Abstract
The utility model discloses a computer power supply, including high -pressure filter capacitance, active circuit, second grade filtering and driving transformer, one -level filtering one side is provided with PCB, high pressure filter capacitance one side is provided with main transformer, and support body one side is provided with the fan, fan one side is provided with power socket, the power socket lower extreme is provided with the switch. Beneficial effect lies in: small light in weight, owing to there is not frequency transformer, so volume and weight have only linear power supply's 20%-30%, the consumption is little, and is efficient, and the consumption on the transistor is little, and it is efficient to change.
Description
Technical field
The utility model belongs to computer fittings field, is specifically related to a kind of computer power supply.
Background technology
Computer belongs to light current product, that is to say that the operating voltage of parts is lower, generally at positive and negative 12 voltsIn, and be direct current. And common civil power is 220 volts of alternating currents, can not be directly at machine elementUpper use. Therefore computer is the same with a lot of household electrical appliances needs a power unit, is responsible for common civil power conversionFor the operable voltage of computer, be generally arranged on computer-internal. The core component work electricity of computerPress very low, and because computer operation frequency is very high, therefore higher to the requirement of power supply. At presentThe power supply of computer is on-off circuit, transfers common alternating current to direct current, then by copped wave control voltage,Different voltage is exported to respectively to the machine elements such as mainboard, hard disk, CD-ROM drive, but present calculatingSometimes also there is the phenomenon of damaging mainboard, hard disk in electromechanical source, thereby has affected the life-span of computer.
Utility model content
The purpose of this utility model is just to provide in order to address the above problem a kind of computer power supply.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of computer power supply, comprises high-voltage filtering capacitor, active circuit, secondary filter and driving transformationDevice, one-level filtering one side is provided with PCB, and described high-voltage filtering capacitor one side is provided with main transformer, support bodyOne side is provided with fan, and described fan one side is provided with outlet, and described outlet lower end is provided with outClose.
In order further to improve the result of use of computer power supply: described fan is fixed on described support body one side,Described outlet is fixed by screws on described support body.
In order further to improve the result of use of computer power supply: described high-voltage filtering capacitor is embedded in describedOn body, described secondary filter is fixed on described support body.
In order further to improve the result of use of computer power supply: described driving transformer is connected with described support bodyConnect.
The beneficial effects of the utility model are: volume is little lightweight, owing to there is no Industrial Frequency Transformer, soVolume and weight only has 20%～30% of linear power supply, and power consumption is little, and efficiency is high, and the power consumption on transistor is little,Transformation efficiency is high.

Detailed description of the invention
For the ease of understanding the utility model, below with reference to relevant drawings, the utility model is carried out more comprehensivelyDescription. In accompanying drawing, provide preferred embodiment of the present utility model. But the utility model can be withMany different forms realize, and are not limited to embodiment described herein.
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As Figure 1-Figure 2, a kind of computer power supply, comprise high-voltage filtering capacitor 1, active circuit 2,Secondary filter 3 and driving transformer 5, one-level filtering 4 one sides are provided with PCB6, described high-voltage filtering capacitor1 one sides are provided with main transformer 7, and support body 11 1 sides are provided with fan 8, and described fan 8 one sides are provided with electricitySource socket 9, described outlet 9 lower ends are provided with switch 10.
In said structure, when civil power enters after power supply, first remove by choking-winding and high-voltage filtering capacitor 1High frequency clutter and interfering signal, then obtain HVDC through over commutation, one-level filtering 4 and secondary filter 3Electricity. Then by switch 10, high voltage direct current is changed into dither direct current, then fall by main transformer 7Press. Last filtering high-frequency ac part, so last output is for the relatively pure low-voltage direct of computerElectricity.
In order further to improve the result of use of computer power supply: fan 8 fixing bracket body 11 1 sides, power plugMouth 9 is fixed by screws on support body 11, and high-voltage filtering capacitor 1 is embedded on support body 11, secondary filter 3Be fixed on support body 11, driving transformer 5 is connected with support body 11.
More than show and described general principle of the present utility model, principal character and advantage. The skill of the industryArt personnel should understand, and the utility model is not restricted to the described embodiments, in above-described embodiment and descriptionThat describes just illustrates principle of the present utility model, do not departing under the prerequisite of the utility model spirit and scope,The utility model also has various changes and modifications, and these changes and improvements all fall into this claimed practicalityIn novel scope. The claimed scope of the utility model is defined by appending claims and effect thing thereof.
