Referring to Fig. 1, in the utility model embodiment, a kind of blade power supply turns ATX power supply changeover devices, including main power source,
From power supply A, from power supply B, the first NMOS, the 2nd NMOS and the 3rd NMOS, the main power source passes through main power socket connection first
NMOS, 12V turn -12V modules, 12V turn+3.3V modules, 12V turn+5V modules, 12V turn+5VSB modules, 12V turn+22V modules and
Power GOOD circuits, power GOOD circuits are also respectively connected with 12V and turn -12V modules, 12V turn+3.3V modules, 12V turns of+5V
Module, 12V turn+22V modules and ATX power supply output modules, and 12V turns+22V modules and is also respectively connected with the first NMOS, the 2nd NMOS
With the 3rd NMOS, it is defeated that the first NMOS is also respectively connected with hard disk power supply output module, CPU+12V output modules and 2 road PCIE+12V
Go out module, ATX power supply output modules be also respectively connected with that 12V turns -12V modules, 12V turns+3.3V modules, 12V turns+5V modules and
12V turns+5VSB modules, from power supply A by from 3 road PCIE+12V output modules of power outlet A and the 2nd NMOS connections, from power supply
B is by from 3 road PCIE+12V output modules of power outlet B and the 3rd NMOS connections.
Main power source is connected to toggle switch from power supply A and from power supply B.
The operation principle of the utility model is：The main power source portion of blade power supply is taken into 12V, change into 5VSB and 12V change into it is super
The 3.3V and 5V of high current simultaneously provide power good signals, give mainboard ATX power interfaces power supply
Main power source also provides the 12V power supplies of mainboard CPU and 12V and the 5V power supply of hard disk simultaneously
For 1# 2# while from power supply ATX electric power startings, delay exports 12V to video card
The effect of each component below
Blade power input interface:With being inserted into blade power supply, toggle switch is correctly selected, and allow each corresponding power supply
Enforced opening, and export the 12V of big battery
+5VSB:12V is changed into the standby voltages on computer main board, is maintained when power off for battery
Standby processor work
12V turns 3.3/5V:12V is changed into the 3.3V/5V of high current, the high current after normally starting for computer main board
Supply
ATX power output interfaces:Give ATX computer main boards power supply
CPU 12V power supplys:12V power supplys are supplied to the CPU of ATX computer main boards
Hard disk power supply:It powers to the hard disk of computer, mechanical hard disk and electronic hard disc can use
Boost to 22V:The G feet of NMOS must be higher by the power supply of 10V than S foot, and ducting capacity is most strong, in the design
Nmos be switched on and off 12V therefore with 22V bias just effectively open 12V electric currents
- 12V generation circuits:The COMS com for meeting old computer main board make option circuit
High current NOMS:12V high currents are switched on and off
Power good:Delay hair power good are to computer main board, notice computer main board normal work.
Be switched on principle:
1, plug main power source, 1#/2# is from power supply
2, if coupling to correct dial-up, allow each power supply that can export the 12V of high current
After 3, the 12V of main power source have output, 22V circuits and+5VSB circuits can work normally .+5VSB and be powered by ATX
To main board power supply, mainboard will enter standby mode to channel at this time
4, when the power button of computer main board (mainframe box) is pressed, computer main board drags down ATX power cables PS-ON#,
12V turns ATX power conversion boards and opens each road voltage, the 12V's of 12 turns of 5V/3.3V CPU 12V hard disk 5V/12V each group video cards
Power supply is switched on coming,
If 5, Power GOOD detect the 3.3V 5V 12V wholes OK generated below, then postpone 300 milliseconds, then lead to
ATX cables are drawn high to computer main board power good, tell power supply unit each group power supply all OK, and computer main board starts at this time
It is normal to start computer until entering the entire start process of operating system completes
Normal shutdown process
When computer carries out mouse shutdown (long-press cabinet power keys) inside operating system, finished inside computer all
After shutdown process, PS-ON# is to high level for release, and 12V turns ATX+3.3V/+5V/+12V, CPU in ATX power conversion boards
+ the 12V ,+12V/+5V of hard disk, and all video card PCIE 12V power supplys are closed, and normal shutdown process completes
Abnormal shutdown process
When external unexpected power down, when power good circuits detect that+3.3V/5V/12V is abnormal, speed is striven by power
Good signals drag down, and mainboard is perceived after power good drag down, urgent to complete shutdown process, prevent software and hardware by
Damage.
Key Circuit:
High current Dc/Dc:TPS53355 power good generation circuits:TPS3510 22V generation circuits:
LMR64010-12V generation circuits: FR9888
Innovative point:
It supports the mainboard of super high power, therefore does not choose mainboard, rich interface, mainboard of directly plugging into need not external other electricity
Source
Install toggle switch, compatible all blade power supply type additional
All designs make the strong succinct of wiring of autgmentabilities to measure to dig ore deposit
