(Embodiment 1)
FIG. 1 is a configuration diagram of a power transmission / distribution system according to a first embodiment of the present invention, in which 101 is a power transmission / distribution system, 11 is a power feeding coil, 41 is a power receiving coil, 21a and 21b are input terminals of the power feeding coil, 51a, 51b is an output terminal of the receiving coil, 31 is an AC power supply, 32a and 32b are phase adjusting means connected in parallel, 33 is power distribution means, 34 is phase adjusting means connected in series, 61 is power storage means, and 62 is rectification Means 63, power receiving means 64, phase adjusting means 64 connected in series, and 100 an interval between the feeding coil and the receiving coil.

Here, the power feeding coil 11 and the power receiving coil 41 are air-centered, are provided in the periphery of a magnetic body having a high magnetic flux density in an unsaturated state, and the coil and the magnetic body are not in direct contact with each other. It is assumed that they are provided at an interval or a combination thereof, and are opposed to each other in the horizontal direction with an interval 100 therebetween.
Further, each coil has a structure in which the magnetic flux density is not saturated by the AC power source to be driven, and has a structure in which the magnetic flux density is not saturated, or an air core that can drive a large current.
The power feeding coil 11, the phase adjusting means 32a and 32b, the phase adjusting means 34, and the AC power supply 31 constitute a constant voltage series-parallel resonance type inverter.

  Further, the inductive reactance of the feeding coil 11, the capacitive reactance of the phase adjusting units 32a and 32b connected in parallel, and the capacitive reactance of stray capacitance existing around the feeding coil are in a non-resonant state. 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 31 is reduced, the emission 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 is converted and output, converted to DC voltage by the rectifying means 62 and output, output to the storage means, or a combination of these is output as a large current power source, and as a whole power transmission and distribution Make up a stem.

  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.

Further, in the case of a circular coil in which the radius of the feeding coil is a1, the area is S1, the number of turns is N1, and the relative magnetic permeability of the magnetic material is μe1, it is generated at a position Z (m) from the point of the feeding coil 11b. The magnetic flux density B is such that the feeding coil and the receiving coil face each other in the horizontal direction, and the relative distance is expressed by D = (a1 ^ 2 + Z ^ 2) ^ (1/2).
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)
In addition, the radiant magnetic flux density is similarly required for single lines, multiple lines, two parallel lines, and the like.

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 established, there is a problem that the load power factor of the current Iout (A) flowing through the power storage unit is reduced and the 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 with respect to the AC power supply is high and the power supply efficiency is good.However, when the relationship ωL2 <R is not satisfied, the reactance 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.

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 the EV, 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, thereby It is possible to reduce the eddy current loss that occurs in the existing object or EV body and to increase the radiation of the variable magnetic field in the opposite direction to the good conductor plate.

Here, either or both of the feeding coil 11 and the receiving coil 41 are air-centered, non-saturated, non-resonant, non-resonant near the resonance, and horizontally. They are opposed to each other or a combination thereof, and a large excitation current can be driven to radiate a high-output fluctuating magnetic field on the feeding coil side, so that a high-output electromotive force can be induced from the receiving coil.
In addition, a single flat line, a double line, two parallel lines, a rectangular loop coil, a rectangular helical coil, a rectangular spiral coil, or a flat rectangular coil formed by a combination thereof is grounded in the horizontal direction for the feeding coil 11, Installed along the driving lane, installed in the power supply service area, configured a seamless and long power supply coil, or combined with these, the high power is not Enables contact power supply.
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.

  Further, the feeding coil and / or the receiving coil are configured by a flat conductor, and the flat conductor and a high dielectric constant insulator are stacked in a sandwich shape to form a flatwise winding as shown in FIG. It is impregnated with an insulating material to be waterproofed, the flat conductor is wound around a drum in a horizontal direction, the flat conductor is installed in a horizontal direction with respect to the ground, and distributed capacitance or stray capacitance is added to the coil. Thus, the burden on the phase adjusting means can be reduced, or the combination can be made economical.

It is possible to suppress the signal, to suppress the electromagnetic wave signal re-radiated from the power receiving coil, and to suppress the emission or re-radiation of the displacement current in water or sea water, so that the loss due to the eddy current loss can be reduced. Because it can be suppressed, a large fluctuating magnetic field is radiated from the feeding coil to the outside with high efficiency in the seawater. It is possible to induce a large electromotive force at a high efficiency.

Further, the power supply coil is installed horizontally on the road surface as two flat parallel lines, the power reception coil is installed as a rectangular coil on the moving body facing the power supply coil, and the voltage of the AC power source that drives the power supply coil Is Ein * Sin (ωt), the electromotive force Eout induced in the receiving coil is
Eout = -dΦ / dt = [((Ein / Ly1) * N2 * S2) / (2 ^ 0.5 * D1 * ACOSH (Lx1 / w1))] Sin (ωt) −− (5)

Further, according to the equation (5), the electromotive force increases in proportion to (1) the number of windings N2 and the area S2 of the receiving coil, (2) increases in inverse proportion to the relative distance D1, and (3 ) The width w1 of the parallel two lines increases as it approaches Lx1.

Further, when 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, the current flows to the power storage means even if the power receiving coil is in a non-resonant state. The current Iout (A) is
Iout = Eout / (R + jωL2) ≒ Eout / (R) = [(((Ein / (Ly1 * R)) * N2 * S2) / (2 ^ 0.5 * D1 * ACOSH (Lx1 / w1))] Sin ( ωt) --- (6)
Thus, an effective current flows through the power storage means, and non-contact power feeding is possible in the air and sea water.
Further, when the relationship ωL2 <R is not established, a phase adjusting unit having a reactance of (1 / ωC2) is connected in series to the power receiving coil, and (1 / (ω ^ 2 * L2 * C2)) ≈1 When the non-resonance is close to the resonance state, a charging current having the same phase as the electromotive force flows through the power storage means.

The load Q value is 50 or less, the voltage fluctuation rate under load is 50% or less, and the excitation current flowing through the power supply coil 11 is circulated to reduce the burden on the AC power supply 31, whereby the AC power supply The power supply coil 11 is short-circuited with respect to the second harmonic, and a parallel resonance circuit or trap that resonates with odd harmonics of the AC power 31 is connected in series with the power supply coil 11 to be radiated from the power supply coil 11. It is assumed that the radiation of the electromagnetic wave signal is suppressed, the variable magnetic field is efficiently radiated to the outside, or a combination thereof.

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. A resonance state or a non-resonance state close to the resonance state, a load Q value of 50 or less, a load voltage fluctuation rate of 50% or less, and suppressing re-radiation of an electromagnetic wave signal, It is assumed that an electromotive force is efficiently induced from the radiated variable magnetic field and effective power is supplied to the power storage means 61.

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 is Iin = (Ein / ωL1) Cos (ωt), which is a large excitation current. Therefore, phase adjusting means 32a and 32b are connected in parallel to the input terminal side of the feeding coil 11, and the excitation current is circulated in a resonant state or a non-resonant state close to the resonant state with respect to the fundamental wave of the AC power supply.

Non-contact power feeding and magnetic wave communication are possible in substances that are large compared to propagation loss in the atmosphere, in fresh water or seawater with a salinity of 0% to 10%, or in a combination thereof. .

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. A non-resonant state, a resonance state or a non-resonance state close to the resonance state, the load Q value (ωL2 / R) of the power receiving coil is 50 or less, and the frequency of the AC power source that drives the resonance frequency of the power receiving coil It is in a lower state, the voltage fluctuation rate under load is 50% or less, or a combination of these suppresses the electromagnetic wave signal re-radiated from the power receiving coil, thereby enabling non-contact power feeding in seawater Become.

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 with respect to the AC power supply is high and the power supply efficiency is good.However, when the relationship ωL2 <R is not satisfied, the reactance is (1 / It is necessary to take measures by connecting the phase adjusting means 34 of ωC1) in series.

The resonance state or the non-resonance state close to the resonance state, the output impedance of the AC power supply is made lower than the load impedance, the reactance of the feeding coil is reduced, and the load Q value (ωL1 / R) of the feeding coil is If the resonance frequency of the power supply coil is lower than the frequency of the AC power supply to be driven, the voltage fluctuation rate during load is 50% or less, or a combination thereof, the power supply coil radiates from the power supply coil. Therefore, non-contact power feeding in seawater is possible.
In addition, even when the reactance of the power feeding coil and / or the power receiving coil is larger than the internal resistance R (Ω) of the power storage means, the voltage of the power storage means is set high so that the power distribution coil and / or the power receiving coil It has been confirmed that the influence of the load Q can be reduced.

Here, both or any of the feeding coil 11 and the receiving coil 41 are air-centered, non-saturated, non-resonant, and in a non-resonant state close to a resonance state or a resonance state, Opposite in the horizontal direction, or a combination of these, it is possible to drive a large excitation current on the feeding coil side to radiate a high-output fluctuating magnetic field and induce a high-output electromotive force from the receiving coil .

Further, when 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, the current flows to the power storage means even if the power receiving coil is in a non-resonant state. The current Iout (A) is
Iout = Eout / (R + jωL2) ≒ Eout / (R) = [(((Ein / (Ly1 * R)) * N2 * S2) / (2 ^ 0.5 * D1 * ACOSH (Lx1 / w1))] Sin ( ωt) --- (6)
Thus, an effective current flows through the power storage means, and non-contact power feeding is possible in the air and sea water.
