Each solar cell string group is in series with an optimization chip, when blocking, solar cell string group
Output current is reduced, and optimization chip is detected after the change of electric current, and solar cell string group is lifted by the algorithm for being depressured up-flow
Output current, reduction output voltage, although reduce power, but the solar cell string group can be avoided to be formed because electric current is low
For the load of whole component, enter to prevent the power that the solar cell string group blocked consumes whole component.Therefore,
By the algorithm for being depressured up-flow, it is ensured that the solar cell string group for occurring blocking still carries out power output, compared to existing
Directly the solar cell string group for occurring blocking is bypassed with bypass diode in technology, when blocking, whole group
The power output of part is lifted.And when shielded area increase, when solar cell string group produces reverse biased, optimize chip
Detect after the change, enable bypass functionality, corresponding solar cell string group is subjected to bypass shielding, it can be avoided to turn into group
The load reduction component power output of part, can also protect the solar cell string group, it is to avoid to the solar cell string group
Hardware causes to damage.
Further, optimization chip includes negative pole connectivity port, the first anode connection terminal mouthful and the second anode connection terminal mouthful,
Optimization chip is connected into the connection circuit of solar battery sheet group by negative pole connectivity port and the first anode connection terminal mouthful, multiple
Optimization chip is attached by the first anode connection terminal mouthful and the second anode connection terminal mouthful each other, the connection side used
Formula can be in parallel or series.
Further, optimization chip is additionally provided with data communication module, between achievable each independent optimization chip
Communication function.Realize after communication function, can further optimize to the defeated of each solar cell string group between each optimization chip
Go out the control of power, when integrally blocking, further can maintain the power output of whole component one higher
Level, without directly will by serious shielding solar cell string group carry out bypass shielding.
Further, solar cell string group is arranged in pairs and at least provided with two pairs, each pair solar cell string group
In solar cell string group be arranged symmetrically, in battery component positioned at the same side solar cell string group connected after,
The solar cell string group of both sides is carried out again in parallel.
Compared with prior art, present invention utilization, which optimizes chip, can lift output work of the whole component when being blocked
Rate, and optimization chip volume is small, connects simple in construction with installation, installation cost is low.
Brief description of the drawings
The present invention is further described below in conjunction with the accompanying drawings.
Fig. 1 is theory structure schematic diagram of the invention；
Fig. 2 is positive structure schematic of the invention；
In figure：1st, solar cell string；2nd, chip is optimized.
Embodiment
Below in conjunction with the accompanying drawings and embodiment the present invention will be described in detail：
As shown in Figures 1 and 2, this new half battery component includes 12 solar cell strings 1, each solar-electricity altogether
Pond string 1 is in series by multiple half batteries, and two adjacent solar cell strings 1 form solar cell string by series connection
Group, the terminal tandem of each solar cell string group has an optimization chip 2.Solar cell string component is both sides arrangement, often
The solar cell string group of side is first connected, and then the solar cell string group of both sides is carried out in parallel, progress power output again.
Optimize the voltage and current state of the detectable correspondence solar cell string group of chip 2, optimization chip 2 is also stored with drop
The algorithm of up-flow is pressed, optimization chip 2 also has bypass functionality.Optimizing chip 2 includes negative pole connectivity port, the first anode connection terminal
Mouth and the second anode connection terminal mouthful, optimization chip 2 are connected into solar energy by negative pole connectivity port and the first anode connection terminal mouthful
The connection circuit of cell piece group, multiple optimization chips 2 pass through the first anode connection terminal mouthful and the second anode connection terminal each other
Mouthful it is attached, after first the optimization chip 2 of the same side is connected, then by 2 parallel connections of optimization core of not homonymy.Optimize chip 2
With PORT COM, it can be communicated between each optimization chip 2 by PORT COM, obtain each solar cell string group
Voltage and current information.Each PORT COM is communicated by data connecting line.
When all solar cell string groups in whole component are unobstructed, component optimizes core with maximum power output
Piece 2 detects and records the voltage and electric current of now each corresponding solar cell string group.When solar cell string group hides
During gear, the output current of solar cell string group is influenceed and reduced by illumination reduction, and optimization chip 2 detects the change of electric current
Afterwards, the output current of solar cell string group, reduction output voltage are lifted by the algorithm of built-in decompression up-flow, makes to be blocked
Solar cell string group continue to output power.And for the half battery component of common use bypass diode, blocked
Solar cell string group can by bypass diode, lose power output output.Therefore, compared to prior art, this new half
Piece battery component realizes the lifting of power output.
And when shielded area increase, when solar cell string group produces reverse biased, beyond the adjustable range of optimization chip 2
Or the solar cell string group trouble free service scope when, optimization chip 2 enables bypass functionality, disconnects the negative pole of chip internal first
Connectivity port and the electrical connection of the first anode connection terminal mouthful, are connected between the first anode connection terminal mouthful and the second anode connection terminal mouthful
Electrical connection so that by corresponding solar cell string group carry out bypass shielding, can avoid its turn into component load reduction group
Part power output, can also protect the solar cell string group, it is to avoid the hardware of the solar cell string group is caused to damage.
When there is multiple solar cell string groups to block, multiple optimization chips 2 detect each self-corresponding solar energy
After the electric current of battery strings group, voltage change, detected electric current, magnitude of voltage are transmitted mutually, each optimization chip 2
Real-time current, the magnitude of voltage of each solar cell string group in whole component can be obtained, thus is carrying out decompression up-flow regulation
During the power output of correspondence solar cell string group, it can be opened according to the power output of whole component, reduction output threshold value, reduction
The triggering power level of dynamic bypass functionality, makes whole component realize power when there is multiple solar cell string groups to block
The maximization of output.
