Description

Conversion Architecture for Redundant Power Systems

technical field

The utility model relates to a conversion framework of a redundant power system, in particular to a framework for integrating a plurality of power supplies and integrating outputs of a redundant power system.

Background technique

The known redundant power system is composed of multiple power supplies. The power supplies in this type of redundant power system adopt the design of sharing mechanism. In other words, multiple power supplies share one casing and control. The power integration backplane used in practice can usually be called N+M architecture. Generally speaking, "N" refers to the number of power supplies that should be combined for the total power load value required by the industrial computer." M" refers to the number of power supplies that can be damaged. Take the 2+1 structure as an example, which is composed of three power supplies. The following 1 means that in the case of one power supply being damaged, the other The power supply can still supply power normally. Of course, according to different needs, there are also special designs for N+2 architecture.

However, the existing redundant power system can refer to the "Structure of Redundant Power Supply" in Taiwan Patent Announcement No. 562163. The content disclosed in the previous case can be seen that more than one chute space 14 is defined in the box body 10. To locate more than one power supply 30, and the multiple power supplies 30 are connected to multiple connectors 12 on the circuit board 11, so that the output power of multiple power supplies 30 can be integrated on the circuit board 11 And form a backup power supply.

The circuit board 11 described in the previous case is actually the well-known "backplane" in redundant power supplies, and the main function of the existing backplane is to integrate the power of multiple power supplies, and the existing backplane is more It needs to have the function of converting power to provide more than one output power of different power levels. However, as the size and specification of the redundant power system have begun to develop towards a thinner and shorter design style, in addition to the individual power supplies, the size needs to be changed In addition to the design, the backplane also faces the following problems in order to reduce the size.

The first problem is the difficulty of reducing the size of the circuit board. As mentioned above, the backplane basically includes the two functions of integrating power and converting power, and because the power and current integrated on the backplane are not low, Therefore, it is more necessary to provide sufficient insulation strength to meet the safety requirements. Reducing the size will cause difficulties in providing insulation strength, and the withstand voltage and insulation specifications of circuit components need to be improved. Overall, it will cause design difficulties and high costs.

The second problem is the difficulty of heat dissipation. To integrate and convert the same current and power, the smaller backplane is of course at a disadvantage in heat dissipation, and the large size of high-current electronic components results in relatively narrow heat dissipation space for air circulation. The reduction in board size increases the power density per unit area, reduces the area in contact with air, and makes it difficult to install heat dissipation components. Therefore, the smaller backplane will encounter difficulty in heat dissipation, which will increase the damage rate.

The third problem is that the power collected by each power supply needs to be converted into 12V, 5V or 3.3V or other voltage levels according to the load demand, and the existing backplane has been set in the design of the conversion circuit. Therefore, it is difficult to change the power and voltage according to different load demands. This problem also limits the expansion capability of the backup power system, even if the backup power system allows the expansion capacity of the front-end power supply , but the rear-end backplane still only provides a fixed number of output lines and voltages, and its performance expansion space is limited.

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

Utility model content

The second circuit board pre-defines at least one plug-in area to connect the conversion module. The conversion module obtains power from the second circuit board and modulates to form At least one output power, so this case can form an independent module through the function of converting power in the redundant power system, so that the manufacturer can replace the conversion modules of different output voltages in the pre-defined plug-in area according to the needs of customers In addition, since the conversion module is an independent small circuit, the second circuit board can have sufficient area to provide heat dissipation and insulation, and also have space to reduce the area.
