Enhanced Electric Propulsion with Space Vector PWM based Induction Motor

Abstract

This paper investigates the application of Space Vector Pulse Width Modulation (SVPWM) for enhanced electric propulsion systems with induction motors. Induction motors are widely used due to their robustness and efficiency, but achieving precise control over speed and torque can be challenging. Traditional scalar control methods have limitations. SVPWM is a sophisticated technique for generating inverter gate pulses that minimizes switching losses and creates a current waveform closer to a sine wave. This research explores the potential of combining SVPWM with scalar control for improved motor performance.

The paper analyzes the principles of induction motor operation and the limitations of scalar control. It then introduces SVPWM and its advantages. The core focus is on the impact of the combined SVPWM-scalar control approach on speed regulation, torque control, and overall drive efficiency. The study also explores practical considerations and potential limitations of this control scheme. The research suggests that SVPWM offers a promising technique for improved electric propulsion. The findings indicate that SVPWM can lead to better overall motor performance, potentially through increased efficiency, improved torque control, or reduced torque ripple. Additionally, the research suggests that SVPWM allows for more precise speed and torque control compared to traditional methods.
