DSP controlled DC/DC boost converter for renewable/green power applications

Increasing energy demands and global rising pollution awareness resulted much of the research work to focus on green power technologies. Fuel cell based distributed generation is considered as one of the most promising devices due to their major advantages of higher efficiency, cleanliness, modularity and eco friendly nature. In multi stage power electronic interface, common DC distribution and hybrid systems the deployment of boost converter plays a vital role to reduce the operating current level with increased DC link voltage. The development of control scheme using analog circuits is more complex due to more component counts and their performance totally depends on the accuracy of each component. However, in the present scenario development of digital technology plays a significant role due to their advantages of higher fast and compactness. Therefore, in this work a low cost TMS320F2812 DSP controller is used to generate the firing pulse interfaced with MATLAB/Simulink model in Real Time Workshop to regulate the boost converter output voltage for varying load.
