| Summary: | It proposed an implementation method of digital filter based on FPGA and analysed its principle. Filter kernel is realized by adding module, multiplication module and limit truncation module, and then the concept of module reuse is proposed to realize mutlichannel filter with limited FPGA resources and encapsulate the input output data bus and kernel in one module. Using FDATOOL module to design filter parameters and VHDL to write digital filter running on a Xilinx Spartan6 FPGA platform, the actual effect was verified by setting the FPGA as DSP peripheral. The method has been successfully applied to a variety of power electronic grid-connected inverters and achieved good results. |
