Wherein, the connecting pin of the anode of the second diode D3 and the first capacitance C1 are as first switch formula voltage conversion circuit Output end Out cathode (i.e. the cathode of the output end Out of first voltage conversion equipment), directly be electrically connected the first photovoltaic cell The cathode of U1, while being also electrically connected with the inverting input of the first amplifier O1.
The connecting pin of first inductance L1 and the first capacitance C1 then output end Out as first switch formula voltage conversion circuit Anode, be electrically connected the first amplifier O1 in-phase input end.
The output end of first amplifier O1 is then electrically connected with the input terminal of power-supply controller of electric.
When the output voltage of the first photovoltaic cell U1 changes (such as：The output voltage of first photovoltaic cell U1 reduces) When, at this time the voltage at the first both ends photovoltaic cell U1 be less than the first both ends capacitance C1 voltage (i.e. the first photovoltaic cell U1's is defeated Go out voltage of the voltage less than the output end Out of first switch formula voltage conversion circuit), this allows for diode D1 conductings.Two poles After pipe D1 conductings, the voltage of the output end Out of first switch formula voltage conversion circuit is caused to decline.
Again due to the positive of the first amplifier O1 of anode electrical connection of the output end Out of first switch formula voltage conversion circuit Input terminal, the cathode of the output end Out of first switch formula voltage conversion circuit are electrically connected the inverting input of the first amplifier O1, Therefore, it is changed accordingly by the voltage that the output end of the first amplifier O1 is exported to power-supply controller of electric.Power supply control as a result, The variation for the data that device processed is exported according to the output end of the first amplifier O1 and then the output electricity for monitoring the first photovoltaic cell U1 The variation of pressure.
When the data monitoring that power-supply controller of electric is exported by the first amplifier O1 output ends to the defeated of the first photovoltaic cell U1 Go out after voltage changes, according to the variation adjustment output of the voltage of the first amplifier O1 output ends output to the first N-channel field The duty ratio and/or frequency of the pulse signal of the grid of effect pipe Q1, control the first N-channel field-effect tube conducting dutycycle and/ Or frequency variation, so that the output electric energy of series battery passes through the first mutual inductor T1, the first diode D2, the two or two pole Pipe D3, the first inductance L1 and diode D1 are supplemented to the first photovoltaic cell U1 in time so that the output of the first photovoltaic cell U1 Voltage is kept closer to the state of optimum operating voltage point.
When the output voltage of the first photovoltaic cell U1 does not change, i.e. the moment is maintained at optimum operating voltage dotted state When, then the moment is maintained at fixed voltage value to the voltage at the first both ends capacitance C1 at this time, which is less than and close to The voltage value of the optimum operating voltage of one photovoltaic cell U1, i.e. the output end Out of first switch formula voltage conversion circuit is kept In fixed voltage value, the positive input voltage and reverse inter-input-ing voltage that hence input to the first amplifier O1 surround the fixed voltage Microoscillations, and then equally can slightly be fluctuated by the voltage that the output end of the first amplifier O1 is exported to power-supply controller of electric.As a result, Power-supply controller of electric by adjusting the pulse signal exported to the first N-channel field effect transistor duty ratio and/or frequency, to So that the voltage value at the first both ends capacitance C1 is maintained at the fixed voltage value.
More specifically, when such as the first photovoltaic cell U1 is GaAs photovoltaic cell, due to the reason of GaAs photovoltaic cell Think that operating voltage is 2.75V, when the light of any one section GaAs photovoltaic cell of series battery is on the weak side, the section GaAs The own light of photovoltaic cell can generate electric current 9A, and other GaAs photovoltaic cell light can generate electric current in series battery 11A.In order to meet the equal characteristic of series battery electric current, the voltage of the light section GaAs photovoltaic cell on the weak side can be substantially Degree declines.When the voltage of the light section GaAs photovoltaic cell on the weak side declines, the positive input voltage of the first amplifier O1 It is corresponding to the voltage difference of reverse inter-input-ing voltage to change, and then the voltage of the output end output of the first amplifier O1 can also occur Corresponding variation.To be adjusted from power-supply controller of electric to the first N-channel field according to the variation of the voltage of the first amplifier O1 outputs The duty ratio of the pulse signal of the grid input of effect transistor so that the output electric energy of series battery can be by first mutually Light arsenic on the weak side is replenished in time in sensor T1, the first diode D2, the second diode D3, the first inductance L1 and diode D1 Change in gallium photovoltaic cell so that the voltage of the section GaAs photovoltaic cell maintains near 2.7V, so that the section GaAs The generating efficiency of photovoltaic cell reaches the 98% of its ideal generating efficiency, substantially equal to optimum efficiency, has given full play to the section arsenic Change the photoelectric conversion capacity of gallium photovoltaic cell.
Correspondingly, referring to Figure 12, second voltage conversion equipment corresponding with the second photovoltaic cell U2 includes second switch formula Voltage conversion circuit, the second amplifier O2 and power-supply controller of electric.Wherein, second switch formula voltage conversion circuit includes then the 2nd N Slot field-effect transistor Q2, the second mutual inductor T2, the first diode D5, the second diode D6, the electricity of the second inductance L2 and second Hold C2.
Specifically, the second N-channel field effect transistor Q2, the second mutual inductor T2, the first diode D5, the second diode Connection between connection relation and above-mentioned each device and diode D4 between D6, the second inductance L2 and the second capacitance C2 is closed System is identical as the connection relation of each device in first switch formula voltage conversion circuit, and therefore, details are not described herein again.
In one embodiment, it is connected by 4 photovoltaic cell A, photovoltaic cell B, photovoltaic cell C, photovoltaic cell D and forms series connection Photovoltaic cell group, 4 photovoltaic cells are three section GaAs photovoltaic cells, defer to its IV characteristic curve feature.If certain moment 4 Photovoltaic cell is in optimum Working, and output current is 10A (ampere), output voltage 2.75V.Then there is tandem photovoltaic electric Total output voltage of pond group is 11V, total output current 10A, gross output=11*10=110W.When photovoltaic cell A is by light path When diameter is at least partially obscured, corresponding output current drops to 7A (ampere), because series loop current is equal, at this time according to IV Curve, photovoltaic cell A are difficult to reach the output current of other photovoltaic cells B, photovoltaic cell C, photovoltaic cell D, output electricity Pressure is dropped to close to 0V.And other photovoltaic cells B, photovoltaic cell C, photovoltaic cell D reach recommended current 10A because being difficult to (ampere) then has total output voltage to be approximately equal to 3.1*3=to which output voltage rises to the battery maximum output voltage of 3.1V 9.3V, total output current are equal to 7A (ampere), and gross output=7*9.3=65.1, this has dropped about than ideal output power 40%.If at this moment balancing circuitry is intervened, to photovoltaic cell A output current 3A, its output voltage is made to reach 2.7V, this needs From the total defeated of tandem photovoltaic cells group (the photovoltaic cell A, photovoltaic cell B, the photovoltaic cell C and photovoltaic cell D that are connected in series with) Go out power and obtain energy, and consume about 10% gross output, then needs the power subtracted (to compensate work(by gross output Rate) it is 3*2.7/0.9=9W.Tandem photovoltaic cells group (the photovoltaic cell A that is connected in series with, photovoltaic cell B, photovoltaic cell C and Photovoltaic cell D) total output voltage be 2.75*3+2.7=10.95V, do not reduce compensation total output current be equal to 10A (peace Training), then have and do not reduce the gross output of compensation as 10.95*10=109.5W, reduces compensation power 9W, still there is 100.5W's Gross output, gross output when than perfect condition have dropped about 8.7%.And institute is blocked in this decline, substantially light Caused by, than no balancing circuitry the case where multiple electricity 35.4W.It can be seen that battery output balancing unit is in the uneven situation of light Under remain to keep photovoltaic cell best photoelectric conversion efficiency.
As described above, battery output balancing unit passes through the input terminal of voltage conversion device and the output end of series battery Electrical connection, makes battery output balancing unit using the output of series battery as working power, and voltage conversion device output is less than And the fixed voltage of the optimum operating voltage close to the battery unit in series battery, unidirectional current conduction device compare in real time Compared with the output voltage of the output voltage and corresponding voltage conversion device of the battery unit in series battery.Work as series battery In battery unit output voltage be less than corresponding voltage conversion device output voltage when, unidirectional current conduction device is led Logical, voltage conversion device makes its voltage be kept closer to the voltage shape of optimum operating voltage to the battery unit output current In state.So that the efficiency of each economize on electricity pool unit in series battery is all not in the phenomenon that significantly decline.To have When effect ground solves that battery light is uneven in existing tandem photovoltaic cells group, photovoltaic cell operating voltage understands substantial deviation most Good operating voltage, thus the problem of seriously reducing the photoelectric conversion efficiency of photovoltaic cell.
It is worth noting that any of the above-described kind of battery output balancing unit can also need to keep photovoltaic electric applied to other In the application of each photovoltaic cell current balance type of pond group.
Further, photovoltaic cell 140 is connect by conducting wire with the battery output balancing unit outside seal, and the conducting wire Hermetically passing seal, and insulate with seal.For example, after electric wire is pierced by seal, the megohmite insulants such as silicon rubber can be passed through Gap between electric wire and seal is sealed, to ensure the overall tightness of seal.

In this way, heat-conduction circuit board 130 breaks down when needing replacing, the company between heat pipe 150 and thermoconductive material board 120 is not interfered with It connects.Preferably, the first solder and the second solder are alloy material.
Heat pipe 500 is welded on thermoconductive material board 200 specifically, solder of the fusing point more than 180 DEG C can be first passed through, is selected Photovoltaic cell and heat-conduction circuit board are welded with solder of the fusing point more than 180 DEG C.It can will be led by the alloy that fusing point is 140 DEG C Heater circuit plate 130 is welded on thermoconductive material board 120.At this moment it only needs to be heated to about 160 DEG C with thermostatic platform can to weld or more Change photovoltaic cell and heat-conduction circuit board component.At this moment temperature is less than 183 DEG C, so in this welding process, heat pipe 150 and heat conduction Welding between plate of material 120 will not be destroyed, and the welding between battery and heat-conduction circuit board 130 will not be destroyed.In this way The photovoltaic cell for not only facilitating and being individually replaced and being welded on heat-conduction circuit board 130 is done, while the thermal coefficient of solder is about 60W/m ° of K, and the attainable maximum thermal coefficient of heat-conducting glue institute is about 3W/m ° of K, it is seen that doing so significantly improves heat transfer item Part.
