本设计提出了一个基于FPGA的程控稳压电源的方案。通过按键向FPGA输入信号，FPGA得到“十位”和“各位”计数脉冲信号，通过计数器模块计数，内部计数器的信号一路送给外部显示电路来显示当前的电压值，另一路经过D/A转换器（DAC0832）输出模拟量，再经过运算放大器隔离放大，控制输出功率管的基极，随着功率管基极电压的变化而输出不同的电压，同时实现双路输出。实际测试结果表明，本系统具有易调节，高可靠性，操作方便，电压稳定度高，其输出电压采用了数字显示的特点。-This design presents an FPGA-based programmable power supply solution. Input signal to FPGA, FPGA get　ten　and　you,　the count pulse signal, counting by the counter module, the internal counter signal all the way to an external display circuit to display the current voltage value, the other way through the D/A conversion through the key device (DAC0832) analog output, through the operational amplifier isolation amplifier, control the output power tube base, with the power transistor base voltage changes and different voltage output, while achieving dual output. The test results show that the system has easy to adjust, high reliability, easy operation, high voltage stability, the output voltage using the features of a digital display.
