Abstract
The utility model relates to a DC power supply, in particular to a DC power supply in which an automatic current-sharing module is arranged. The DC power supply comprises a DC module and a DC output end, wherein a diode current-sharing module is connected between the DC module and the DC output end in series. With the adoption of the technical, the automatic current-sharing DC power supply has simple structure, is convenient to use and can share the current automatically.
Description
Technical field
The utility model relates to a kind of DC power supply, specifically is a kind of DC power supply that is built-in with the automatic current equalizing module.
Background technology
DC power supply is as a kind of stabilized voltage power supply product; be widely used in technical fields such as instrument, control, protection, signal circuit and batteries charging; along with the user constantly increases the demand of high-power DC power supply, require very common to a few kilo-ampere output currents.When power supply needed bigger electric current to export, the power output size of the power model of separate unit power supply was limited, and it is difficult to satisfy ever-increasing power instructions for use.Therefore can only be by many power supply parallel operation being realized big electric current output.Yet in the process of many power supply parallel operation dilatations, brought new problem: because most of DC power supplier product itself does not possess the ability that redundant current-sharing is used, therefore want in parallel the use, often need to carry out current-sharing, promptly connect a diode current-sharing module again in the DC power supply periphery by external current-sharing module.Doing the immediate problem that faces like this is: 1, and this external current-sharing module need go separately to buy, and wastes time and energy, and influence is used; 2, after parallel operation is used, in rack, look for a suitable position also must for external current-sharing module, because common rack setting is all compact, so usually install very inconvenient.
The utility model content
The technical problems to be solved in the utility model is: a kind of simple structure is provided, and easy to use, DC power supply that can automatic current equalizing.
In order to solve the problems of the technologies described above, the utility model provides a kind of novel automatic current equalizing DC power supply, includes direct current module and dc output end, is serially connected with a diode current-sharing module between described direct current module and the dc output end.
Adopt the novel automatic current equalizing DC power supply of technique scheme to have following advantage: 1, owing to be serially connected with a diode current-sharing module between direct current module and the dc output end, when so the user thinks redundant the use, just do not need to buy once more redundant module, it is just passable only to need that two DC power supply of the technical program are directly carried out parallel connection, the user uses time saving and energy saving, and is very convenient; 2, because the diode current-sharing module has realized being installed to DC power supply inside, so can avoid external current-sharing module to be not easy to be installed to the problem of rack inside.
Further limit, described diode current-sharing module is an isolating diode.
Description of drawings
Fig. 1 is the schematic block diagram of the utility model embodiment.
Embodiment
Below in conjunction with drawings and Examples technical solutions of the utility model are further specified:
As shown in Figure 1, the utility model provides a kind of novel automatic current equalizing DC power supply, and its structure is basically with existing conventional DC power supply, and main distinctive points is to be serially connected with diode current-sharing module 3 between direct current module 1 and the dc output end 2; When the user needs redundant the use, only the input 4 and the dc output end 2 of a plurality of automatic current equalizing DC power supply need be in parallel, because power supply inside is provided with diode current-sharing module 3, can realize the automatic current equalizing of DC power supply.
For the conventional DC power supply, owing to itself do not have the automatic current equalizing device, when the user needs redundancy, need the extra external diode current-sharing module of apolegamy, use inconvenience, and look for a position also to compare difficulty in the DC power supply rack, for external diode current-sharing module.And the automatic current equalizing DC power supply that the utility model provides owing to be built-in with diode current-sharing module 3, can avoid occurring the problems referred to above.
Above-mentioned diode current-sharing module 3 is an isolating diode.
Above-described only is preferred implementation of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection range of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
Claims (2)
1. a novel automatic current equalizing DC power supply includes direct current module and dc output end, it is characterized in that: be serially connected with a diode current-sharing module between described direct current module and the dc output end.
