Description
Technical field
The utility model relates to a kind of novel power distribution board.
Background technology
The operating characteristic of server determines that it is very high to reliability requirement, when emergency power off, can also maintain the normal operation of server.Therefore, redundant power becomes the common configuration of server.
At present conventional power distribution board, uses two pieces of identical power supply backplanes to realize for subsequent use of power supply, every block power supply plate is all provided with 12v and 12v_standby input, voltage conversion circuit, 12v, 5V, 3V3 output.
But such configuration, deposits the waste of redundancy in design and cost.
Summary of the invention
The technical problems to be solved in the utility model is: in order to solve the problem, and optimizes the design of original stand-by power supply distribution plate, saves design time and cost.
The technical scheme that the utility model adopts is:
A kind of novel power distribution board, described power distribution board comprises main power board and standby electricity source plate, main power board is provided with 12v and 12v_standby input, voltage conversion circuit, 12v, 5V, 3V3 output, wherein, described standby electricity source plate is provided with 12v and 12v_standby input, and standby electricity source plate is wired to the voltage conversion circuit input of main power board, exports 12v, 5V, 3V3 are for mainboard.
Described voltage conversion circuit can be power conversion chip.By transforming circuit or pressurizer etc., be 5V or 3.3V voltage by 12V voltage transitions.
Described wire is copper bar.Copper bar is a kind of conducting heavy current product, is applicable to the electro-engineerings such as high and low voltage electrical equipment, switch contact, controller switching equipment, bus duct, has resistivity low, the feature that current loading is high.
Described main power board is large plate, and described standby electricity source plate is platelet.Such design can save the cost of sheet material.
The beneficial effects of the utility model are: in technical solutions of the utility model, and standby electricity source plate only retains the power supply input of 12v and 12v_standby, no longer includes relevant power conversion chip, saves the cost of related chip and sheet material.
Above standby electricity source plate is positioned at, can be one piece of little board, the 12V conduction realizing power module exports; Below main power board is positioned at, be one piece of large board, be integrated with above: 12V turns 5V, 12V and turns 3.3V, 12V_standby turns 5V_standby;
Size board is interconnected at together by copper sheet, form an entirety, realize the interconnected of two block power supply plate 12V, can ensure during use: each power module be connected with platelet when large plate, when having a power module to break down, still ensure to server master board normal power supply 12V, 5V, 3.3V, 5V_standby; Thus realize redundant power supply, improve power supply reliability.Meanwhile, large platelet is combined together, and forms an entirety, also to a certain degree reduces design cost.
The utility model discloses a kind of stand-by power supply scheme in generic server, pcb board material cost and device cost can be saved to greatest extent, reduce Redundancy Design.
