Description
Technical field
The utility model relates to a kind of power supply unit, and particularly a kind of have a main power unit and a plurality of secondary power unit power supply unit, and this power supply unit has the circuit design of compiling these secondary power unit outputs.
Background technology
As far as computer, the fluctuation of input electric power will cause the unusual even damage of electronic component start, and therefore normal in order to ensure the running of electronic system (mainly being computer), it is very important that the stable power supply is provided.
And since motherboard change comprehensively adopt the ATX specification after, general power supply unit all need provide the secondary electric power of main electric power and 5V, 3.3V of 12V to computer motherboard and other loads.As shown in Figure 1; A main power unit 91 and two secondary power units 92,93 have been comprised in one power supply unit 9; Certainly the basic electric power modulation circuit such as filtering circuit, power factor correction function device that comprises front end in the power supply unit 9; But circuit such as filtering circuit, power factor correction function device are known by the those of ordinary skill of this technical field, so the detailed circuit of 9 li of this power supply units of repeating no more.This power supply unit 9 has at least one main power output end 910 by these main power unit 91 power supply outputs, and at least one secondary power output end 920,930 of corresponding each secondary power unit 92,93.Wherein this main power output end 910 provides the main output power of 12V, and two secondary power output ends 920,930 provide the secondary output power of 5V, 3.3V respectively.Usually; The secondary output power of 5V, 3.3V all is used for the internal load of supply power supply 9 and keeps the holding state use; But along with popularizing of USB interface; And miniaturized electronics is through the demand of power supply unit 9 power supply, and the secondary electric power of power supply unit 9 also is removed as small-sized load and uses.
TaiWan, China patent certificate I329800 number " standing power supply heat sinking device " for example; This preceding case is all this case applicant and applies for; Disclose a power supply unit and comprised a main electric system and a standing electric system; This main electric system provides main driven by power one radiator fan work, this main electric system to close and standing electric system when still supplying power when starting, this radiator fan is obtained the standing electric power of this standing electric system supply and continued running.
Another preceding case disclose " power supply device that possesses many electric power outputs " No. 200810333 like the TaiWan, China patent that is all this case applicant application, is to disclose a power supply device to comprise rheology always to press the unit be a low-voltage power signal to one second load with the power conversions of importing.
Case such as TaiWan, China patent certificate M296416 number " PC power source supply structure-improved " before one again, wherein should before case back location of disclosing the power supply unit of PC establish a USB socket, this USB socket is connected in the 5V power supply that is transmitted by PC.And a color lamp is connected in through a USB plug on the USB socket of this power supply unit, lights color lamp through this 5V power supply.
This shows that the secondary electricity needs of 5V that power supply unit provides improves constantly,, the demand of electric power is also changed along with the kenel of load develops.The secondary power usage of 5V was little in the past, but along with the specification change of multiple load, and for example the hard disk specification changes 2.5 inches gradually into and is main flow, so the demand of the secondary electric power of 5V improves constantly.Yet the known power source supply is little to the setting capacity of this pair power unit; And the concrete structure of power supply unit only can provide the winding of 12V electric current and 5V electric current in the secondary side setting of transformer usually, and secondary power unit is handled the electric power that forms 3.3V through the electric current of switching 5V through step-down.Along with the demand of 5V constantly promotes, the slump in demand of 3.3V, so the power specification that provides of known power source supply does not meet the demand of client gradually.
The utility model content
Based on the differentiation of load form, and, make the existing power supply mode of power supply unit not be inconsistent customer demand along with the Electric Application mode of the continuous expansion of power supply supply of known technology.Thereby the utility model provides a kind of improved circuit of power supply unit, and reach and change output power specification and capacity effect through changing output circuit framework in the power supply unit, further meet the purpose of client demand and electricity consumption in future trend.
The utility model is a kind of power supply unit, be a power supply unit have a main power unit, at least one by this main power unit power supply main output terminal and a plurality of secondary power unit, by a secondary output terminal of these secondary power units power supplies.This power supply unit is characterised in that these secondary power units respectively have a secondary power transmission line to export secondary electric power; This power supply unit is provided with also that at least one electric power acrossing the line is electrically connected at these secondary power transmission lines and the secondary electric power that compiles different secondary power unit output, and should the pair output terminal electrically connects with a secondary power transmission line wherein and obtain the secondary electric power that compiles.
Further, secondary power unit respectively has a current signal transmission line, and power supply unit comprises at least one current signal acrossing the line of cross-over connection current signal transmission line.
Further, secondary power unit respectively has a voltage signal transmission line, and power supply unit comprises at least one voltage signal acrossing the line of cross-over connection voltage signal transmission line.
Further, to be supplied to the voltage of main output terminal be 12V to the main power unit of power supply unit.
Further, to be supplied to the voltage of secondary output terminal be 5V to the secondary power unit of power supply unit.
Further, the electric power acrossing the line is jumper wire device (jumper) or electric wire or Copper Foil or the silver foil of cross-over connection between two different secondary power transmission lines.
Further, the current signal acrossing the line is jumper wire device or electric wire or Copper Foil or the silver foil of cross-over connection between two different current signal transmission lines.
Further, the voltage signal acrossing the line is jumper wire device or electric wire or Copper Foil or the silver foil of cross-over connection between two different voltage signal transmission lines.
Because the secondary power transmission line of these secondary power units electrically connects through a plurality of electric power acrossing the line each other, the secondary electric power that makes these secondary power units export can pool together and export through single secondary output terminal.Therefore, the secondary power capacity that this pair output terminal can provide obviously promotes, and can meet client demand and the trend of electricity consumption in the future.
