drives- fixed frequency/variable frequency/current control- V/F control using PIC microcontroller- vector
control using embedded processors
TOTAL: 45 PERIODS
OUTCOMES:
On the completion of the course, the students will be able to
 realizethe working of PWM converters.
 design a dc motor and to apply control techniques for the application.
 obtain knowledge on the operation of Induction motor drives and to analyze its performance.
 realize the speed control using V/f and vector control techniques for an induction motor.
 generate the firing pulses for the converters and apply control algorithms to obtain the desired
characteristics.
