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.
