Realization of SV-PWM Motor Control Algorithm using ARM Cortex-M4 Based Microcontroller

Abstract

Space vector pulse width modulation (SV-PWM), which is the one of the sensorless control techniques of the permanent magnet AC motors, is preferred because it provides voltage and frequency control and produces less harmonics than the sinusoidal pulse width modulation (S-PWM) technique, respectively. In SV-PWM method; the fact that results of the complex equations should be performed in a given period of time by the microcontroller to calculate the required switching time, makes it difficult to implement algorithm in practice. This study includes the implementation of SV-PWM algorithm using ARM Cortex-M4 based microcontroller and experiments conducted on a motor.
