Abstract

The utility model discloses an integrated computer power supply, which comprises a rectifying circuit, a charging circuit, a storage battery, a DC-DC circuit, an adapter circuit and a control circuit; an AC input end is connected with the input end of the rectifying circuit, the output end of the rectifying circuit is connected with the input end of the charging circuit, and branch circuits are arranged at the output end of the charging circuit, wherein one branch circuit is respectively connected with the input end of the storage battery and the input end of the DC-DC circuit through conducting wires and the other branch circuit is connected with the input end of the adapter circuit; the output end of the DC-DC circuit is connected with a main board electricity using circuit in a computer; and the output end of the adapter circuit is connected with the power input end of the peripheral equipment of the computer. Since the storage battery is used to supply power for the internal part of the computer directly through the DC-DC circuit, the utility model ensures that the computer can continuously work after AC power is interrupted and solves the technical problems that the price of the 'uninterrupted power supply' used by the computer system in the prior art is high, the circuit is complex, the fault rate is high and the like.

Description

The integrated computer power supply

Technical field the utility model belongs to computer power supply device technique field, relates to a kind of power supply that can guarantee computing machine continuation operate as normal when alternating current breaks down, especially relates to a kind of integrated computer power supply.

The high-quality computer power supply device of background technology prior art is adjunction between alternating current and computing machine " uninterrupted power source ".Its entire work process is sent alternating current earlier in " uninterrupted power source " exactly, through the rectification circuit rectification, charges a battery through charging circuit, becomes accurate alternating current to send the dc inverter of accumulator through inverter circuit again, gives computer power supply.When alternating current interrupts for some reason, provide inverter circuit required electric energy by the accumulator in " uninterrupted power source ", continue the accurate alternating current of output, to keep the operate as normal of computing machine.But in fact, what the computer-internal circuit used is low-voltage DC, " Switching Power Supply " in the computing machine must be transformed into the accurate alternating current of alternating current or " uninterrupted power source " low-voltage DC and supply with the interlock circuit use, therefore, computer system and do not require that extraneous power supply must be an alternating current.At last need from computing machine, dc inverter with accumulator in comprising the whole power supply exchange process of " uninterrupted power source " is that this step of alternating current is optional, and this a part of technical requirement is the highest just, circuit is the most complicated, cost is the highest, failure rate is the highest.But, " uninterrupted power source " is common apparatus, not only is used for computing machine, and its technical requirement is very extensive, very strict, except voltage, frequency, waveform will also require the phase place of output AC electricity to want strict synchronous with civil power in strict conformity with ac voltage standard.This common apparatus is exclusively used in computer power supply, from the angle of computing machine electricity consumption, requires too much, how high, link is too much, and the cost height is unreasonable.

The summary of the invention the purpose of this utility model is to use " uninterrupted power source " to have problems such as price height, circuit complexity, failure rate height in order to solve the prior art computer system, and a kind of integrated computer power supply is provided.

The scheme that its technical matters that solves the utility model adopts is: it comprises rectification circuit, charging circuit, accumulator, DC-DC circuit, adapter circuit and control circuit; Its main points are: alternating current Ac input end is connected to rectification circuit input end, the output terminal of rectification circuit is connected to the input end of charging circuit, the output terminal of charging circuit is provided with branch road, article one, branch road is connected with the input end of accumulator with the DC-DC circuit respectively by lead, and another branch road is connected with the input end of adapter circuit; The output terminal of DC-DC circuit is connected with motherboard power circuit in the computing machine; The output terminal of adapter circuit links to each other with the computer peripheral power input.

Adapter circuit output standby power supply is in order to also not possessing the computer peripheral that uses the low-voltage DC condition, as uses such as display, printers.When alternating current interrupted, accumulator transferred power supply state to by charged state at once, continued operate as normal to guarantee computing machine.

The beneficial effects of the utility model are: because cancelled inversion part, be the computer-internal circuit supply directly with accumulator through the DC-DC circuit, therefore except guarantee computing machine in alternating current, have no progeny can work on, also have following advantage:

1, the output voltage stabilization of accumulator, pure is the direct supply of high-quality; Directly to the DC-DC circuit supply, the P/C of its power supply quality is than being better than having " uninterrupted power source " of turning traitor the device circuit by it;

2, avoided the loss of " uninterrupted power source " inverter circuit, made the accumulator of same capacity when the same load of carrying, can have the longer support time than " uninterrupted power source ";

3, eliminate the audio noise that " uninterrupted power source " inversion partly produces, improved computer user's working environment;

4, fundamentally eliminated the fault that partly produces by the complicated inversion of uninterrupted power source, reduced because of power issue to the harmful effect that computer system causes, help improving the reliability of computer working;

The utility model has solved the prior art computer system and has used " uninterrupted power source " to have price height, circuit complexity, failure rate high-technology problem.
