Description

The converting structure of redundant formula electric power system

Technical field

The utility model relates to the converting structure of a kind of redundant formula electric power system, is meant that especially the electric power system of a kind of redundant formula is used to the framework that converges whole a plurality of power supply units and integrate output.

Background technology

Known redundant formula electric power system is made of a plurality of power supply unit, power supply unit in this class redundant formula electric power system is adopted the design of sharing mechanism, in other words be exactly the electric power integration backboard that a plurality of power supply units are shared a casing and control usefulness, on practice, usually can be described as the N+M framework, in general, " N " refer to the required sum total power termination of this industrial computer value the power supply unit quantity that should make up, " M " then refers to and can allow power supply unit to damage quantity, with the 2+1 framework is example, constituted by three power supply units exactly, under the situation of 1 an expression tolerable power supply unit damage therein of back, but other power supply unit is normal supply electric power still, certainly according to different demands, the particular design of N+2 framework is arranged also.

Yet the electric power system of existing redundant formula can be with reference to " the spare power supply device structure " of No. the 562163rd, TaiWan, China patent announcement, in the visible box body 10 of the disclosed content of this preceding case, define more than one chute space 14 to locate more than one power supply unit 30, and these a plurality of power supply units 30 are connected on a plurality of connectors 12 on the circuit board 11, but the output power integration that makes a plurality of power supply units 30 is on this circuit board 11 and form redundant formula power supply.

The circuit board 11 described in the case is exactly known " backboard " in the redundant formula power supply in fact before being somebody's turn to do, and the main function of existing backboard is exactly the electric power of a plurality of power supply units of integration, and existing backboard more need possess the function of power conversion, so that the output power of different electric power position standard more than to be provided, yet along with the dimensions of redundant formula electric power system also begins towards compact design style development, therefore except power supply unit out of the ordinary need change size design, this backboard also faced following problem for minification.

First problem is the difficulty that the circuit board size is dwindled, as mentioned above, this backboard has consisted essentially of two big functions of whole electric power of remittance and power conversion, and because power and electric current that remittance is put in order on this backboard are not low, therefore more need provide enough dielectric strength to meet the safety requirement, minification will cause the difficulty that dielectric strength is provided, and circuit unit is withstand voltage need promote with Insulation Specification, take a broad view of, will cause difficult design and cost surging.

Second problem is the difficulty of heat radiation, whole the reaching of converging changed same electric current and power, the less backboard of size is naturally comparatively stood to lose in heat radiation, and large-current electric sub-component size causes the heat-dissipating space of circulation of air narrow and small relatively more greatly, the backboard size is dwindled makes the power density of unit are rise, the ingress of air area dwindles, is provided with radiating subassembly and is difficult for, therefore the less backboard of size can be run into heat radiation and is difficult for, and makes spoilage rise.

And the 3rd problem is that each power supply unit converges whole electric power and needs convert 12V to according to loading demand again, 5V or 3.3V or other voltage level, and existing backboard has been set the rated power and the voltage of change-over circuit when design, so be difficult at the different loading demand rate of doing works and the change of voltage, this problem has also limited the expansion capacity of this redundant formula electric power system, even this redundant formula electric power system allows that the power supply unit of front end expands capacity, but the backboard of rear end still only provides the outlet line and the voltage of fixed qty, and the space that its performance expands is limited.

Therefore, the purpose of this case promptly is to improve above-mentioned technical problem.
