AC Induction Motor

The ac induction motor is very popular in industrial and consumer applications because of its reliability and low cost. AC induction motors require three PWM signals with sine wave modulation. These signals are generated by the microcontroller. This example circuit uses a three-phase transistor bridge to drive an ac induction motor.
