The through-current capability on its surface, power unit design current value are VIN 40A, VOUT 200A, the VIN and VOUT of power unit it
Between gap width for 2mm, and the gap width that the design of signal section meets between PIN is 1.2mm, and the impedance of signal wire
Meet the requirement of 50ohm, the thickness of entire redundancy plate 2x10 golden finger connectors is done between PIN A2 and A3 in 1.6mm
Notch designs, and the width of notch design is 2mm, is on the one hand to avoid interfering with each other between signal and power supply, the opposing party
Face is to do fool-proof design, puts only redundancy plate 2x10 golden finger connectors and server master board 2x32 connectors are anti-inserted.
The gold-plated length vs' signal PIN foot of power supply PIN foot can be longer, when can guarantee that redundancy plate is inserted into this way, the PIN foot of power supply
Preferentially contacted with motherboard connector, and when redundancy plate removes, signal PIN foot is preferentially detached with motherboard connector, ensure that heat
Plug the reliability of signal.
The PIN foot design of server master board 2x32 connectors is also classified into power unit and signal section, power unit
It is made of GND, VIN, VOUT, signal section is mainly by PWRGD_A, EN_A, ACT_A, VR_HOT#, SVID_CLK_A, SVID_

Each PIN foot of business device mainboard 2x32 connectors does shrapnel design, when redundancy plate 2x10 golden finger connectors are inserted into
During server master board 2x32 connectors, the contact point position of shrapnel can be in redundancy plate 2x10 golden finger connectors most in
Between, it is ensured that the reliability of connection.The through-flow design of PIN foot of the power unit of server master board 2x32 connectors meets each
Gap width between PIN streams 8A, power unit PIN is 2mm, and the design of signal section meets the gap width between PIN
Impedance for 1.2mm, and signal wire meets the requirement of 50ohm, and the width of entire server master board 2x32 connectors is
1.8mm has done jube design between PIN A24 and A25, and the width of jube is 1.6mm.The letter of mainboard 2x32 connectors
ESD protection design is done in number part.
The operation principle of hot plug：The power supply VIN and VOUT of first redundant module are done with server master board by metal-oxide-semiconductor
Isolation design, and the processing of remaining signal is only connect with MCU, such design ensure that when the first redundant module is inserted into
It waits, for connector other than VIN power supplys, remaining signal is in high-impedance state.When the first redundant module is inserted into server master board
When upper, the PIN B32 (TS_A) of server master board 2x32 connectors can be pulled low, and MCU detects the signal and is pulled low it
Afterwards, CTL_VIN_A signals will be sent and is given to the first redundancy template, and the MOS of VIN is controlled to open, VIN power supplys can pass through one later
A LDO chips are converted to the VCC power supplys powered for VR01, when MCU by PIN DTC_VCC_A detect VCC voltages effectively it
Afterwards, the high RST of EN_A can be sent to redundancy plate, redundancy plate VR01 can be worked normally at this time, and output voltage can reach at this time
Vboot voltage values, and the PWRGD signals of VR01 can increase, and after MCU receives PWRGD_A signals, will activate SVID signals, VR_
HOT# signals, the VCCSENSE of far-end feedback, VSSSENSE signals are sent to redundancy plate, treat that redundancy plate output voltage is adjusted to
After voltage required by CPU, MCU can send the MOS that CTL_VOUT_A goes control to export and open, and at the same time sending ACT_A
Signal controls the Health LED of redundancy plate, and indicator light can become green, and the first redundant module of display is working properly.And when the
When one redundancy plate is pulled out, MCU can detect TS_A and be raised, and MCU can will be on corresponding server master board 2x32 connectors
Signal is all set to high-impedance state.Entire hot plug process is controlled by MCU, stablizes fortune which ensures that system
Row.
Fig. 8,9 are please referred to, it is superfluous including first the present invention also provides a kind of electric power system of server CPU redundant powers
Complementary modul block 1, the second redundant module 2, MCU3, CPU4, wherein,
First redundant module 1, the second redundant module 2, for powering for CPU4；
CPU4, for 2 pieces of the first redundant module 1 and the second redundancy mould to be controlled and managed；
MCU3, for the processing of communication data information between CPU4 and the first redundant module 1, the second redundant module 2.
Further, the first redundant module 1 and the second redundant module 2 include power conversion module 11, switching mould
Block 12, health status indicating module 13, current control module 14, wherein,
Power conversion module 11 communicates, and respond for the first redundant module 1 and the second redundant module 2 with CPU4
The instruction that CPU4 is sent；
Switching module 12, when 1 piece of the first redundancy mould and 2 one of redundant module of the second redundant module break down
When, for cutting off contacting between the redundant module and CPU4；
Health status indicating module 13 is used to indicate the working condition of the first redundant module 1 and the second redundant module 2；
Current control module 14, for controlling the load balancing of the first redundant module 1 and the second redundant module 2.
Specifically, power conversion module 11 is mainly by power conversion chip VR01 and periphery circuit, input capacitance, power
The compositions such as MOS, outputting inductance, output capacitance, major function be with CPU normal communications, and real-time response CPU send finger
It enables, generates the power supply of the stabilization of cpu demand.The defencive function that the module possesses includes UVP (low-voltage variation), and OVP (protect by overvoltage
Shield), OCP (overcurrent protection), OTP (overheat protector), UVLO (under-voltage protection), SCP (short-circuit protection).In addition, power supply converts core

Repair, and faulty redundant module can be replaced in time.Its status indicator lamp uses bi-colour light, when redundant module works normally
When, indicator light is shown in green, and when redundant module operation irregularity, indicator light is shown as yellow.Staff can be according to spy
The indicator light put is positioned to judge the working condition of redundant module.
Current control module 14 is primarily to ensure load balancing between each redundant module.First redundant module and
There is a sharing control bus between two redundant modules and MCU, main function is the current reference as current control module.
MCU can read power conversion chip VR01 in real time and power conversion chip VR02 feeds back to the current information of CPU, then by 2
A current value does average value operation, and the result of operation subsequently is sent to each current control module by sharing control bus
14, and its current information with detecting real-time can be compared after current control module 14 receives the current information, if
When the electric current of detecting real-time is less than normal, current control module can feed back to die terminals, thus by the way that output voltage is turned up, it is defeated to realize
Go out the increase of electric current.If the electric current of detecting real-time on the contrary is bigger than normal, chip is fed back to by current control module, by output voltage
It turns down, to reach the purpose for reducing output current.So as to reach the Load Balance Design of redundant module.
In addition, in order to ensure the convenience of server admin personnel's maintenance work, while ensure what server system was stablized
It runs and is unlikely to interrupt, the first redundant module 1 and the second redundant module 2 have done the design for supporting hot plug, below with the
It is illustrated for one redundant module 1, the PIN foot design of the redundancy plate 2x10 golden finger connectors of the first redundant module is divided into
