Abstract
The invention provides a design method for sharing an input capacitance. According to difference of power sequence, power sources can be divided into a standby power source (STBYPower) and a system power source (CorePower) in a server direct current (DC) power source distribution system. The STBYPower is relatively small in current requirement, and only satisfies the most basic electricity quantity requirement in a standby state of a server. The CorePower is used for satisfying requirements for using electricity quantity of the server in work in any working states. When the server is in use, after the CorePower is electrified, the STBYPower is always switched to the CorePower, the STBYPower closes output, or output current of the STBYPower is basically zero, and therefore a STBYPower module is wasted. Considering that the STBYPower and the CorePower are incapable of simultaneously working, and for reduction of cost, the method for sharing the input capacitance can be selected for use, not only is usage amount of components is reduced, but also the cost is reduced.
Description
Technical field
This present invention relates to server DC power-supply system for electrical domain, is specifically related to a kind of method for designing of shared input capacitance.
Background technology
The fast development of internet makes information resources present explosive growth, and people are take network as media, and the demand of information is also constantly being increased.Various large-scale data center modules also arise at the historic moment.The quantity of the individuality-server of composition data machine room, storage rack is also in continuous increase.Along with the maturation of technology, the extensive use of server also makes server more and more pay attention to the reduction of cost as PC, how completes the design of power supply under more low-cost, has just become more and more urgent task.And input capacitance is as an important component part in cost, and the use amount that reduces input capacitance is one of direction that reduces costs.Thus, this paper has proposed a kind of method for designing that shares to reduce its use amount by input capacitance.
Summary of the invention
Technical assignment of the present invention is to solve the deficiencies in the prior art, and a kind of method for designing of shared input capacitance is provided.
Technical scheme of the present invention realizes in the following manner, with the electric capacity of the input power input capacitance as standby voltage when the holding state, when running status as the input capacitance of system voltage, thereby reduced the use amount of input capacitance, reduced cost, the standby input power that has guaranteed input end is consistent with the system input power, if voltage is inconsistent, will adds a change-over switch between standby input power and system's input power and realize unanimously.
Beneficial effect of the present invention: using this invention, is the standby input power that will guarantee input end consistent with the system input power, and this also meets the product requirement of the present market mainstream.And we just can save a large amount of input capacitances in the Power Management Design process, and do not affect the Performance and quality of our design, have reduced the cost of product integral body, have improved the competitive power of product.
Description of drawings
Fig. 1 is traditional standby power and system power supply structural representation;
Fig. 2 is standby power and the system power supply structural representation that shares input capacitance.
Embodiment
Be described in further detail below in conjunction with the method for designing of accompanying drawing to a kind of shared input capacitance of the present invention.
Accompanying drawing 1 is standby power and the system power supply in traditional server DC power supply; Accompanying drawing 2 shares the standby power of input capacitance and the structural representation of system power supply for employing.
Difference due to electrifying timing sequence, power supply can be divided into standby power (STBY Power) and system power supply (Core Power), the electric current demand less of standby power, only satisfy electric weight demand the most basic under the server holding state, system power supply is to satisfy the be in operation demand that makes power consumption under any duty of server.In use, after system power supply was got up, standby power all can switch to system power supply, and standby power has closed output or output current is zero substantially.So just wasted the standby power module, consider standby power and system power supply not can with the time turn round, in order to reduce costs, a kind of method that we can select input capacitance to share realizes as description of drawings
As shown in Figure 1, in standby power and system power supply in traditional server DC power supply, standby voltage and system voltage are independent separately, finally realize switching with switch at output terminal, use under holding state and treat that electromechanics is former, under normal operating condition, use system power supply.Of course not all system power supplies have corresponding standby power, but necessarily comprise the standby voltage of whole same pressures in the output voltage of system power supply, and the present invention is also for this part circuit.
As shown in Figure 2, the power supply architecture of shared input capacitance of the present invention, the electric capacity of input power is in the input capacitance of holding state as standby voltage, in the input capacitance of running status as system voltage, thereby reduce the use amount of input capacitance, reduced cost, the standby input power that has guaranteed input end is consistent with the system input power, this also meets the product requirement of the present market mainstream, if voltage is inconsistent, will adds a change-over switch and realize between input power.
Be the public office technology of those skilled in the art except the disclosed technical characterictic of instructions of the present invention.
