Abstract
This study demonstrates, the generation of triggering signals using SPWM technique for a seven level H-Bridge cascaded inverter with the help of MATLAB-DSP (ezDSP 28335) interfacing without using EPWM block and presents the final output of the inverter. The focus is mainly on hardware implementation of Cascaded H-Bridge MLI using MATLAB-DSP interfacing. Generation of triggering signals using MATLAB-DSP interfacing has been explained briefly. Use of GPIO block in SIMULINK model makes the triggering signal generation easier and more efficient. The switching control signals required for triggering of switches are generated using MATLAB-DSP (ezDSP 28335) interfacing. This approach exploits the advantages of block programming in SIMULINK.
