Specific embodiment
Fig. 1 is the weak wind charging technique one embodiment of dim light of the present invention, is explained further below by taking photovoltaic generation as an example
Where attached drawing and invention, if wind-power electricity generation then needs the AC rectification that will be sent to be filtered into direct current output.
There are tri- dotted line frames of A, B, C in circuit diagram shown in Fig. 1, the circuit in A dotted line frames is window comparator, B dotted line frames
Interior circuit is booster, and the circuit in C dotted line frames is Synchronization Control.
First explain the function of the A dotted line frames as window comparator.If the DC voltage that photovoltaic generation is sent is Uin（With
Lower abbreviation Uin is input voltage）, wherein（1）It holds as anode,（2）It holding as cathode, input voltage Uin is window comparator power supply,
Window comparator can perceive the height of Uin voltages.If light is stronger, input voltage Uin is higher than some voltage value, for electric power storage
Pond charges normal, this value agreement is referred to as upper threshold values；Either light is very weak（Such as night）, input voltage Uin is less than certain
A voltage value, this value agreement are referred to as lower threshold values；All forbid the booster circuit and C void in B dotted line frames in both cases
Synchronization control circuit work in wire frame.Only when the value of input voltage Uin is between lower threshold values and upper threshold values, then start B
Synchronization control circuit work in booster circuit and C dotted line frames in dotted line frame.
Window comparator physical circuit in A dotted line frames is as follows：The anode of one end connection input voltage Uin of resistance R1
（1）, one end of the other end connection resistance R2 of resistance R1, the cathode of the other end connection input voltage Uin of resistance R2（2）；PNP
The anode of the emitter connection input voltage Uin of triode V2（1）, one end of the collector connection resistance R3 of triode V2, electricity
One end and one end of capacitance C1 of the other end connection resistance R4 of resistance R3 and the series connection node of resistance R1 and resistance R2（3）, it is
Description facilitates meter, node（3）Agreement is known as " divider node ", and the other end connection input voltage Uin's of capacitance C1 is negative
Pole（2）；The anode of one end connection input voltage Uin of resistance R5（1）, the cathode of the other end connection voltage-stabiliser tube VD1 of resistance R5
With the base stage of triode V2, one end of the anode connection resistance R6 of voltage-stabiliser tube VD1, the other end connection adjustable essence in three ends of resistance R6
One end of the cathode K and resistance R0 of close voltage reference N1, the anode A of three end adjustable precision voltage reference N1 and resistance R0's is another
The cathode of end connection input voltage Uin（2）, the reference R of the three end adjustable precision voltage reference N1 of other end connection of resistance R4；From
The series connection node of the cathode K of the other end of resistance R6 and three end adjustable precision voltage reference N1（4）Enable signal control is drawn to rise
Depressor starts or stops, and facilitates meter for description, node（4）Agreement is known as " enabled node ".
Element model TL431 marked as N1, is three end adjustable precision voltage references, which has cathode K, anode A
With reference tri- pins of R.The present embodiment by N1 element accommodations make comparisons device use, work as divider node（3）Voltage be higher than 2.5 volts
When, N1 element conductives enable node（4）Just it is in low level state；Otherwise work as divider node（3）Voltage be less than 2.5 volts when,
N1 elements end, and enable node（4）Just it is in high level state.
Resistance R1 and resistance R2 series connection is followed by the both ends of input voltage Uin, and photovoltaic cell is issued in different illumination intensity
The voltage swing gone out is different, sampling voltage of the partial pressure as input voltage Uin on resistance R2.If input voltage Uin is sufficiently high,
Divider node（3）Voltage can reach 2.5 volts or more, N1 element conductives can be made, enable node（4）Just it is low level；Otherwise
N1 elements are cut-off state, enable node（4）Just it is high level.
In the case where triode V2 ends, divider node（3）Voltage U3 = Uin [ R2/（R1+R2）], to make
U3It >=2.5 volts, then must Uin=U1≥2.5 [ 1+（R2/R1）] volt, this U1Lower valve of the voltage value as input voltage Uin
Value.Once U3>=2.5 volts, enable node（4）Just it is low level, the appropriate voltage stabilizing value for choosing voltage-stabiliser tube VD1 makes U1Voltage is at this time
Voltage-stabiliser tube VD1 can be punctured, then triode V2 just obtain base current and turn on [base current by（1）The transmitting of end → V1
Pole → voltage-stabiliser tube VD1 → resistance R6 → N1 elements TL431 →（2）End], ignore the conduction voltage drop of triode V2, at this time resistance R3
With resistance R1 into parallel relationship, if the value after resistance R3 is in parallel with resistance R1 is Rr, and Rr ＜ R1.To keep U3>=2.5 volts,
It then must Uin=U2≥2.5[1+（R2/Rr）] volt.Due to Rr ＜ R1, so U2＞ U1, this U2Voltage value is as input electricity
Press the upper threshold values of Uin.
As threshold values U on input voltage Uin ＞2When, divider node（3）On voltage U32.5 volts of ＞ enables node（4）Just it is
Low level, due to enabling node（4）The start-stop controlling switch " EN " of integrated circuit QX5305 is connected, start-stop controlling switch " EN " is also
For low level, booster is forbidden to work.If as threshold values U under the voltage Uin ＜ that photovoltaic cell is sent1When, due to U1Voltage value is less than normal
Voltage-stabiliser tube VD1 cannot be punctured, start-stop controlling switch " EN " is similarly low level, booster is forbidden to work.
When the value of input voltage Uin is between lower threshold values U1With upper threshold values U2Between when, divider node（3）On voltage U3＜
2.5 volts, enable node（4）For high level, the start-stop controlling switch " EN " of integrated circuit QX5305 is also high level, starts boosting
Device works.
Secondly the function of the B dotted line frames as booster is explained.Booster circuit is chosen integrated circuit QX5305 and is controlled
Chip is the application circuit of QX5305 recommended by the manufacturer in B dotted line frames.There is the integrated circuit species of boost function very in fact
It is more, as long as there is start-stop controlling switch " EN ", it is not necessary to be confined to QX5305.Resistive element R01 ~ R06, electricity in B dotted line frames
Hold element C01 ~ C05, voltage stabilizing tube elements VD01 ~ VD02, inductance component L 01, field-effect tube element V02, integrated circuit
QX5305 etc. is that booster circuit institute is required.The function of the dotted line frame is exactly that input voltage Uin is increased to one suitably
Numerical value simultaneously stablizes output, makes it to charge a battery.One end of inductance L01 and the drain junction of field-effect tube V02（5）Make
For the anode of booster output voltage, tie point（5）And the anode of final output voltage Uout, the cathode of the booster is still
It is the cathode of input voltage Uin（2）, the size of output voltage determines by the ratio of resistance R05 and resistance R06.Because it is existing
Technology just repeats no more.
Thirdly explain the function of the C dotted line frames as output Synchronization Control.If conventional booster circuit, and be not required to
The circuit in C dotted line frames is wanted, it only need to be in one end of inductance L01 and the drain junction of field-effect tube V02（5）It is disconnected at end,
（5）The anode of one Schottky diode VD03 of end connection, the cathode of Schottky diode VD03 and the cathode of voltage-stabiliser tube VD02
It is connected and is used as the anode of final output voltage Uout, as Fig. 2 is represented.But the conducting pressure of Schottky diode
It drops larger, causes to be lost larger.Because the electricity sent under the weak landscape condition of dim light is originally faint, to solve to improve electric energy efficiency of transmission
Problem specially removes Schottky diode VD03, and uses the synchronization control circuit in C dotted line frames instead.Because of the conducting of field-effect tube
Pressure drop very little can substantially reduce loss after substituting Schottky diode.Physical circuit is as follows：Cathode, the voltage-stabiliser tube of diode VD3
The anode of the cathode of VD5 and one end connection final output voltage Uout of capacitance C2（5）；The anode connection of diode VD3 is steady
The cathode of pressure pipe VD4, the cathode of the anode connection input voltage Uin of voltage-stabiliser tube VD4（2）；The anode connection resistance of voltage-stabiliser tube VD5
One end of R7, the anode of the other end connection diode VD6 of resistance R7, the cathode connection N-channel field-effect tube V1 of diode VD6
Grid and PNP triode V3 emitter, the collector of triode V3 connects input voltage Uin with the source electrode of field-effect tube V1
Cathode（2）；The base stage of triode V3 be connected to the anode of diode VD3 on the cathode of voltage-stabiliser tube VD4 this series connection node,
The base stage of triode V3 be also connected to the other end of resistance R7 on the anode of diode VD6 this series connection node；Capacitance C2's
On the anode and this series connection node of one end of resistance R7 of other end connection voltage-stabiliser tube VD5；The anode of Schottky diode VD7 connects
Connect the drain electrode of field-effect tube V1, the source electrode of the cathode connection field-effect tube V1 of Schottky diode VD7；The drain electrode of field-effect tube V1
Cathode as final output voltage Uout（6）, load the anode that RL is connected to final output voltage Uout（5）And cathode（6）
Between.
It is as follows to export synchronization control circuit operation principle：Because the field-effect tube V01 in booster circuit is in "ON", "Off"
Work under state, that is to say, that turned on during field-effect tube V01, when and end.When field-effect tube V01 is in the conduction state
When, the electric current that input voltage Uin is generated flows through inductance L01 and field-effect tube V01, inductance L01 energy storage；It is appropriate to choose voltage-stabiliser tube
The voltage stabilizing value of VD5 makes the undertension on capacitance C05 at this time to puncture voltage-stabiliser tube VD5, then the grid dead electricity of field-effect tube V1 is cut
Only, load RL is obtained electric by Schottky diode VD7.When field-effect tube V01 is in cut-off state, input voltage Uin superpositions
Output voltage is raised after the induced potential of upper inductance L01, voltage-stabiliser tube VD5 can be punctured, through voltage-stabiliser tube VD5 → resistance R7 → bis- pole
Pipe VD6 is added on the grid of field-effect tube V1, and field-effect tube V1 conductings, load RL obtains electric.That is, V01 is on shape
V1 ends during state, and V1 is turned on when V01 be in cut-off state, and process is alternateed and synchronously carried out, therefore is known as " synchronous to control
System ".If booster is stopped, synchronization control circuit is equally stopped；Start booster work, synchronization control circuit
Also it is activated work.
Triode V3 scene effect pipes V01 is also conducting when turning on, it can discharge rapidly the grid of field-effect tube V1
The charge of extremely upper storage（Discharge path is base stage → diode VD3 → field-effect of emitter → triode V3 of triode V3
Pipe V01 → resistance R03）, the turn off process of acceleration field-effect tube V1.Voltage-stabiliser tube VD4 can prevent the grid of field-effect tube V1 from powering on
Press through high breakdown, capacitance C2 can accelerate the turn on process of field-effect tube V1.
The above is only that the preferable of the present invention implements example, not makees valve system in any form to invention, appoint
What those skilled in the art changed or be modified to possibly also with the technology contents of the disclosure above equivalent variations etc.
Embodiment is imitated, but it is every without departing from technical solution of the present invention content, and technical spirit according to the invention is to above example institute
