Abstract
The utility model relates to a power supply, concretely speaking is a redundancy power supply with high cost performance, whose structure comprises a voltage output circuit and a back plate. A voltage switching circuit is positioned on the back plate, and the voltage output circuit is connected with the back plate. Compared with the prior art, the utility model is a redundancy power supply with high cost performance and the utility model is characterized in that: the utility model is of a proper design and simple structure, which can reduce the production cost.
Description
Technical field
The utility model relates to a kind of power supply, and a kind of high performance-price ratio redundant power specifically is provided.
Background technology
Redundant power under the prior art is that module is made independently power supply, and backboard mainly plays the effect of circuit connected sum fault alarm, so redundant power that adopts this mode to realize, its module line design is very complicated, have several modules just have several groups independently 3.3V, 5V ,-circuit such as 12V and 12V, the cost of manufacture height.
Summary of the invention
The utility model is at above deficiency, and a kind of reasonable in design, simple in structure, high performance-price ratio redundant power that can reduce production costs is provided.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of high performance-price ratio redundant power comprises voltage follower circuit and backboard, and described backboard is provided with voltage conversion circuit, and described voltage follower circuit connects described backboard.
Also be provided with protective circuit on the backboard.
Voltage follower circuit is 5VSB output circuit and 12V output circuit.
High performance-price ratio redundant power of the present utility model only designs 5VSB and two groups of basic output circuits of 12V, other as 3.3V ,-12V and 5V then convert from common backplane, adopt the redundant power of this realization, not only improved efficient, and saved 3.3V ,-12V and 5V output circuit, therefore directly reduced cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a kind of structure principle chart of high performance-price ratio redundant power.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.
Provide a most preferred embodiment below:
As shown in Figure 1, a kind of high performance-price ratio redundant power comprises voltage follower circuit and backboard, and described backboard is provided with voltage conversion circuit, and described voltage follower circuit connects described backboard.
Voltage follower circuit comprises fuse, filter circuit, pfc circuit i and the rectifier bridge of serial connection, and rectifier bridge connects 5VSB transformer and 12V transformer in parallel respectively, goes back and be connected to pwm circuit on described 5VSB transformer and the 12V transformer.
Also be provided with protective circuit on the backboard.
Voltage follower circuit is 5VSB output circuit and 12V output circuit.
Above-described embodiment, the utility model embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection range of the present utility model.
