This paper highlights the problems associated with single pulse width modulation. In this paper presents a new method to extend the linearity of the sinusoidal pulse width modulation (SPWM) to full range of the pulse dropping region presented. A comparative study with Sinusoidal Pulse Width Modulation Technique is done highlighting the reduction in Total Harmonic Distortion of the output voltage waveform. Adjustable speed drive is an equipment that adjusts speed by external controller. Here, by comparing sine wave and carrier wave SPWM is generated. SPWM inverter produced ac, drives the single-phase induction motor. The control signal is PI controlled and speed is adjusted by changing the load as per requirement. To remove the harmonics produced by SPWM inverter filter is designed.
