A noise control system and method

Abstract

The invention discloses a noise control system and its method, comprising a control module, a power supply module and a voltage output module, the power supply module including a voltage command receiving module, a voltage level processing module and a switch control module; the control module is used for controlling the power supply module to adjust the output voltage; the voltage output module is used to output voltage; the voltage instruction receiving module is used to receive the voltage adjustment instruction of the control module; the voltage level processing module is used to judge Whether the target voltage adjusted by the voltage adjustment instruction is higher than the current voltage level; the switch control module is used to adjust the voltage according to the voltage adjustment instruction. Adopt a kind of noise control system and its method of the present invention, through the improvement of digital power supply part and analog power supply part, through mutual cooperation with control module, operating system and BIOS, eliminate the noise problem caused by CPU voltage switching .

Description

technical field [0001] The invention relates to the control field, in particular to a noise control system and method. Background technique [0002] At present, in intelligent electronic devices such as notebook computers and desktop computers, when the operating system is turned on, shut down, enters and exits hibernation or sleep, etc., due to the frequent voltage conversion of the CPU, there will be obvious electronic noise on the ceramic capacitor of the CPU power module. . In the prior art, it is usually adopted to reduce the voltage conversion rate of the intel platform and to improve the generation of noise by adding capacitors or other hardware methods, and to reduce the noise by reducing the switching time of the CPU digital power supply voltage; The reduction is very limited, and the improvement effect is better for scenes such as standby or playing movies under the operating system, but basically no improvement effect for situations such as booting, shutting down...
