Description
Technical field
The present invention relates to power system technologies field, specifically a kind of on line type UPS power-supply system based on super capacitor.
Background technology
On line type UPS power supply is frequently necessary to for first order load, on line type UPS power supply, under normal circumstances, nothing
By whether there is or not alternating currents, it is avoided all by utility grid voltage wave so always by the inverter of ups power to load supplying
The influence that dynamic and interference fringe comes may be implemented frequency stabilization, voltage stabilizing power supply to load, and be supplied being transformed into accumulator by mains-supplied
When electric, conversion time zero.
In existing on line type UPS power supply, accumulator group is connected to rectifier output end and inverter input terminal, in power supply
In the state of interruption, accumulator group can provide power supply to inverter at once, and the output of system is made to keep continuous power supply, this existing
Some on line type UPSs are uninterrupted in order to power supply, accumulator needs the moment to be online, even if not coming into operation
In the case of, carry out charge and discharge that accumulator also can be repeatedly.Therefore, the service life is relatively short, makes the operating cost of online UPS
It greatly improves, practicability is not strong.
Invention content
The on line type UPS power-supply system based on super capacitor that the purpose of the present invention is to provide a kind of, to solve the above-mentioned back of the body
The problem of being proposed in scape technology.
To achieve the above object, the present invention provides the following technical solutions：
A kind of on line type UPS power-supply system based on super capacitor, including rectifier, accumulator group and inverter, it is described
The input terminal of inverter and the output end of rectifier are electrically connected with ultracapacitor group.
As a further solution of the present invention：It is connected with charge control between the output end and accumulator group of the rectifier
Device.
As a further solution of the present invention：It is connected with input control between the input terminal and accumulator group of the inverter
Device.
As a further solution of the present invention：It is connected with power supply between the input terminal and accumulator group of the rectifier.
As further scheme of the invention：It is connected between the output end and ultracapacitor group of the inverter negative
It carries.
Compared with prior art, the beneficial effects of the invention are as follows：
A kind of on line type UPS power-supply system based on super capacitor, it is reasonable for structure, it is novel in design, use super capacitor
Energy-storage travelling wave tube of the device as the online part of UPS, using accumulator as the backup power supply of UPS, such accumulator can be located
In backup status, to extend its working life, the maintenance cost of equipment is reduced, it is highly practical.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of the on line type UPS power-supply system based on super capacitor.
Fig. 2 is the structural schematic diagram of existing on line type UPS power-supply system in background technology.
Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
It please refers to Fig.1 and Fig. 2, in the embodiment of the present invention, a kind of on line type UPS power-supply system based on super capacitor, packet
Rectifier, accumulator group and inverter are included, the input terminal of the inverter and the output end of rectifier are electrically connected with super
Capacitor group is connected with charge controller, the input terminal of the inverter between the output end and accumulator group of the rectifier
It is connected with input control device between accumulator group, is connected with power supply between the input terminal and accumulator group of the rectifier, institute
It states and is connected with load between the output end of inverter and ultracapacitor group.
The present invention operation principle be：Under power supply normal condition, the output end of rectifier is being supplied to inverter power supply
It also charging simultaneously to ultracapacitor group, rectifier also separates portion of energy and charges to battery pack, in the state of power interruptions,
Ultracapacitor group can export electric energy to inverter at once, so that the output of system is not interrupted, system is in detecting power supply
It has no progeny, starting storage battery group puts into operation, although there is the delay of short time, due to the presence of ultracapacitor group, makes
The output of whole system is unaffected, since ultracapacitor group only bears the very short time, so its capacity also need not be very big,
Cost is not also high, due to accumulator group it is fully charged after be in off-line state, as long as power supply does not interrupt, accumulator group not work
Make, therefore the service life of accumulator group can greatly prolong, and reduce operation, maintenance cost, it is highly practical.
It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, Er Qie
In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, the present embodiments are to be considered as illustrative and not restrictive, and the scope of the present invention is by appended power
Profit requires rather than above description limits, it is intended that all by what is fallen within the meaning and scope of the equivalent requirements of the claims
Variation is included within the present invention.Any reference signs in the claims should not be construed as limiting the involved claims.
In addition, it should be understood that although this specification is described in terms of embodiments, but not each embodiment is only wrapped
Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should
It considers the specification as a whole, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
