Description
Technical field
The utility model relates to solar power distributor, is specifically related to a kind of solar power and distributes collector-shoe gear.
Background technology
In solar power system, according to the bearing power that user uses, all need many group solar panels to provide energy to user load under normal circumstances simultaneously.Solar panel can not directly in parallelly be powered to user load, just can be supplied to user use, because the direct voltage output of solar panel, output current are unstable by circuit or specific device after must being confluxed.Prior art generally realizes in the following manner:
Mode one: the output often organizing solar panel all connects a controller for solar, namely connects a DC-DC converter, exports to user load after the output-parallel of every platform controller for solar.Its defect is: cost is high.
Mode two: the output often organizing solar panel all to be powered to user load by being connected in parallel after a check diode.Its defect is: power output is uncontrollable, exists use hidden danger in the application scenario needing power output controlled (as directly to batteries charging).
Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of with low cost, solar panel collector-shoe gear that power output is controlled.
The purpose of this utility model adopts following technical scheme to realize:
A kind of solar power distributes collector-shoe gear, and comprise controller, multiple solar panel, multiple gating switch and multiple diode, the quantity of described solar panel, gating switch and diode is all equal; One end of gating switch described in each connects one to one in the power output end of each solar panel, and the other end of each gating switch connects one to one the anode of each diode, and the negative electrode of each diode confluxes connected; Described controller has the gating control end equal with gating switch quantity and multiple current sample end, and each gating control end is each gating switch of control connection respectively, and each current sample end is connected with the other end of each gating switch respectively.
On the basis of the above, the utility model also can do following improvement:
Described controller also has a voltage sample end, and this voltage sample end is connected with the negative electrode confluence of each described diode.
Described Strobe Controller is also connected with the display module of communication module and the operating state for the power output parameter He each gating switch that show solar module.
Described communication module is 485 communication modules.
Described controller is MCU controller.
Compared to existing technology, the beneficial effects of the utility model are:
Controller of the present utility model by current sample end detect each solar panel conflux after the output current of total output voltage and every road solar panel, calculate power output.When exporting gross power and also not reaching presetting power-limiting, controller increases the switching quantity of solar panel by each gating switch, make to export gross power and approach presetting power-limiting, finally when exporting gross power and substantially equaling presetting power-limiting, no longer change the input quantity of solar panel, thus the power realized after multiple solar panel output backflow is controlled, and this implementation is with low cost, without the need to all connecting a DC-DC converter costly after each solar panel.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the connection diagram that the utility model solar power distributes collector-shoe gear.
Embodiment
A kind of solar power as shown in Figure 1 distributes collector-shoe gear, comprise controller, multiple solar panel, multiple gating switch and multiple diode, the quantity of solar panel, gating switch and diode is all equal, is that 1 ~ N (N is natural number) is individual.One end of each gating switch connects one to one in the power output end of each solar panel, and the other end of each gating switch connects one to one the anode of each diode, and the negative electrode of each diode confluxes connected; Controller has the gating control end equal with gating switch quantity and multiple current sample end, and each gating control end is each gating switch of control connection respectively, and each current sample end is connected with the other end of each gating switch respectively.
The controller of this example also has a voltage sample end, and this voltage sample end is connected with the negative electrode confluence of each described diode.Then controller can detect solar panel conflux after the output current of total output voltage and every road solar panel, calculate power output.If there is no voltage sample end, then the electric current of the rated output voltage of solar panel and detection acquisition also can be utilized to obtain power output.
When exporting gross power and also not reaching power-limiting, controller increases the switching quantity of solar panel by gating switch, make to export gross power and approach presetting power-limiting, finally when exporting gross power and substantially equaling power-limiting, no longer change the input quantity of solar panel.When exporting gross power and exceeding presetting power-limiting, controller reduces the switching quantity of solar panel by gating switch, make to export gross power and approach power-limiting, finally when exporting gross power and substantially equaling power-limiting, no longer change the input quantity of solar panel.The power exported through the negative electrode of each diode is then controlled.
Strobe Controller is also connected with the display module of communication module and the operating state for the power output parameter He each gating switch that show solar module.Whole running parameters of whole collector-shoe gear show by display module, inquire about for user.Communication part can with other peripheral device communication.Wherein, each diode is used for preventing electric current converse.Communication module is 485 communication modules.Controller is MCU controller.Controller is only for obtaining current sample end, after the power that calculates of data that voltage sample end obtains, compare with presetting power-limiting, then exportable control signal controls the folding of gating switch.Therefore, this controller also can adopt existing regular logical comparison circuit, enters in MCU controller without the need to software program burning.
Above-mentioned execution mode is only preferred implementation of the present utility model; can not limit the scope of the utility model protection with this, change and the replacement of any unsubstantiality that those skilled in the art does on basis of the present utility model all belong to the utility model scope required for protection.
