Detailed description of the invention
As in figure 2 it is shown, the present invention includes frequency-adjustable alternating current power supply, two groups of resonator systems, plates capacitance and two conductors
Four parts.Transmitting terminal is by high-frequency ac power, transmitting terminal resonator system, plates capacitance C2E plate and conductor 1 form；Receiving terminal
By receiving terminal resonator system, plates capacitance C2F plate, conductor 2 and load composition.Transmitting terminal resonator system includes inductance L1And adjust
Humorous electric capacity C1, high-frequency ac power forms series loop, plates capacitance C with transmitting terminal resonator system2E plate and electric capacity C1A end
Connect, electric capacity C1B end be connected with conductor 1；Receiving terminal resonator system includes inductance L3And tuning capacity C3, receiving terminal resonance system
System forms series loop, plates capacitance C with load2F plate and electric capacity C3C end connect, electric capacity C3D end be connected with conductor 2；
Plates capacitance C2E, F plate the most right.Transmitting terminal and receiving terminal are wireless connections, only carry out energy transmission by plates capacitance.
Conductor 1, conductor 2 are equivalent to two ground capacities relative to infinite point.Higher-order of oscillation system is under resonance condition
Can be at electric capacity C1With inductance L1Junction A point produce the voltage of bigger high-frequency and high-voltage, this high frequency voltage is guided to plates capacitance
C2E end time, plates capacitance and conductor 1, two direct-to-ground capacitance of conductor 2 form loops, plates capacitance C2E, F two ends will
Produce high-frequency electric field, thus produce faradic current.Under the driving of high-frequency electric field, the high frequency voltage that resonator system produces makes pole
Produce high-frequency electric field between plate electric capacity, between plates capacitance, produce fast-changing faradic current I2, by receiving terminal electric capacity C3Time, meeting
At C3Upper generation is with the induced voltage of frequency, and causes receiving terminal loop C3-L3-RLLoop resonance, thus receiving terminal load on
Produce bigger electric current and consume bigger power.So, transmitting terminal provides energy, receiving terminal and load consumption energy, it is achieved
Being wirelessly transferred of electric energy.
In the present invention, the faradic current I in transmission loop2Amplitude is less, is in mA rank, thus in transmission loop
Being difficult to produce power, therefore system is less demanding to the parasitic resistance in transmission loop, even if transmission capacitor loop resistance very big (as
5k Ω) also will not significantly affect the efficiency of transmission of system, the most in actual use, use the common metal such as aluminium-foil paper, iron plate
Material structure plates capacitance.This is also an important feature of the present invention.
In the present invention, plates capacitance C2Capacitance the least, about 3～6pF, conductor 1, conductor 2 for infinite point
Virtual earth electric capacity is about 30～60pF, and in the loop that plates capacitance and virtual earth electric capacity are formed, virtual earth electric capacity is relative to plates capacitance
Capacitance relatively big, therefore virtual earth electric capacity does not produce main impact to system transfers efficiency, and energy mainly transmits between plates capacitance.
The make of virtual earth electric capacity has a variety of, and the isolated conductor of line, plate, block, ball etc. can be used to construct virtual earth electric capacity.
Choosing of step one high-frequency ac power
Alternating current power supply need to possess following three points feature:
1) frequency stable.Long-time stable can be operated in the resonant frequency of system, and the fluctuation of frequency must be use up
That measures is little.
2) frequency-adjustable.Owing to the coil of coiling or the electric capacity produced cannot ensure completely the same, system building ring
Border would also vary from, so the resonant frequency of different wireless energy transfer systems can not be identical.The power supply of design
Need to adapt to different system, i.e. frequency must be adjustable.
3) internal resistance is low.In order to reduce the energy that high-frequency ac power is consumed, it is necessary to select the power supply that internal resistance is less.
Based on requirements above, the alternating current power supply that the present invention uses is made up of DC source and inverter circuit, and select inverse
Power transformation road is with the function of manually regulation operating frequency, and this not only can facilitate the working effect seen intuitively under different frequency,
Also the high-frequency ac power selected is made to be adapted to different systems.
Choosing of step 2 resonator system
The resonator system that the present invention selects selects low internal resistance, the coil system of high q-factor.Coil resistance is low, and system obtains relatively
Big faradic current, when producing higher electromotive force for high internal resistance so that have higher electric field energy in the middle of plates capacitance.Work as line
Circle internal resistance one timing, selects the coil of high q-factor can reduce the active power consumption of system impedance, thus obtains higher transmission
Efficiency.
The realization that step 3 electric capacity conducts electricity
As in figure 2 it is shown, the two of plates capacitance used in the present invention pieces of pole plates are the most right, can be selected for such as masking foil, iron plate etc.
Simple material, plates capacitance E plate meets electric capacity C1A end, corresponding plates capacitance F plate meets electric capacity C3C end, electric capacity C1,
C3B, D end respectively earth conductor 1 and conductor 2.
If Fig. 4 is equivalent circuit diagram of the present invention.In the present invention, resonant capacitance two ends are connected with conductor, conductor and infinity
Place constitutes electric capacity, and this is equivalent to by plates capacitance C2With the two virtual earth electric capacity C being connected in seriesg1,Cg2Form transmission loop, make pole plate
Electric capacity C2Middle generation faradic current I2, but energy transmission between two conductors, can not be carried out, if the electric capacity that conductor is constituted with infinite point
Capacitance the least, the equivalent capacitive reactance of conductor will be very big, and therefore the equivalent capacitance of conductor is the lowest, consume the energy on conductor more
Many, the energy transmitted by plates capacitance is the fewest, and efficiency of transmission is the lowest or not be enough to drive loaded work piece, therefore needs to select
The conductor that equivalent capacity is bigger.In air, radius is the isolated conductor ball of R, is C relative to the capacitance calculation formula of infinite pointg
=4 π ε0R, wherein ε0=8.85 × 10-12Being permittivity of vacuum, R is conducting sphere radius.When in conductor, the knots modification of electric charge is
During Δ q, its electromotive force knots modification isIsolated conductor ball is when electric charge changes, and electric charge changes more obvious, unfavorable
Work in system, therefore need to select electromotive force knots modification little, the conductor of the shape that the capacitance of equivalent capacity is big.
Such as Fig. 5, for plates capacitance schematic diagram.Solid arrow be high frequency voltage when positive half period, dotted arrow is high frequency
Voltage is when negative half-cycle, and the rapid of the electric charge on plates capacitance two-plate converts, and produces fast-changing electric current, thus realizes
The transmission of energy.Plates capacitance computing formula isA is the area of capacity plate antenna, and d is the distance of two capacity plate antennas, pole
The capacitance of plate electric capacity is the least, is only that pF level achieves that and makes energy transmit between plates capacitance by field coupling.The higher-order of oscillation
At the resonant frequency fx, conductor has bigger electric capacity relative to infinite point to system, and energy transmits between plates capacitance, thus drives
Dynamic load works.
By setting up Kirchhoff's equation at working frequency range:
Wherein R1=RC1+RL1+Rp, R3=RC3+RL3+RL, RpFor the internal resistance of source, RC1,3,RL1,3It is respectively resonator system electric capacity
And inductance internal resistance.
Draw through derivation Kirchhoff's equationObtain through-put power PO
=| I3|2RL.Wherein R1=RC1+RL1+Rp, R3=RC3+RL3+RL。
After present system is sequentially connected with, opens alternating current power supply, system now produces faradic current, because high frequency is made
With, between electric capacity and inductance, produce high frequency voltage, plates capacitance produces faradic current immediately.Reception used herein with send out
Penetrating resonator system natural frequency consistent, energy transmits between plates capacitance, and drives receiving terminal resonator system to resonate, and passes through rectification
After the circuit high-frequency electrical energy to receiving carries out rectification, drive loaded work piece.Now the frequency of alternating current power supply is adjusted, makes
The system of obtaining works at different frequencies, and the faradic current that system produces, induction electromotive force all changes, the electricity that load-receipt arrives
Can be also different.For making system can obtain higher service behaviour, it is only necessary to regulation operating frequency makes reception electric current maximum.
