Testing and hardware implementation of SPWM inverter using TMSF28335eZDSP

摘要

This paper presents testing and implementation of two pulse width modulation schemes i.e. bipolar sinusoidal pulse width modulation (SPWM) technique and unipolar SPWM technique for a single phase H-bridge inverter that is commonly used to regulate the magnitude and frequency of the inverter's output voltage. Both the schemes were implemented on the inverter system and total harmonic distortion (THD) for the scheme was analyzed. The schemes were simulated using PSpice/Orcad platform and the validation in real time was done using F28335eZDSP.
