Design And Development Of Embedded DSP Controllers For Power Electronic Applications

Abstract

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 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.
