Integrating System Functions Using a Single DSP Controller

Digital signal controllers provide the unique combination of on-chip peripherals and computational power needed to implement motor control applications that range from aerospace, automobiles, medical, robotics, manufacturing, to home appliances. A system based on a single-chip digital controller allows designers to implement multiple functions such as a general motor drive algorithm, power factor correction scheme, and communications protocol etc. needed for overall motor drive systems. In addition to motor control, these controllers also integrate various analog modules to simplify overall system design. These digital controllers can be used as universal hardware platforms for motor drive applications. This reduces the overall system cost and also shortens the time to market. This paper presents a complete implementation of a three-phase PMSM drive and highlights the advantages of analog integration and how to comply with various international standards like IEC- 60730.
