Abstract
The utility model proposes it is a kind of can be to the rectification unit of inversion unit centrally connected power supply, the rectification unit being connected including AC input cell, with AC input cell, also include the buffer cell being connected with the positive pole of rectification unit, the buffer cell includes switch I and with switching I buffer resistance in parallel, and switch II is serially connected with the branch road where buffer resistance.The utility model make it that the direct current output in each electrical equipment loop is controllable, and buffering can be had by leading to direct current again after disconnection direct current every time, small to power network impact, small to direct-flow electricity utilization apparatus impact, reduce the spoilage of equipment.
Description
Technical field
The utility model is related to it is a kind of can be to the rectification unit of inversion unit centrally connected power supply.
Background technology
Existing rectification unit is uncontrollable rectification, directly upper electricity, and dash current is larger.Output direct current can not individually break
Open, DC dump needs to disconnect input, influences the other equipment of common input.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, there is provided one kind can be concentrated to inversion unit
The rectification unit of power supply, this rectification unit can buffer electric current during energization, reduce the impact to power network and electrical equipment.
To achieve the above object, the utility model uses following technical proposals：It is a kind of can be to inversion unit centrally connected power supply
Rectification unit, including AC input cell, the rectification unit that is connected with AC input cell, in addition to the positive pole with rectification unit
The buffer cell of connection, the buffer cell include switch I and with switching I buffer resistance in parallel, the branch where buffer resistance
Switch II is serially connected with road.
In use, switch I is off-state when being powered, first ON switch II, due to the limit of buffer resistance in circuit loop
Stream is acted on so that dash current is greatly reduced, and cushion pad is hindered short circuit, power grid operation by ON switch I after belt current is stable；
When needing to disconnect electrical equipment, switch I and switch II are individually disconnected, it is not necessary to disconnect AC input cell, avoid shadow
Ring other common input equipments.
The beneficial effects of the utility model are：The utility model make it that the direct current output in each electrical equipment loop is controllable,
Buffering can be had by leading to direct current after disconnection direct current again every time, and small to power network impact, small to direct-flow electricity utilization apparatus impact, reduction is set
Standby spoilage.

Fig. 1 is structural representation of the present utility model.
Shown in figure：1st, AC input cell, 2, rectification unit, 3, buffer cell, 4, switch I, 5, switch II, 6, buffering
Resistance.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
As shown in Figure 1 a kind of can be to the rectification unit of inversion unit centrally connected power supply, including AC input cell 1 and friendship
The rectification unit 2 that input block 1 connects, in addition to the buffer cell 3 being connected with the positive pole of rectification unit 2 are flowed, the buffering is single
Member 3 includes switch I 4 and with switching I 4 buffer resistances 6 in parallel, and switch II 5 is serially connected with the branch road where buffer resistance 6.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc., the utility model should be included in
Protection domain within.
