DESIGN AND DEVELOPMENT OF EMBEDDED DSP CONTROLLERS FOR POWER ELECTRONIC APPLICATIONS by RAMAN NAIR HARISH

ii ACKNOWLEDGEMENTS I am extremely grateful to my supervising professor Dr Babak Fahimi for his unstinted support. His guidance and encouragement has been vital in my learning process. I am thankful for his confidence in me and mentoring me for the successful completion of this thesis. I would like to express my gratitude to my parents and sisters for their unbounded care and love. Their encouragement was extremely valuable to me. Furthermore I am thankful to Dr Rasool Kenarangui and Dr Wei-Jen Lee for willing to be on my supervising committee. I would also like acknowledge my friend Pallavi for her time and valuable feedback. My appreciation also extends to Ranjit, Mahesh and other members of PECM Power applications like motor drives, inverters have complex algorithms that can be used to improve their efficiency. More often reduced manufacturing cost takes precedence over better efficiency. DSPs with their high computational power can provide reduced cost and higher efficiency. Though the cost of a standalone DSP chip has reduced, its integration to form a complete embedded product is an area often overlooked. High frequency of operation, reduced package size, and sensitivity to iv component placement are some of the factors that affect the interface between input/output devices and the DSP. This thesis presents the design and development of an embedded DSP controller board using TI's TMS320F2808. A three phase Space Vector PWM inverter is constructed and used to test the DSP board. This thesis also compares Space Vector PWM with other carrier based modulation schemes.
