As shown in Figure 4; above-mentioned voltage-limiting protection circuit 423 comprises: zener diode D14; resistance R 5; resistance R 6 and aerotron VT2; resistance R 5 and resistance R 6 compose in series bleeder circuit successively; this bleeder circuit is connected across between the voltage input end and ground end of described storage battery BT1; being positioned at dividing potential drop on the resistance R 6 of below makes zener diode D14 conducting and provides bias voltage for the base stage of aerotron VT2; the positive terminal of zener diode D14 connects the base stage of aerotron VT2; the negative pole end of zener diode D14 connects an end of resistance R 6; the grounded emitter of aerotron VT2, the collecting electrode of aerotron VT2 connects the base stage of aerotron VT1 and the control end of ON-OFF control circuit.Be connected in series a current-limiting resistance R7 between the control end of the collecting electrode of aerotron VT2 and ON-OFF control circuit 402, be used to limit the electric current that is input to ON-OFF control circuit 402.Among Fig. 4, ON-OFF control circuit 402 is made of full control binistor, and it can comprise gate level turn-off thyristor, electric power thyristor, power transistor, electric power field effect transistor and igbt.The principle of work of foregoing circuit is as described below:
Solar cell SB1 is in use because the variation of sunshine is bigger, and its internal resistance is more higher again, so the output voltage instability, and this just needs with giving the charging of BT1 storage battery after DC transfer circuit 413 voltages of transformation, and DC transfer circuit 413 is seen Fig. 4.When aerotron VT1 conducting, the induced voltage of high-frequency transformer T1 primary winding 1,2 ends is 1 positive 2 negative, and output primary 5,6 ends are 5 positive 6 negative, and rectifier diode D13 is in off condition, and at this moment high-frequency transformer T1 is by primary winding 1,2 stored energy; When switching valve VT1 by the time, output primary 5,6 ends are 5 negative 6 just, the energy of storing among the high-frequency transformer T1 charges to BT1 after by D13 rectification and capacitor C 5 filtering.Aerotron VT1 can be the Switching Power Supply pipe, and it forms self-excited oscillation circuit with T1, R1, R2, R3, C4 etc.Behind solar cell SB1 out-put supply, electric current makes the VT1 conducting through the base stage that starting resistance R1 flows to aerotron VT1.After the aerotron VT1 conducting, voltage transformer T1 primary winding just adds input direct voltage, the linear growth in primary winding 1,2 ends of voltage transformer T1 of its collector current, primary winding 3,4 ends produce 3 positive 4 negative induced voltages as feedback coil, make aerotron VT1 obtain base stage for just, the very negative positive feed back voltage of emission, this voltage injects base current through C4, R3 to aerotron VT1 further increases the collector current of aerotron VT1, positive feed back produces avalanche process, makes aerotron VT1 saturation conduction.During aerotron VT1 saturation conduction, voltage transformer T1 stores magnetic energy by primary winding 1,2 ends.Meanwhile, induced voltage charges to C4, and along with increasing of C4 charging valtage, aerotron VT1 base potential is step-down gradually, can not satisfy it and continues when saturated when the base current of aerotron VT1 changes, and aerotron VT1 withdraws from the saturation region and enters the amplification region.After aerotron VT1 enters magnifying state, the maxim of its collector current before by magnifying state descends, produce 3 negative 4 positive induced voltages at primary winding 3,4 ends as feedback coil, aerotron VT1 base current is reduced, its collector current reduces thereupon, avalanche process appears in positive feed back again, and aerotron VT1 ends rapidly.After aerotron VT1 ended, voltage transformer T1 energy stored offered load, and the 5 negative 6 positive voltages that output primary 5,6 ends produce obtain the charging of vdc accumulators group BT1 storage battery on C5 behind diode D13 rectifying and wave-filtering.When VT1 ends, 3 negative 4 positive voltages of DC supply input voltage and the induction of primary winding 3,4 ends are given the C4 reverse charging through R1, R3 again, improve aerotron VT1 base potential gradually, make its conducting again, the upset state that reaches capacity once more, circuit repeats vibration like this and goes down.
Among Fig. 4, resistance R 5, resistance R 6, diode D14, aerotron VT2 etc. form voltage-limiting protection circuit 423, with the protection storage battery, are example with the 12V storage battery here, and its charging deboost is 14V.In the process of charging of storage battery BT1, storage battery BT1 voltage rises gradually, when charging valtage during greater than 14V, zener diode D14 begins conducting after R5, R6 dividing potential drop, make aerotron VT2 conducting, the shunting action of aerotron VT2 has reduced the base current of aerotron VT1, thereby has reduced the collector current Ic of aerotron VT1, has reached the effect of restriction output voltage.At this moment circuit has stopped the large current charge to storage battery BT1, with little electric current the voltage of storage battery is maintained 14V.On the other hand, because the conducting of aerotron VT2, make the current potential step-down of aerotron VT2 collecting electrode, it is low making the grid of switching valve VT3 by resistance R 7, switching valve VT3 is the N-channel MOS pipe, and it realizes the function of ON-OFF control circuit, when the grid of switching valve VT3 is low level, switching valve VT3 closes, and wind-power electricity generation assembly 401 just stops to charge to storage battery BT1.When the grid of switching valve VT3 is high level, switching valve VT3 is opened, wind-power electricity generation assembly 401 charges to BT1, at ordinary times when storage battery BT1 is not full of, wind-power electricity generation assembly 401 charges to storage battery BT1 simultaneously with solar cell, when storage battery BT1 is charged to 14V, owing to added the storage battery testing circuit, both can both the SELF CL charge circuit, to prolong the service life of storage battery BT1.
In sum, circuit structure provided by the invention is simple, and all adopt breakaway-element, can control discharging and recharging of storage battery automatically, do not need the control chip of additive incrementation costliness, so cost is low, practical, convenient for maintaining and replacing after the device failure.Device of the present invention can independently be the main storage battery bottle or the standby storage battery charging work of automobile, especially the mixture locomotive of new automobile storage battery car and fuel vehicle, its wind wheel Power Component can be installed in self-propelled vehicle top or car body below, and its solar battery group can be installed in self-propelled vehicle top or vehicle body side.When fuel oil exhausts or during the fuel vehicle system failure, electric flux depends on effect qualitatively, can accomplish to utilize wind wheel and solar power to charge while travelling, really accomplish not have and recycle, also can be under the bad terrible situation of automobile current generator, guarantee the normal of automobile storage battery, powered operation is provided for each load of locomotive.As vehicle-carrying communication calling system, vehicle netbios.In addition, also can be when automobile does not travel and uses with the automobile wind wheel towards the wind direction is arranged, form a mobile wind wheel generation system.The present invention can also apply on the high speed train, and it is installed and also is conveniently.
Should be understood that, for those of ordinary skills, can be improved according to the above description or conversion, and all these improvement and conversion all should belong to the protection domain of claims of the present invention.
