A New Power Electronic Control System featuring 32-bit Microcontroller and FPGA

摘要

This paper presents a new power electronic control system comprised of the 32-bit TriCon microcontroller-board and a Xilinx XC2V500 FPGA. The system is intended for use in application with fast signal transition and many analog measures to be controlled. Configuration of FPGA modules implemented in VHDL can be realised by means of a parallel interface between microcontroller and FPGA. The proposed system allows for fast control, signal manipulation and error management. It is shown that modules implemented in the FPGA can extend the peripherals of the microcontroller and offload from time-critical processes. Hence a system with higher performance and more flexibility is obtained.
