摘　　要：介绍一种基于FPGA的可编程电压源系统的设计与实现。采用FPGA为控制芯片，应用QuartusⅡ软件和硬件描述语言为工具，通过数／模转换和运放把数字信号转换成模拟电压信号。实验表明，该系统操作灵活方便，稳定性强，调压精度高，电压可调范围大（0-26V），具有很好的实用性和工程参考价值。A design of programmable voltage source system based on FPGA is introduced. FPGA is used for the control chip. The application of Quartus Ⅱ software and hardware description language, by the DAC and OPA, the digital signal is converted into the analog voltage signal. The results indicate that the system can be simply operated and runs stably. The output voltage is precise and the adjust range of the voltage can achieve 0-26V. The system has a very good reference for practical and engineering.
