Question

Short note semiconductor controlled drives

Answer 1

The dynamics of motor and load systems are covered. Open-loop andclosed-loop drives are considered, and thyristor, power transistor, andGTO converters are discussed. In-depth coverage is given to ac drives, particularly those fed by voltage and current source inverters and cycloconverters. Full coverage is given to brushless and commutatorless dc drives, including load-commuted synchronous motor drives.
