Induction Motor Speed Control using AC PWM

This project shows that how the speed of an AC
Induction Motor is controlled using Pulse Width
Modulation of AC Mains. In this project the speed of
Induction Motor is controlled in ten discrete steps from
300 RPM to 3000 RPM maximum. Each time when the
control button is pressed, the speed of motor is increased or
decreased by 10%. The speed of the motor is measured
using contact-less TachoMeter.
