Abstract
The utility model discloses a large-power power supply. The power supply comprises a controller, a power module and a rectifier filter, wherein a plurality of power change modules are arranged in the power module, the controller is connected with the power module and the rectifier filter, the rectifier filter is also connected with the power module. The large-power output is realized and simultaneously the production cost is effectively reduced. The large-power power supply has other obvious advantages of low mounting difficulty, improved heat radiation performance, reasonable structure, convenient use, wide application range, and low production cost.
Description
Technical field
The utility model relates to power supply, relates in particular to a kind of large power supply.
Background technology
Along with expanding economy, increasing occasion needs large power supply.For example airport, harbour, industrial and mining enterprises, square, warehouse or the like.And to large power supply require increasingly highly, power requirement also progressively increases.But all there is limitation in existing large power supply at aspects such as the capacity of single tube, price, heat radiation, installations, therefore, can not satisfy the requirement in market.
Therefore, need provide a kind of large power supply to address the above problem.
Summary of the invention
In order to address this problem; The utility model discloses a kind of large power supply; Said large power supply comprises controller, power model and rectifier filter; Be provided with a plurality of variable power modules in the said power model, said controller is connected with said rectifier filter with said power model, and said rectifier filter also is connected with said power model.
Further, said power model also comprises positive terminal and negative terminal.
As a scheme, said a plurality of variable power modules are through being connected in series.
As another scheme, said a plurality of variable power modules are through being connected in parallel.
The large power supply of the utility model can when realizing high-power output, effectively reduce production costs, and installation difficulty is low, and heat dispersion improves, and has significant advantages such as rational in infrastructure, easy to use, applied widely, that production cost is low.
In the utility model content part, introduced the notion of a series of reduced forms, this will further explain in the embodiment part.The utility model content part does not also mean that key feature and the essential features that will attempt to limit technical scheme required for protection, does not more mean that the protection range of attempting to confirm technical scheme required for protection.
Below in conjunction with accompanying drawing, specify the advantage and the characteristic of the utility model.
Description of drawings
Fig. 1 is the structural representation according to the large power supply of an embodiment of the utility model.
Embodiment
In the description hereinafter, provided a large amount of concrete details and the utility model has been understood more completely so that provide.Yet, it will be apparent to one skilled in the art that the utility model can need not one or more these details and be able to enforcement.In other example,, describe for technical characterictics more well known in the art for fear of obscuring with the utility model.
In order thoroughly to understand the utility model, detailed structure will be proposed in following description.Obviously, the execution of the utility model is not limited to the specific details that those skilled in the art has the knack of.The preferred embodiment of the utility model is described in detail as follows, yet except these were described in detail, the utility model can also have other execution modes.
Below with reference to accompanying drawing the embodiment of the utility model is made detailed description.
With reference to figure 1, be structural representation according to the large power supply of an embodiment of the utility model.This large power supply comprises controller 1, power model 2, and rectifier filter 3 is provided with a plurality of variable power modules 21 in the power model 2.Controller 1 is connected with rectifier filter 3 with power model 2, and rectifier filter 3 also is connected with power model 2.Power model 2 also comprises positive terminal 22 and negative terminal 23.
Wherein above-mentioned a plurality of variable power module 21 can be connected in series or be connected in parallel.When being connected in series, can realize that output current is little, voltage is high; When being connected in parallel, can realize that output voltage is low, output current is big.Through these variable power modules, can under equal conditions realize high-power.
The large power supply of the utility model can when realizing high-power output, effectively reduce production costs, and installation difficulty is low, and heat dispersion improves, and has significant advantages such as rational in infrastructure, easy to use, applied widely, that production cost is low.
The utility model is illustrated through the foregoing description, but should be understood that, the foregoing description just is used for for example and illustrative purposes, but not is intended to the utility model is limited in the described scope of embodiments.It will be understood by those skilled in the art that in addition; The utility model is not limited to the foregoing description; Instruction according to the utility model can also be made more kinds of variants and modifications, and these variants and modifications all drop in the utility model scope required for protection.The protection range of the utility model is defined by appended claims book and equivalent scope thereof.
