Abstract

The invention discloses a method and a device of accurately controlling voltage. In the method of accurately controlling voltage of the invention, a voltage control logic component, a D/A converter, a voltage generation circuit and an A/D converter are arranged to process real time adjustment to an output voltage on a working component so as to realize the accurate control of the output voltage on the working component. The aim of adopting the set is to combine the digital television with the analog television to accurately adjust the real time voltage on the working component so as to solve the problem that the big error between the ideal voltage and the real voltage which is generated by using the voltage generation module or circuit in the prior art.

Description

technical field [0001] The invention relates to the field of circuit control, and more specifically, the invention relates to a method and device for precisely controlling voltage. Background technique [0002] In the current circuit control technology, a voltage generating module or circuit is usually used to generate voltage, but due to the accuracy of circuit devices, there is a large error between the actual voltage generated by the voltage generating module or circuit and the ideal voltage. Especially, for fields with higher voltage precision requirements, the current voltage control technology cannot meet the requirements of these fields. [0003] Among these fields that require high voltage precision, the field of digital printing is one of them. Digital printing technology is a non-contact printing technology developed rapidly in recent years. It directly processes, transmits and prints image data. Digital printing technology is called non-contact printing because ...
