Fast PWM signals simulation and generation system for investigation and education

Abstract

Frequently, in investigation, teaching and other environments, it becomes a must to have multiple Pulse Width Modulation (PWM) methods for power inverter systems. Usually, we dispose only one or two possibilities of achievement with many difficulties to change the work environment since normally it involves changes in the circuitry and in the programmable elements. This work describes the achievement of a system that unifies the circuitry around a single microcontroller system and a PC supervisory, where there are different available algorithms of PWM modulation already developed.
