摘要

Space vector PWM Inverter fed volt/Hz induction motor drives are well accepted for many industrial applications. There are numbers of work, reported in literature on implementation of space vector PWM technique using DSP, FPGA and high-end 16-bit microcontrollers. But the use of costly resources restricts their application in industrial fan, blower, air-condition & ventilation system etc. In this work a state-of-the-art algorithm has been developed to implement Space vector PWM technique for Volt/Hz induction motor drive using a popular 8-bit microcontroller to reduce the overall cost and complexity of the drive. The possible limitations of the controller have been conquered by implementing innovative ideas and techniques for calculation of switching time and selection of switching states. The execution time of the program is also reduced by developing a special algorithm for division, multiplication and ¿¿¿sin¿¿¿ function involved in the calculations. A prototype has been developed to test the effectiveness of the algorithm and satisfactory responses are found.
