Abstract

This paper proposes a fully digitized hardware design scheme of a Space Vector Pulse Width Modulation (SVPWM) based V/f control, which is verified and implemented on a single chip Field Programmable Gate Array (FPGA), for the speed control of three phase induction motor. This is also implemented in Digital Signal Processor (DSP) as FPGA and DSP are the good compromise between the advantage of the flexibility of a programming solution and the efficiency of a specific architecture with a high integration density. These characteristics are quite appropriate for controller design. The comparison of the experimental results especially, Execution time and maximum circuit delay from the DSP and FPGA based implementation respectively, provides guideline on the superiority of FPGA based solution of Industrial Drives in general.
