This paper presents the hardware implementation of V/f control of induction motor using sine wave PWM method. Because of its simplicity, the V/F control also called as the scalar control, is the most widely used speed control method in the industrial applications. In this method the ratio between stator voltage to frequency is maintained constant so that the stator flux is maintained constant. As the stator flux is maintained constant, the torque developed by the motor depends only on the slip speed and is independent of the supply frequency. Thus we can control the speed and torque of induction motor by simply controlling the slip speed of induction motor. The complete control is achieved with the help of TMS320F28027 Development Board. One of the basic requirements of this scheme is the PWM inverter. The gating signals are generated using sine wave PWM technique. Implementation issues such as PWM signal generation, ramp control, v/f control, inverter design are discussed. The results are discussed based on the various waveforms.
