Problems solved by technology

In the case of a certain rated power, when the AC power supply voltage is lower than the minimum AC power supply voltage, the switching power supply that handles the AC power supply can still work normally, but the fuse of the electronic equipment system will work in a state that is not designed, resulting in the entire The system is unstable and needs to switch to battery power supply at this time

Embodiment Construction

[0031] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0032] figure 1 It is a structural schematic diagram of the switching control system between AC power supply and battery power supply provided by the specific embodiment of the present invention. see figure 1 , The control system for switching between AC power supply and battery power supply includes: AC power supply 1 , switching power supply 2 , battery 3 , switching control module 4 , and power supply switching module 5 .

[0033] The AC power supply 1 provides AC signals to the switching power supply 2 and the switching control module 4 .

[0034] The switching power supply 2 converts the AC signal provided by the AC power supply 1 into a stable first DC signal, and provides the first DC signal to the power switching module 5 .

[0035] The battery 3 provides the second DC signal to the power...

Abstract

The invention discloses an alternating current power supply and battery power supply switching control system and method. The system comprises an alternating current power supply, a switch power supply, a battery, a switching control module and a power supply switching module. The alternating current power supply is used for providing alternating current signals for the switch power supply and the switching control module. The switch power supply is used for converting the alternating current signals provided by the alternating current power supply into first direct current signals and providing the first direct current signals for the power supply switching module. The battery is used for providing second direct current signals for the power supply switching module. The switching control module is used for collecting and computing effective values of alternating current signals provided by the alternating current power supply and selecting whether battery power supply control signals or alternating current power supply control signals are sent to the power supply switching module according to the effective values. The power supply switching module is used for achieving power supply switching of the first direct current signals and the second direct current signals according to the power supply control signals sent by the switching control module. According to the technical scheme, when alternating current power supply voltage is not stable, reasonable alternating current power supply and battery power supply switching can be achieved, and system design is reliable and reasonable.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a switching control system and method for AC power supply and battery power supply. Background technique [0002] In a dual-power electronic equipment system powered by AC power and battery power, there are usually many ways to switch the power supply. The switching control method using a dedicated power supply chip is: to judge the DC voltage generated by the AC power supply after the switching power supply, when the DC voltage is lost, immediately switch to the battery power supply, otherwise switch to the AC power supply. The switching control method of the single-chip microcomputer to collect the DC voltage is: use the single-chip microcomputer to collect the DC voltage generated by the AC power supply after the switching power supply, and use the software to judge whether to switch to the battery power supply or switch to the AC power supply. [0003] The above...
