Gate Firing Converters: The firing pulse control unit constitutes the heart of any thyristor power conÂverter. The Gate Firing Converters required by the thyristors are often derived from the digital…
Control System Performance: From the foregoing discussion on control systems it can be seen that the beÂhaviour of the control systems can be specified, based on several time domain specifications.…
Closed Loop Control of DC Motor: Closed Loop Control of DC Motor - The dynamic behaviour of a system is described by a set of differential equaÂtions. On many occasions…
Three Phase Drives: Single phase drives discussed in the previous section are employed for low and medium powers. When the power of the drive is very large the three-phase converter…
Commutation in DC Motor: Commutation and commutator wear and tear of the dc motor must be given due consideration when the motor operates on solid state converters. Spark-less commutation must…
Field Oriented Control of Induction Motor: In the slip controlled drives using VSI or CSI discussed in the foregoing secÂtions, the stator voltage or stator current is controlled using slip…
Current Source Inverter Fed Induction Motor Drive: Current Source Inverter Fed Induction Motor Drive - In a voltage source inverter fed induction motor the applied voltage to the stator is…
Speed Control of Variable Frequency Induction Motor: Speed Control of Variable Frequency Induction Motor of a squirrel cage induction motor can be controlled very effectively by varying the stator frequency.…
