Mathematical modelling of sinusoidal pulse width modulated signal and its implementation on microcontroller based embedded system

Abstract

This paper presents the mathematical model of a variable frequency variable voltage sinusoidal pulse width modulated (SPWM) signal and implementation of the same on microcontroller based embedded system. The mathematical model is based on the step function. The implementation of the mathematical model on P89LPC9221 microcontroller based embedded system is described. The analysis is validated by simulation and experiment results.
