Abstract

The invention discloses a control method, device and system of power supply voltage. The method comprises the following steps: receiving a power supply signal; converting the voltage of the power supply signal to obtained a converted power supply signal, wherein a digital potentiometer controls a power supply conversion chip to convert the voltage of the power supply signal; and outputting the converted power supply signal. The technical problem that a high-precision requirement on the voltage by precise equipment cannot be satisfied since the adjusting precision on the power supply voltage islow in the related technology is solved.

Description

technical field [0001] The present invention relates to the field of power supply voltage control, in particular, to a control method, device and system for power supply voltage. Background technique [0002] Some precision equipment with variable input voltage have high requirements for power supply, and ordinary potentiometers cannot meet the high precision requirements of equipment voltage. [0003] For the above problems, no effective solution has been proposed yet. Contents of the invention [0004] Embodiments of the present invention provide a power supply voltage control method, device, and system to at least solve the technical problem in the related art that the adjustment accuracy of the power supply voltage is not high and cannot meet the requirements of precision equipment for high precision voltage. [0005] According to an aspect of an embodiment of the present invention, a power supply control method is provided, including: receiving a power supply signal;...
