Description
Technical field
It the utility model is related to power circuit technical field, and in particular to a kind of distributed DC power.
Background technology
Dc source is typically to select direct current cabinet, and the direct current cabinet of now is typically to be made up of charging module and battery.
Charging module is for supplying stable charging current to battery pack, when electricity is disconnected, gives control female power supply, it is ensured that direct current stable system
Output；Nowadays, domestic high frequency switch power template is to use international advanced technology, and according to the demand next life of the country
Production.Power template is very convenient with getting up, and electric current can be apparent on panel above, in the running can also very just
Output situation of inspection electric current of profit etc., the conditioning system that can also pass through plate back are nursed one's health voltage and current.It is single
Module both can finish various basic training of unit operation use, again can with combine operation after multiple wired in parallel.Module group passes through one
Analog interface is connected with microcomputer, whole system is completed four distant functions.Module can also pass through switching value and switch equal, floating charging
Pressure.Module itself also has perfect protection function, it is ensured that the peace of system under module or module group independent operation and micro computer monitoring
Entirely.Batteries are in series by multiple batteries, are 18 section 12V batteries (or 108 section monomers on 220V voltage class
Battery) series connection, 110V voltage class is 9 section 12V batteries (or 54 section cells) series connection.Traditional direct current cabinet and distribution
Dc source compares, and has several inferior positions：First, method of supplying power to.Traditional direct current cabinet is not the method for centrally connected power supply, and divides
Cloth dc source is then the method from distributed power supply, the power-supply device in other loops when certain primary Ioops finds failure simultaneously
It is unaffected, avoiding problems a point failure whole station is presented not have the query of DC operation electric current.Which greatly increases
Overall reliability.Second, battery failure.The usual demand 18 of traditional direct current cabinet saves the series connection of 12V batteries, and distributed DC is electric
Flow a demand 2 and save the series connection of 12V batteries, battery is that the probability contrast of failure is small, and a battery failure can only influence a part
Switch, a query of the point failure whole station without DC operation can be effectively prevented from.3rd, battery protection.Because traditional is straight
Battery contrast needed for stream screen is more, so also relative contrast is more for the required battery protection done when failure is presented.4th, device is adjusted
Examination.Traditional direct current cabinet volume vs are big, and demand takes up an area device, and contrast is bothersome.
Utility model content
The utility model overcomes the deficiencies in the prior art, there is provided a kind of distributed DC power.
To achieve the above object, the utility model uses following technical scheme：
A kind of distributed DC power, it includes electromagnetic interface filter, rectifier, Pfc converter module, DC/DC converter moulds
Block and load point conversion module, the electromagnetic interface filter, rectifier, Pfc converter module, DC/DC conversion modules and load
Point conversion module is sequentially connected electrically, and the Pfc converter module is made up of several Pfc converters parallel with one another, described
DC/DC conversion modules are made up of several DC/DC converters parallel with one another, and the load point conversion module is by several
Load point converter composition parallel with one another.
Further technical scheme is that the DC/DC converters use 400/48V DC/DC converters.
Compared with prior art, the beneficial effects of the utility model are：
1st, cloth dc source is directly installed on intelligent switchboard by the utility model according to Embedded design philosophy
In instrument box, floor space can be saved.Because power supply is in switch cubicle, the usage amount of cable can be reduced, saves primary equipment investment
And cable construction workload.
2nd, the utility model is applied widely, can be exported according to the demand of client offer direct current 220V, 110V, 48V, 24V,
Exchange input range is 85~265V, is flexibly applied to mains-supplied.
Brief description of the drawings
Fig. 1 is a kind of structured flowchart of the distributed DC power of embodiment of the utility model.
As shown in figure 1, wherein corresponding reference is entitled：
1 electromagnetic interface filter, 2 rectifiers, 3 Pfc converters, 4 DC/DC converters, 5 load point converters.
Embodiment
The utility model is further elaborated below in conjunction with the accompanying drawings.
Distributed DC power as shown in Figure 1, it includes electromagnetic interface filter 1, rectifier 2, Pfc converter module, DC/
DC conversion modules and load point conversion module, the electromagnetic interface filter 1, rectifier 2, Pfc converter module, DC/DC conversions
Device module and load point conversion module are sequentially connected electrically, and the Pfc converter module is changed by several PFC parallel with one another
Device 3 forms, and the DC/DC conversion modules are by several DC/DC converters 4 parallel with one another into a converter is put in the load
Module by several load point converters 5 parallel with one another into.
Preferably, the 400/48V DC/DC converters of DC/DC converters 4, the full name of Pfc converter 3 be with
The AC/DC converters of PFC (PFC).
Operation principle of the present utility model is as follows：
AC-input voltage is obtained after electromagnetic interface filter 1 and the filtering of rectifier 2 and rectification by Pfc converter 3
400V DC voltages, then DC voltage that 400V DC voltages are converted into 48V by DC/DC converters 4 again are connected to bus, then
Through overload point converter by 48V busbar voltage, it is converted into loading required DC voltage, such as 5V, 3V.It can be seen that it is being distributed
In formula powersupply system, the parallel connection of AC/DC and DC/DC conversion modules has all been widely applied.
Essence of the present utility model is described in detail above embodiment, but can not be to of the present utility model
Protection domain is limited, it should be apparent that, under enlightenment of the present utility model, those of ordinary skill in the art can be with
Carry out many improvement and modification, it should be noted that these are improved and modification all falls in claim of the present utility model protection
Within the scope of.
