Problems solved by technology

[0004] When the existing CELL inspection machine power supply system needs low voltage and high current, the circuit power consumption of the output power channel will increase, the heat generation will increase, and the stability will deteriorate, thus affecting the stability and reliability of the output voltage , and the increase in heat generation requires a huge cooling device, which makes the power system equipment of the CELL inspection machine larger in size and higher in cost

Abstract

An embodiment of the invention discloses a linear voltage-stabilized power supply system and a power supply voltage setting method. In one specific embodiment, the system comprises an MCU control module comprising an MCU controller; a plurality of power supply modules, wherein each power supply module comprises at least one power supply output channel; and a positive voltage power supply module and a negative voltage power supply module which are used for providing power supply voltage for the power supply module, wherein the MCU controller is configured to respond to a required voltage value, sent by an upper computer, of a used power supply output channel and set an output voltage set value corresponding to the power supply output channel, compare the output voltage set values of the used power supply output channels to obtain a maximum value and a minimum value, set a power supply voltage set value of the positive voltage power supply module to be the sum of the maximum value and a fixed voltage value, and set a power supply voltage set value of the negative voltage power supply module to be the sum of the minimum value and the fixed voltage value.

Description

technical field [0001] The invention relates to the field of power supplies, and more specifically, to a linear regulated power supply system and a method for setting the power supply voltage. Background technique [0002] The front cell test of the display panel needs to be powered by an external positive and negative power supply, which has high requirements on the quality of the power supply. Cells of different sizes have different requirements for the voltage and current supplied by the power supply. This requires a wide range of high quality and high power power supply. . [0003] In the course of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] When the existing CELL inspection machine power supply system needs low voltage and high current, the circuit power consumption of the output power channel will increase, the heat generation will increase, and the stability will deteriorate, thus affec...
