Description
Technical field
The invention belongs to collection of energy and management electronic circuit and quick charge field, and in particular to a kind of common based on broad sense
Quick, efficient, the boost charge method shaken.
Background technology
Classical theory is impedance matching for the peak efficiency principle of electric energy transmission/acquisition.It means：In the energy has
When hindering R, " load resistance " that load obtains peak efficiency should also be equal to R.As shown in accompanying drawing 1-1~accompanying drawing 1-4：When the sky of the energy
When carrying " open-circuit voltage " for 10V, internal resistance RN=5 Ω, only load resistance RW=5 Ω could obtain " bearing power " of maximum
=5W, but energy source power=10W, energy in-fighting=5W, the utilization rate of the energy is only 50%.
But when being charged with alternative energy sources to super capacitor or/and battery, such as accompanying drawing 1-4, it is most of under the conditions of the energy
Impedance is extremely low, and the apparent impedance of load (super capacitor and battery) is change, can be sayed without impedance matching.Particularly,
Classical charging energy-storing technology is to be directly over rectification to the energy source voltage of exchange to charge to electric capacity or/and battery for direct current,
Two limiting conditions present in it are：
A, " load voltage " of energy storage is always lower than the energy " open-circuit voltage ", such as accompanying drawing 1-5, accompanying drawing 1-6；
B, when energy open-circuit voltage is less than the load voltage of energy storage, charging stops, and charging effect is zero.
The limitation of the above-mentioned limit, causes the problem of (being to AC rectification) DC energy storage charging of classics brings serious：
The peak value of alternative energy sources voltage can not be to charging accumulator when being pressed less than storing up electricity so that the even valuable energy obtained is not
Can storage utilization；Energy-storage capacitor CC limit energy storage electricity Q, depending on highest energy source voltage UI：Q≤UI*CC.
Due to above-mentioned limitation, if electric car needs about 1000V voltages, classical rectification charging method uses 220VRMS
The common frequency power network energy of (311Vp) can only be charged to 310Vp to energy storage super capacitor, have no alternative but take to multiple super capacitors
Charged in parallel (arrive 310V), again with the series connection of multiple (such as 3) super capacitors to load supplying (exporting 930V).Thus bring
Charged in parallel, the cumbersome control problem of series connection electricity utilization conversion, moreover, the peak value of N number of capacitance C identicals electric capacity charged in parallel
Electric current is N times of single electric capacity；And in order to reduce charging peaks electric current, it is necessary to the longer charging interval.This brings not again
Quick charged problem.
Due to the limitation of above-mentioned classical rectification charging method, also result in environmental energy without (electricity) source radio-based electronic devices
When the energy source voltage UI for being transformed to the power supply acquisition device of electric energy is charged to UCC to storage capacitor CC close to UI voltages, it is impossible to
Storage capacitor is continued to charge；, can not when storage capacitor CC voltage UCC is more than the energy source voltage UI of power supply acquisition device
The energy is continued with charging and increase energy storage；When energy-storage battery E voltage UE is more than the energy source voltage UI of power supply acquisition device
When, the energy can not be continued with charging and increase energy storage.
Main Means of the prior art when solving the problems, such as high efficiency charging, energy storage are the pressure drops for reducing rectifier, are such as made
With Schottky diode (its Typical pressure drops be 0.2V, and the Typical pressure drops of general-purpose diode are in more than 0.7V), even with
VMOS triodes (its Typical pressure drops about 0.01V) rectification of logic circuit control is detected, but still can not be solved to storing up electricity pressure
The problem of storage capacitor CC or battery E of VCC, VEE higher than energy source voltage UI continue to charge；And solve low-voltage energy rectification
The Main Means that the low-voltage of gained charges to high-tension storage capacitor or battery are the DC/DC converters using booster type,
Still can not solve from the energy try one's best obtain energy the problem of.
Asked accordingly, it would be desirable to solve, efficient, boost charge quick to energy storage device (super capacitor or/and rechargeable battery)

96.41V is only needed 0.06 second, and final " tank voltage " is 755V after 1s, higher than " open-circuit voltage " 100Vp of the energy；In storage
The work(that can store on electric capacity CC, can be 286W.
Compare above-mentioned data, it is seen that after 1 second charges, quick, efficient, the boosting based on generalized resonance of the present invention is filled
Method for electrically is compared with classical charging modes, average 287/4.48=64 times of the power ascension of charging, tank voltage lifting 755/96.41
=7.83 times, 286/4.65=61 times of the energy lift of storage charges to the speed lifting 1/ of the final voltage of classical charging eventually
0.06=16 times.The simulated effect shows：Generalized resonance boost charge method, solves " the storage present in classical charging method
Can voltage " it is always lower than the energy " open-circuit voltage ", and energy open-circuit voltage, when being less than " tank voltage " of energy storage, charging stops
Only, the problem of charging effect is zero.
Quick, efficient, boost charge method the general principle based on generalized resonance of the present invention is：
Implementing during the boosting of RLC generalized resonances, when resonant capacitance C voltage occurs close to (deviation is not more than
5%) voltage of peak value, when the tank voltage higher than storage capacitor CC adds the rectifier pressure drop of rectification charging accumulator, comes from
The electric current of alternative energy sources is no longer supplied separately to LC resonance energy storage, and mainly turns to rectifier rectification and then filled to storage capacitor CC
Electricity.This instantaneous alternative energy sources electric current, equal to instantaneous energy open-circuit voltage resistance in the pressure drop divided by the energy on internal resistance R
R；Can ource electric current some still flow through L, flow into electric capacity C electric current its " void " power, be stored in LC and strengthen its broad sense
Resonance, they are simultaneously not regarded as useful (reality) work(consumption, but continue to realize that generalized resonance boost charge is done for next cycle
Prepare, until resonant capacitance C crest voltage is increased to (the boosting coefficient determined by RLC parameter designings XL=XC=G*R) G
Stop during " open-circuit voltage " peak value of times energy.
Due to the phase of the L and C of RLC series resonant circuits terminal voltage, compared with 90 degree of current and phase difference, so, in generation

Tank voltage 362.22V：(364.77-362.22=2.55V=2 1.29V), is two rectification tube voltage drops in rectifier, in
It is to have situation 4：Energy ource electric current 8.32A from power supply is no longer supplied separately to LC resonance energy storage (situation 2：0.921A), it is and main
Turn to rectifier and storage capacitor CC (situations 2：Charging current 7.4A, 7.4+0.921=8.321=can ource electric currents 8.32！).This

Accompanying drawing 2-2, such as Fig. 2-3, accompanying drawing 2-4 are emulation testing figures.
The parametric statistics that emulation testing is obtained is compared as follows：
Emulate data analysis visible：Generalized resonance boosting (resonance step-up) mise-a-la-masse method has charging than classical way charging
Speed is fast, charging voltage is high, energy storage energy is more, it is allowed to be interrupted (every 10 seconds charge 2 seconds) so as to save wireless power " railway roadbed without
Line charger N1 " length and largely save construction investment (being for example reduced to about 1/5), and proof load can be met requirement
Voltage, improve the superiority such as charge efficiency.
In another example：The energy getter powered for wireless senser getable energy source voltage UI be humble often
Shown in " classics charging and the resonance step-up charging circuit figure " of voltage, such as accompanying drawing 2-5, energy source voltage UI=0.1Vp contains internal resistance
R1=10m Ω and internal inductance L1=1mH.When classical charging modes with energy source voltage UI are directly over bridge rectifier GR2
When rectification is charged to storage capacitor CC2=1F, because the conducting voltage of bridge rectifier needs about 1.2V, therefore, such as accompanying drawing 2-6
It is shown, by discharging 100 seconds after 100 seconds " charging ", due to the input voltage also only UC2=0.1Vp, institute of bridge rectifier
The voltage VCC2 ≈ 0 obtained with storage capacitor CC2, storage capacitor CC2 there is no charge power and work(.And pass through broad sense and be total to
Shake step-up method, and CC1 obtains whole voltage VCC1=1.41V, and the work(of storage reaches 4.31*200=862mW*s.
The reason for classical charging effect of above-mentioned example is 0 is：Energy source voltage UI can not be carried using classical charging method
Voltage UC2 required for for being turned on higher than bridge rectifier.One of lifting UC2 most simple and effective approach is solved, is to utilize
The existence conditions (containing R1 and L1) and RLC generalized resonance principles of the energy.Such as accompanying drawing 2-5 generalized resonance test emulation circuit institute

R1L1C1 series resonant circuits.Fig. 2-6 test shows：When being charged to 100 seconds, the voltage of bridge rectifier RG1 inputs
UC1=2.99V, it is sufficient to make RG1 turn on and be charged to energy-storage capacitor CC1.
Resonant capacitance C1 design methods is make series resonance frequency FD, equal to the frequency FN of alternative energy sources voltage.If the energy
Frequency FN=500Hz, according to formula F D=1/ ((LC)0.52 π), calculate C1=1/ (2 π FD)2L1=
101.3211836uF, approximately take C1=100uF.
The R1L1C1 generalized resonance natural laws are：Can be constantly continuous (such as in the energy of this circuit) from nature
Obtain the energy that causes generalized resonance and with generalized resonance (i.e. by its generalized resonance frequency FD vibration) in the way of be stored in it
In L1C1 devices, and the resonant inductance L1 and resonant capacitance C1 of its R1L1C1 generalized resonance circuit terminal voltage is set constantly to increase,
Until vibration electric current on the resistance R1 of R1L1C1 generalized resonance circuits consumption power be equal to from the energy obtain power when
Stop rising.Add the storage on storage capacitor CC1 when the pressure drops for being more than bridge rectifier of the voltage UC1 between resonant capacitance C1 two ends
