The power supply system of the invention can realize concentrative power supply and solve the difficult problems in the power supply of frame-typed network servers which are currently deployed in large scale, thus having extremely good promotional and practical values.
Description
Technical field
The present invention relates to a kind of Computer Applied Technology field, specifically a kind of large power server machine cabinet redundancy electric power supply system.
Background technology
At present industry is in the solution that realizes that redundancy adopted, be utilize the diode of power supply inside come by or door output to drive load.But the effect of doing like this is to cause the diode voltage pressure drop big, thereby make that the thermal losses power of generation was bigger when the electric current that flows through this diode increased.Industry is for solving diode forward pressure drop that exists and the thermal losses that brings thereof, in the application of low-voltage, high electric current, do not adopt diode in the configuration, but adopt low-loss field effect transistor M OSFET ORing technology, adopt this mode can alleviate the too high problem of loss to a certain extent.But the further analysis through us is found, adopts MOSFSET controller itself highly integrated and the discrete design also to have a lot of weak points, still has big voltage loss to a certain degree.
Summary of the invention
The purpose of this invention is to provide a kind of low-power consumption and safe and reliable large power server machine cabinet redundancy electric power supply system.
Purpose technical scheme of the present invention realizes in the following manner, adopts integrated circuit TPS2410 controller and MOSFSET ORing collocation can be equivalent to a diode, realizes Redundancy Design, has solved above-mentioned existing problem so fully.
Particular circuit configurations is as shown in drawings: electric power system is made up of power module and power supply redundancy stabilizator, wherein power module be will input the 220V electric main after rectification, filtering, convert the 48V direct current to, contact respectively power supply redundancy stabilizator and by hot-swappable interface and rack load and connect of the power output end of one or more power module.
The power supply redundancy stabilizator is made up of integrated circuit (IC) and field effect transistor MOSFET, and the S of field effect transistor MOSFET, D, G pin are connected with the Gate pin with A, the C of IC respectively, wherein the V of integrated circuit (IC)
DDPin and C pin and the D utmost point that meets field effect transistor MOSFET connect load as redundancy.
Of the present inventionly with excellent effect be the differential voltage V at field effect transistor MOSFSET D, C two ends
ACBy controller IC monitoring, controller IC is the gate voltage that field effect transistor MOSFET is set according to VAC.The actual switch point voltage when field effect transistor MOSFET opening and closing and the method for control and speed have determined the controller IC successfully performance and the stability of simulating diode.Owing to adopted of the present invention relating to, stable high-power electric current is provided for the rack webserver, and can evades when the inverse current situation generation that inefficacy power supply (failedpower supply) occurs.Also effectively reduced simultaneously the energy loss that pipe causes because of heating.
Description of drawings
Accompanying drawing 1 is the structural representation of machine cabinet redundancy power supply.
According to the redundant power of N+1 configuration, the necessary number of expansion of power supply promptly can be realized the N+1 redundancy.
Embodiment
Adopt machine cabinet redundancy power supply technique of the present invention, can realize the power supply hot-plugging technology, also be to utilize this controller that the hot-swappable incident between power supply and the power bus is managed, promptly no matter what state power supply and bus are in, power supply can hot plug to power bus.When power supply from power bus during hot drawing, it is 0 volt that controller can transfer to the voltage of MOSFET input end, thereby as much as possible exposed connector pinout voltage is reduced to safe range.Hot-swapping controller can effectively be managed surge current and bring into play the effect of high speed circuit isolating switch under stable status, with the protection system assembly.
The concentrated redundancy electric power supply system that arrives involved in the present invention can be realized
(1) exchanges commentaries on classics direct current (AC-DC) module, also has powerful conversion demand, owing to be to power to the rack webserver, therefore consider a little more at design aspects such as high-power, reliability, stability, can easily realize the high-power output demand that 10000W is above, thereby satisfy the power demands of the rack webserver of whole rack configuration.
The physical dimension aspect is applicable to 19 inches racks of industrywide standard, highly has only 2U, can put into maximum four power supply units simultaneously, each power supply unit can independently carry out the translation function of AC-to DC, and with the civil power redundancy feature, promptly each unit can connect the electric main of input independently.Can fully guarantee the reliability and stability (redundancy of civil power, alternating current are to the conversion of direct current AC-DC) of supply module like this, thereby meet the reliability requirement of the rack webserver crucial Processing tasks.
(2) load balancing module, this module mainly act on and provide the load-balancing function that changes direct current (AC-DC) module to exchanging.Because the power supply unit of above-mentioned " exchanging changes direct current (AC-DC) module " the inside of introducing has the independence of isolation, therefore must power supply unit be coupled together by a module, load-balancing function is provided, thereby realizes the load-balancing function of each power supply unit.And this load balancing module plays this effect exactly.By a series of peripheral circuit design (1) being exchanged commentaries on classics direct current (AC-DC) module couples together by the power management bus.Thereby realization load-balancing function.
(3) isolation module solves exactly and evades in when debugging wiring or maintenance process the problem that human body is constituted significant threat and takes place.
Involved in the present invention to isolation module adopts is bridge, as the term suggests in communication, play the bridge effect exactly.Concrete effect is exactly when centralized wiring, substitutes the effect of copper bar, that is to say the effect of playing bus-bar.
(4) load blocks is exactly the rack webserver of terminal, and they adopt direct current-48v input.
(5) exchange expansion module, the equipment of the power supply for exchange of network is provided for exactly the rack network server, be meant mainly that in native system exchanging insert row is integrated in the rack, the terminal of 5 ac plugs is provided, one is switch, and other four is the power supply unit that (1) exchanges changes in direct current (AC-DC) module.
