Intelligent control joint control power switch

Abstract

The invention relates to an intelligent control and joint control power switch, applied to an electronic device. The power switch comprises a driving module, a NOT gate module, a bistable module and adelay module, wherein the driving module is configured to compare a signal power output by a backbone circuit with a first reference power, output a high level when the signal power is greater than the first reference power, and output a low level when the signal power is less than the first reference power; the NOT gate module is configured to compare the amplified signal power output by the backbone circuit with a second reference power, output a low level when the signal power is greater than the second reference power, and output a high level when the signal power is less than the secondreference power; two input ends of the bistable module are separately and electrically connected with the output end of the driving module and the output end of the NOT gate module, and two output ends of the bistable module are coupled with the delay module; the delay module is configured to perform corresponding processing according to the existence or absence of logic output signals; and when the delay module does not receive the logic output signals, delay processing is carried out. The power switch is simple to operate, and has the advantages of ensuring stronger safety, saving electricity and prolonging the service life of the electronic device.

Description

technical field [0001] The invention relates to a switching power supply, in particular to an intelligent control joint control power switch applied to various electronic devices, especially to desktop computers and televisions. Background technique [0002] Switching mode power supplies are widely used to provide voltage in applications such as televisions, desktop computers, self-supporting power adapters, etc. Most of the existing switching power supplies have the technical problem of high standby energy consumption. For example, after the computer system is shut down, for the purpose of saving energy, preventing electrical fires and prolonging the life of the equipment, the existing AC power control device for the desktop computer system can be installed on the computer. After the main unit shuts down, the AC power supply of the peripherals of the computer is automatically turned off. There are some defects in the existing AC power control device: 1. There is no voltage...

AI Technical Summary

Problems solved by technology

There are some defects in the existing AC power control device: 1. The main circuit has no voltage transformation, and it is easy to generate heat; The output waveform of some diode detection current methods is easy to change, which has an impact on the life of electrical appliances

Although this technology solves some power consumption problems, its structure is complex and the effect is not good, and the power module cannot solve the corresponding technical problems of other electronic devices
