverse directions is required a Reversible Drives is used. In several applications the speed reversal may be…
Performance of DC Motors Operating on Phase Controlled Converters: The nature of the output voltage and output current of a phase controlled converters impains the performance of the dc motor…
Three Phase Synchronous Motor Fed From Cycloconverter: DC link converter is a two stage conversion device which provides a variable voltage, variable frequency supply. Variable voltage, variable frequency supÂply can…
Cycloconverter Feeding Three Phase Induction Motor Drive: Variable frequency supply to an induction motor may be obtained by using a cycloconverter. As has already been discussed, a cycloconverter is a…
Cycloconverter: A variable frequency supply for feeding a three phase motor can be obtained from a cycloconverter which operates on a 50 Hz supply and provides a variable frequency supply…
Selection of Ratings of Devices of a Chopper Converter: Chopper Converter - The waveforms of currents and voltages are useful in deciding the ratings of devices. The main thyristor carries…
Four Quadrants Converters: Four Quadrants Converters - The converters described in the previous sections are suitable either for one quadrant or two quadrant operation. In the former case stepless speed…
Sequence control of Converters: Sequence control of Converters - We have shown that fully controlled converters take lagging reactive power from the mains. This requirement is less in half controlled…
