A non-resonant state close to the resonance state, a load Q value of 50 or less, a voltage fluctuation rate at the time of load of 50% or less, and mutually circulating the exciting current flowing through the feeding coil 11 to an AC power source It is assumed that the load on the power supply coil 31 is reduced, the radiation of the electromagnetic wave signal radiated from the feeding coil 11 is suppressed, and the variable magnetic field is efficiently radiated to the outside.
The inductive reactance of the feeding coil 11 and the capacitive reactance of the phase adjusting means 34 connected in series are in a non-resonant state, in a non-resonant state close to the resonance state, and a load Q of 50 or less. A voltage fluctuation rate under load of 50% or less, which improves the power factor of the effective load current flowing through the feeding coil 11 and suppresses the emission of electromagnetic wave signals radiated from the feeding coil 11 To do.

Further, the inductive reactance of the power receiving coil, the capacitive reactance of the phase adjusting unit 64 connected in series with the power receiving coil, and the capacitive reactance of stray capacitance existing around the power receiving coil are in a non-resonant state. It is in a non-resonant state close to the resonance state, has a load Q value of 50 or less, a load voltage fluctuation rate of 50% or less, suppresses re-radiation of electromagnetic wave signals, and is radiated from the feeding coil It is assumed that an electromotive force is efficiently induced from a varying magnetic field and effective power is supplied to the power storage means 61.
Further, the power distribution means 33 directly supplies the power supply coil 11 with AC power having a frequency exceeding 50 Hz to 41 MHz, drives it through a transformer, and supplies the phase control means connected in series for phase control. The devices are connected in parallel and supplied, driven through a reactor, driven by converting the frequency, or a combination of these to drive a large excitation current and radiate a high-power fluctuating magnetic field from the feeding coil The power receiving means 63 directly outputs the electromotive force induced in the power receiving coil 41, and outputs it via a transformer. The phase adjusting means is connected in series and output, and the frequency is converted and output. Impedance converted and output, converted to DC voltage by rectifier 62 and output, output to power storage means, or combined to output as a large current power source, and contactless as a whole Constituting the collector.

Here, when the voltage of the AC power source for driving the feeding coil 11 is Ein * Sin (ωt), the inductance of the feeding coil 11 is L1, and ω = 2πf = the angular frequency of the varying magnetic field, the input terminals 21a, 21b The excitation current Iin (A) supplied to the capacitor is Iin = (Ein / ωL1) Cos (ωt), which is a large excitation current. Therefore, the phase adjusting means 32a and 32b are connected in parallel to the input terminal side of the feeding coil. Thus, the excitation current flowing through the AC power source is circulated between the phase adjusting means 32a and 32b connected in parallel with the power supply coil, and the load power factor is improved by the power supply coil 34 connected in series with the power supply coil. In this state, a large excitation current can be supplied to the feeding coil.

The feeding coil, the phase adjusting means 32a and 32b, and the stray capacitance existing around the feeding coil are in a non-resonant state, in a non-resonant state close to the resonance state, and the load Q is 50 or less. The load voltage fluctuation rate is 50% or less, or a combination thereof, thereby suppressing the emission of electromagnetic wave signals, efficiently radiating fluctuating magnetic fields, and propagation loss of electromagnetic wave signals in the atmosphere. It is possible to perform non-contact power feeding and magnetic wave communication in a substance that is large compared to the propagation loss of water, in fresh water or seawater having a salinity of 0% to 10%, or in a combination thereof.

In addition, the radius of the feeding coil is a1, the area is S1, the number of turns is N1, the relative permeability of the magnetic material is μe1, and the magnetic flux density B generated at a distance Z (m) from the point of the feeding coil 11b is: When the feeding coil and the receiving coil face each other in the horizontal direction and the relative distance is represented by D = (a1 ^ 2 + Z ^ 2) ^ (1/2), according to Bio-Savart's law,
B = {(Ein / ωL1) * (μ0 * μe1 * N1 * S1) / [2π (a1 ^ 2 + Z ^ 2) ^ (3/2)]} Cos (ωt) = {(Ein / ωL1) * (μ0 * μe1 * N1 * S1) / (2π * D ^ 3)} Cos (ωt) －－ （1）
It becomes.

Therefore, when the feeding coil and the receiving coil are circular coils, the inductance of the feeding coil can be obtained from L1 = 1.94 * 10 ^ -6 * μe1 * N1 ^ 2 * S1 as an approximate expression, and the number of turns of the receiving coil Is N2, the area of the receiving coil is S2, μ0 = 4π * 10E-7, and the relative permeability of the magnetic material of the receiving coil is μe2, the electromotive force Eout induced in the receiving coil is Faraday's From the law of electromagnetic induction,
Eout = -dΦ / dt = -N2 * S2 * dB / dt = {[(Ein / 10) * (μe2 * (N2 / N1) * S2)] / D ^ 3]} Sin (ωt)-(2 )
Since it has the same phase as the voltage of the AC power supply and does not include ω in the amplitude term, it has a wideband characteristic. Therefore, if the electromotive force is output as it is using a source follower circuit, it can be used as a magnetic wave antenna for digital communication. Indicates that they can also be shared.

However, in order to use the power receiving coil for contactless power feeding, it is necessary to output effective power from the electromotive force, and the relationship between the reactance ωL2 (Ω) of the power receiving coil and the internal resistance R (Ω) of the power storage means Is ωL2 <R, even if the power receiving coil is in a non-resonant state, the current Iout (A) flowing through the power storage means is
Iout = Eout / (R + jωL2) ≒ Eout / (R) = {[(Ein / (10 * R)) * (μe2 * (N2 / N1) * S2)] / D ^ 3} Sin (ωt) − -(3)
Thus, an effective current flows through the power storage means, and can be applied to non-contact power feeding in the air or in seawater.
On the other hand, when the relationship ωL2 <R is not satisfied, the load power factor of the current Iout (A) flowing through the power storage unit is reduced, which causes a problem that power supply efficiency is reduced.

Therefore, when the phase adjusting means having a reactance of (1 / ωC2) is connected in series to the power receiving coil and (1 / (ω ^ 2 * L2 * C2)) ≈1, the current Iout (A )
Iout = Eout / (R + jωL2 (1- (1 / (ω ^ 2 * L2 * C2))) ≒ Eout / (R) = {[(Ein / (10 * R)) * (μe2 * (N2 / N1) * S2)] / D ^ 3} Sin (ωt) －－ （4）
Thus, a charging current having the same phase as the electromotive force flows through the power storage means, and effective power is output.
In the above equation (4), even when the phase adjusting means is connected in series, the case where the power receiving coil satisfies the case where ωL2 (1- (1 / (ω ^ 2 * L2 * C2)) <R holds. The power receiving coil is in a non-resonant state close to the resonance state, the load coil Q value (ωL2 / R) of the power receiving coil is 50 or less, and the resonance frequency of the power receiving coil is It is in a state lower than the frequency of the alternating current power supply to be driven, the voltage fluctuation rate at the time of load is 50% or less, or the combination thereof, the electromagnetic wave signal re-radiated from the power receiving coil is suppressed. Non-contact power supply is possible.

In addition, the power supply coil is wound in close contact with a magnetic body, and when a large current is driven to the power supply coil, the magnetic flux density Br (r (m) point from the power supply coil toward the center point ( Tesla) is expressed by Br = μ0 * μe1 * N1 * Iin / 2r, and when r≈0, when the supply current Iin (A) increases, the magnetic flux density easily increases the saturation magnetic flux density of the magnetic material. Therefore, it is necessary to be air-centered at least near the coil.
In addition, in order to supply a large amount of power in a non-contact manner, both the power supply coil and the power receiving coil are air-core so that the magnetic flux density is not saturated by a large current, and the magnetic flux density is not saturated by a large current. The magnetic flux density is not saturated, or a combination thereof, and the magnetic flux density of the varying magnetic field radiated from within the area of the feeding coil is made to be uniform, the electromotive force induced from the power receiving coil is made to be uniform, Or these measures are needed.

Here, when the effective power is output from the power receiving coil, the equivalent effective power is supplied from the AC power source, but the reactance ωL1 (Ω) of the power supply coil and the internal resistance R (Ω ) And ωL1 <R, the load power factor for the AC power supply is high and the power supply efficiency is good.However, when the relationship ωL2 <R is not satisfied, the reactance of the power supply coil is (1 / It is necessary to take measures by connecting the phase adjusting means 34 of ωC1) in series.
Further, even when the phase adjusting means 34 is connected in series with the feeding coil, ωL1 (1- (1 / (ω ^ 2 * L1 * C1)) <R is established, and the feeding coil is close to the resonance state. It is in a non-resonant state, the output impedance of the AC power supply is made lower than the load impedance, the reactance of the feeding coil is reduced, the load Q value (ωL1 / R) of the feeding coil is 50 or less, and the resonance of the feeding coil If the frequency is lower than the frequency of the alternating-current power supply to be driven and the voltage fluctuation rate under load is 50% or less, or a combination thereof, the electromagnetic wave signal radiated from the feeding coil is suppressed. Non-contact power feeding in the inside becomes possible.

Further, the power distribution means 33 is added with functions of starting and stopping the AC power supply, collecting billing information, switching a plurality of sets of feeding coils, combining a plurality of sets of feeding coils, or a combination thereof.
In addition, since the electromotive force induced in the power receiving coil changes due to the change in the interval between the power feeding coil and the power receiving coil, a sensor is provided to constantly monitor the electromotive force, and tap switching of the power receiving coil and tap switching of the reactor are performed. Further, it is necessary to adjust and control the tap switching of the phase adjusting means, the pulse width of the AC power source for driving the feeding coil, or a combination thereof.

Further, when the power feeding coil is embedded under the road surface or the power receiving coil is mounted on an EV vehicle, a non-magnetic good conductor plate is disposed on the lower surface of the power feeding coil or the upper side of the power receiving coil. The effect of reducing the eddy current loss generated in the object existing in the vehicle body or the vehicle body of the EV vehicle and increasing the radiation of the variable magnetic field in the direction opposite to the good conductor plate can be expected.
In addition, by bending the good conductor plate so that the direction of the magnetic field lines of the fluctuating magnetic field radiated from the feeding coil is reflected in a certain direction, or by making a case of a good conductor having at least one surface open. Improvement of the gain or directivity of the feeding coil can be expected.

The electromotive force induced in the power receiving coil depends on the voltage of the AC power source supplied to the power feeding coil, depends on the inductive reactance of the power feeding coil, and depends on the distance between the power feeding coil and the power receiving coil. , Depends on the ratio of the number of turns of the power receiving coil and the number of turns of the power feeding coil, depends on the area of the power receiving coil, depends on the relative permeability of the magnetic body of the power receiving coil, or depends on a combination thereof Therefore, by changing the combination of these parameters, the induced electromotive force can be estimated and optimized.
In addition, the feeding coil and the receiving coil have a thickness in which the short sides of the flat rectangular conductor are stacked with a plurality of insulating thin plate conductors within a range in which the resistance value does not become excessive due to the skin effect, or the rectangular conductor and the insulator are sandwiched. By overlapping in the shape, the increase in loss due to the skin effect can be reduced.

Further, the feeding coil can be divided into a plurality of sections, intersected in a plurality of sections, or distance information can be generated by a combination thereof.

In addition, since a large exciting current always flows through the power supply coil, an inrush current that flows through the AC power supply 31 when the AC power supply 31 is started up by connecting a phase adjusting unit connected in parallel with the power supply coil to a reactor 32b and a capacitor 32a. And the power factor is improved by the phase adjusting means 34 connected in series with the power supply coil, and when there is no power supply request from the power receiving means, the current supply to the power supply coil is cut off, or the power supply coil It is necessary to take measures such as lowering the supply voltage.
