The Research on Variable Frequency Speed-Adjusting System Based on SOPC
Variable frequency speed-adjusting system changes the speed of the implements by adjusting the stators voltage and frequency. The characteristics such as energy saving, high efficiency, wide adjusting range, excellent static and dynamic performance make it become a high-performance AC speed-adjusting method. In this paper, we have researched the SOPCbased variable frequency speed-adjusting system, including its design principle and application. This paper also has customized an embedded IP core and has transplanted the Nios II soft core to a FPGA successfully. Besides, the FPGA-based control circuits and IPM driving circuits, the designs of which are proved reliable and correct, are implemented in this paper. Finally, this system has been tested on the experiment platform designed by us. It works stably in the on-load and off load experiments, which indicates that the original design purpose is achieved.
