Speed control of induction motor is necessary in engineering applications. To control the speed of induction motor different methods are there. Out of the various methods of controlling induction motors, V/f Control has proven to be the most versatile. To implement the speed control an efficient evaluation board is developed. PWM based speed controlling is carried out. The discrete ON/OFF states of the modulation are used to control the state of the switch(s) which correspondingly control the voltage across or current through the load. The major advantage of this system is the switches are either off and not conducting any current or on and have (ideally) no voltage drop across them. PWM based MOSFET inverter is also designed to deliver the PWM control to the induction motor.
