Abstract

This application relates to the field of voltage control technology and provides a high-precision high-voltage source output device, including: a power supply circuit, a control module, a high-voltage output module, an analog-to-digital converter (ADC), and a digital-to-analog converter (DAC). One end of the power supply circuit is connected to an external power source, and the other end is connected to the ADC, control module, DAC, and high-voltage output module. The high-voltage output module is communicatively connected to the control module via the ADC to transmit voltage signals to the control module; the control module is connected to the high-voltage output module via the DAC to transmit voltage regulation signals to the high-voltage output module. By setting up the ADC and ADC connected to the control module, a closed-loop feedback loop is formed in the output device, and the output is continuously adjusted according to the feedback loop, which can effectively improve the accuracy and stability of the voltage output and reduce output voltage errors.
