Background of invention
The present invention relates to a kind of multi-functional energy conditioner, it has on the structure center conduction utmost point of sharing, and can cooperatively interact with charged and paired above-mentioned differential electrode simultaneously according to anti-phase or charging modes along with differential electrode operation respect to one another.
The current main electronic equipment of producing comprises small-sized active parts and the circuit that is used for carrying out high-speed functions, and utilizes high speed electric interconnection delivering power and data between critical piece.These parts are easy to parasitic by appearing at the electric energy of serving or utilize electromagnetic interference in the circuit of these systems and voltage transient to be produced.Voltage transient is understood major injury or is destroyed this miniature electronic parts, or by contact electronic equipment is lost efficacy, and often needs expensive maintenance and/or expensive replacing.
EMI, the electrical Interference of the parasitic form of RFI and electric capacity and inductance can be from producing and sense circuit and the parts such as radio broadcasting antenna or other electromagnetic wave generator.Circuit also can produce EMI, thereby just need shield EMI.On cable and circuit board traces, tend to produce difference and common mode current.In many cases, the effect of the field of these conductor emissions just likes antenna.In order to prevent to interfere with other circuit, be necessary to control these conduction/radiation to the hazardous noise sensitivity.The equipment of work also can produce other interference source to the which couple energy, may produce tangible interference.In order to satisfy the requirement of international radiation and/or sensitiveness, must eliminate this interference.
Thunder and lightning can induce transient voltage on power line, produce very high current potential in the short time at the utmost point.Similarly, electromagnetic pulse (EMP) also can produce big due to voltage spikes, produces the fast rise time pulse in a wide frequency ranges, and is harmful to most of electronic devices.The big voltage transient in other source and earthing potential change the ground loop interference that causes also can destroy electric power system.Existing safeguard measure can't provide sufficient protection in single integrated encapsulation.Various filters and surge restraint circuit structure have been designed according to prior art.In No. 5,142,430, the U.S. Pat of this paper institute reference, the details of various inventions in the prior art has been described.
' 430 patents itself relate to power line filter and surge protection circuit parts and circuit thereof, are used for constituting a protection device into electric equipment.These circuit blocks comprise wafer or the plate-like material that has such as desired electrical characteristics such as variable resistor or capacitance characteristics.On the surface of dish, have electrode pattern and isolation strip, also be furnished with the hole that forms in inside, so that with circuit these parts are connected on the conductor in the system in a kind of simple and efficient mode.Electrode pattern complements each other to form public electrode, and material is clipped in the middle.' 430 patents mainly are the filtering that is used for paired transmission line.Electric power system can only be born the short sawn timber life cycle in year surplus in the of ten.The system that the first two years has just built up for same category of device the 3rd or the 4th generation product just out-of-date.Therefore, construct the parts and the circuit upgrading in time of these systems.
The performance of computer or other electronic system often is subjected to the restriction of the slowest active element of its speed.As of late, still controlling the specific function and the calculating of overall system such as these elements such as microprocessor and memory members.Yet, along with microprocessor, the latest development of memory member and data thereof, main problem is to be that the user provides stronger disposal ability and speed with the unit cost that reduces.Therefore, engineering problem how to regulate the energy that flows to electric device has constituted cost and technical difficulty.Played for the year ends 2000 from the 1980's, the exemplary operation frequency of main flow microprocessor has improved about 240 times from 5MHz (per second 1,000,000 times), has reached about 1200MHz+.Current processor speed has been caught up with the development and the application of ultrahigh speed RAM structure.These breakthroughs have made total system speed surpass the 1GHz high point.In the same period, the passive component technology does not but have much progress, only slightly changes on composition and performance.Passive component progress in design mainly has influence on part dimension and dwindles, the slight modifications of discreet component electrode level, and the discovery of novel medium, and be the technological improvement of the shortening parts production time manufacturing industry being carried out.
In the past, the passive component engineer solves design problem by the number of components that increases in the circuit.This settling mode often will increase inductance and resistance, is used electric capacity and realizes filtering and decoupling.
Yet what can not be ignored is that single passive parts and many network of passive components all exist a kind of main restriction on the circuit regulating power.This restriction is an obstacle to the technological progress and the growth of computer industry, and has stayed last leftover problem for+GHz speed system.This restriction of High Speed System performance embodied a concentrated reflection of be processor, memory technology and those systems that are positioned at specific electronic system outside provide and regulate the formed restriction of supportive passive component of energy and data-signal.
According to professional OEM to Gao Suchuliqi ﹠amp; The new product of new-type memory pool is applied the historical data record of the recent system failure that is occurred, and improves the speed of microprocessor and memory pool and has brought another problem.Current passive component technology is to cause the root of many faults and delay.Its reason is that the operating frequency of single passive parts has one 5 physical cord to 250MHz to regulate limit usually.The high frequency of many parts all need be such as discrete L-C-R, and L-C, the passive component of R-C network make up shaping or control to offer the energy of system load.Frequency band more than 200MHz, the discrete L-C-R of prior art, L-C, R-C network begin the characteristic that transmission line occurs even be similar to the microwave feature, and network design original intention desired lumped capacitance, resistance or inductance can not be provided.Microprocessor, clock, this performance difference between power supply bus and accumulator system and the supportive passive component thereof can cause the system failure.

The explanation of most preferred embodiment
Use electronic equipment in the daily life more and more, and the radiation of electromagnetic interference (EMI) amount and generation to Electromagnetic Compatibility new requirement has been proposed.These new regulations encapsulate PCB at distinct electronic apparatuses but for example be not limited only to specific I C (integrated circuit), DSP, microprocessor controller, switch mode power, network, connector, avionic device, radio telephone, consumer-elcetronics devices, instrument, military igniter and control appliance or the like.The present invention be directed to a kind of physique that is used for electronic unit, it can also provide EMI to suppress in an integrated component or assembly simultaneously effectively; Circuit is regulated, broadband I/O line filtering, EMI decoupling noise-cut and surge protection.
Propagate the electromagnetic interference energy demand electric field and magnetic field are arranged.Electric field is coupled in the circuit by the differential voltage between 2 or the multiple spot.The electric field that changes in the space can produce magnetic field.Any time dependent magnetic flux all can produce electric field.Therefore, time dependent pure electric field or pure magnetic field can not exist independently of one another.Passive component of the present invention is constructed and can be used for regulating or reducing these two kinds of energy field that are present in the electrical system.The present invention does not need to manufacture the field of one type of special adjusting, but can increase or use the inhomogeneity material and be built into an embodiment, can be used for the adjusting from a kind of energy field to another kind of energy field.
The accumulation of electric charge can produce electric field, just can observe this accumulation on two borders between a conductor and another non-conductor.According to the Gauss law, the boundary condition state can form conduction encirclement or the semi-surrounding that is called as Faraday box or Faraday box structure, the part is comprised or is positioned at the transport element generation electrostatic screen effect of this shielding structure inside.At the boundary vicinity of this shielding construction, most of electric charge and the parasitic inboard that is maintained at the shielding border.So just can repel and be present in outside most of electric charge and the parasitism of this boxlike shielding, avoid the inner field that produces remaining on the adverse effect of the conductor in the box.The electric field and the magnetic field of coupling have the character of propagating forward with the light velocity, unless the energy field of propagating along conducting path has run into the impedance or the resistance that can hinder the energy field propagation along above-mentioned conducting path.
This impedance or resistance provide the notion of " skin effect ", and it has indicated the effectiveness of magnetic screen and the relation of the material that constitutes conducting path.
As mentioned above, the electromagnetic interference of propagation may be respectively from the product in electric field and magnetic field.The emphasis point of prior art up to now is with DC energy or electric current filtering EMI on the circuit that transmits high-frequency noise or the energy conductor.Yet the present invention can be with the DC that propagates along conducting path that exists in electrical system or the testing equipment, and AC and AC/DC hybrid energy are regulated energy.This comprises and utilizes the present invention to regulate energy in being present in the system that same electrical system platform inside comprises comprising of multiple circuit propagation characteristic of many inhomogeneity energy transmissions form.Radiation problem may be mainly since difference and two kinds of conduction currents of common mode energy cause.The field that is produced by these electric currents can produce multiple EMI emission.Differential pattern (DM) electric current is meant at lead, the electric current that flows in the circular path of circuit board traces and other conductors.With these current related electric fields be to send the loop that limits from conductor.
The single or multiple passive components that the higher operational frequency requirement user of most of circuit adopts combination are such as inductance, and electric capacity or resistance form L-C-R, and L-C and R-C discreet component network are controlled the energy that offers system load.Yet, the discrete L-C-R of prior art, L-C, the frequency of R-C component network more than 200MHz just begins to occur the characteristic of transmission line, or even the characteristic of microwave can occur being similar on higher frequency.The parasitism of minimizing can appear not being suppressed or not having like this, or be used for deterioration to occur from the syndeton that outer set is combined between all discrete elements of above-mentioned network, speed reduces, or tangible decay can occur along the energy that circuit is propagated on the wide region operating frequency.This has tangible harm for the large-scale circuit that above-mentioned network connected.The original design by network provides concentrated electric capacity, resistance or inductance, the high frequency capacitance parasitism that is distributed on the internal electrode within the prior art component network may be the energy attenuation of circuit, one of multiple reason that weak or performance reduces.Above-mentioned substandard performance loss for example still is not limited only to loss of data, line delay or the like, and can bring tangible circuit malfunction problem.
The difference of common mode and differential mode energy is that they propagate in different circuit paths.Common-mode noise may be caused by electrostatic induction, reason is that conducting path and electric capacity on every side equate, and on two lines, form same noise voltage, and/or cause by the magnetic field of electromagnetic induction, magnetic field is from the conducting path of paired link, or many conducting paths are having essentially identical noise voltage on the conducting path in pairs simultaneously, and above-mentioned noise energy can be propagated on the superficies of conductor.Differential noise is caused by the Voltage unbalance of alive circuit inside often, and interference can make the current potential of signal transmission path one side change with respect to an other side.In order to reduce, the noise that reduces or suppress to be harmful to, the present invention has utilized and has been based upon an inner low impedance path, and the present invention is the part conduction ground connection with above-mentioned harmful energy, and/or (according to the present invention) delivers on an exterior conductive zone or the path.The part in this path can be positioned at inside of the present invention, and comprises public conductive plate part and or the structure of being made up of them.The exterior conductive zone of public conductive plate or structure and the extension that produced thereof can make energy propagate into one along these conductive shields path element bigger to be positioned at outside conductive area, in path or the system earth, it mainly is positioned at and is in inner public conductive plate zone or as the outside of the shielding structure of part of the present invention.The possible outside in the path from a plurality of public conducting paths of the present invention to multilayer embodiment of the present invention outside connects and/or annex can be realized with multiple possible industrialization means commonly known in the art.This type of conduction annex of shielding structure from public conductive plate or annex to conduction is that the common board unit construction by these joints forms, and in most of the cases be connected to the difference conducting path, and be connected on the multi-functional energy conditioner, comprising power supply, multi-functional energy conditioner provides the overall noise current loop area of a shortening in the alive circuit of conducting path and load.In the present invention is connected to the circuit with energy loop and energising the time can produce at least two above-mentioned energy loops, these two loops are in parallel, but be in the relative both sides of public conductive plate in center or path, and above-mentioned loop phase phasic difference 180 degree to each other, like this, opposite energy will offset, and can reduce or suppress noise.A kind of charged structure that comprises multi-functional energy conditioner in bigger alive circuit inside can also provide multiple possible conducting path in multi-functional energy conditioner inside, can be used for transmitting from the energy to the load part energy.The public shielding conductive plate of being made up of panel element and/or the part of shielding structure are being used for from the energy or during from the load Propagation of Energy, return path as the energy, between the each several part of paired difference conducting path, have independently short distance or loop area, and, when public conducting structure or public conductive plate were used as the energy transmission part, this return path can be used as one or many return paths that return its source.Be connected to separately external conductor or the path on the time, a part of loop area is positioned at the inside of multi-functional energy conditioner, provides distance between difference conductive plate or path and public conductive plate or the path by intervenient dielectric material.The part energy that circuit is propagated can be along the internal migration of multi-functional energy conditioner, and the part energy from the energy to the load migration is opposite to the migratory direction of that part of energy of energy migration from load with the circuit inside that multi-functional energy conditioner is installed.As mentioned above, the energy of phase anti-spread is separated by public conductive shields path, center, the latter also is comprised in the Faraday boxlike shielding construction, in all multi-functional energy conditioner inside all across medium, and can regulate above-mentioned energy simultaneously with respect to the static characteristic of Faraday boxlike shielding construction, the main magnetic field of in the short path of isolating, repealing by implication as mentioned above.The public conducting electrode of marshalling or path are from physically having shielded above-mentioned paired differential power conductive plate or most of area in path to each other, and make closely approaching above-mentioned difference conducting path energising the time separated by public shielding path all the time closely on play opposite effect, coact with complementation or coordinated mode, provide effective energy adjustment in multi-functional energy conditioner inside.In adjuster of the present invention, part foregoing circuit energy can be propagated along the difference conductor between the distinct public conductive plate of two parts zone on sometime, the difference conductor is separated by medium from public conductive plate zone separately, and this part energy is in the part of the above-mentioned energy of multi-functional energy conditioner internal communication in the work of alive circuit.
Referring to Fig. 1, represented a decomposition diagram of the physique of multi-functional energy conditioner 10 among the figure.Multi-functional energy conditioner 10 is made of a plurality of public conductive plates 14, has two battery lead plate 16A and 16B at least, and each battery lead plate 16 is sandwiched between two public conductive plates 14.Insulated hole 18 or coupling aperture 20 by a plurality of public conductive plates 14 and battery lead plate 16A and 16B are provided with pair of conductors 12a and 12b at least, allow the also selected coupling aperture 20 that is connected to battery lead plate 16A and 16B of conductor 12a and 12b.The whole public conductive plate 14 that for example is made of with metal in most preferred embodiment or different embodiment conductive material can be to be deposited on one according to the conductive material that is similar on the medium lamination (not shown) that the technology of making chip capacity makes.By each common ground conductive plate 14 at least one pair of insulated hole 18 is set, allows conductor 12 pass through, keep the electric insulation between public conductive plate 14 and the conductor 12 simultaneously again.A plurality of public conductive plates 14 can select to install the fastener hole of arranging according to predetermined cooperation position 22, allow a plurality of conductive plates 14 for example be that screw rod and screw closely are coupled by the standard fastener to each other, or (not shown) can be with being similar to technology manufacturing of making chip capacity or the like and the elastic piece structure that is bonded into standard in the embodiment of change.Fastener hole 22 can also be used to multi-functional energy conditioner 10 is fixed on another non-conduction or the conducting surface, for example is to be fixed on the shell or chassis that is used with electronic device multi-functional energy conditioner 10.

Each circuit is that battery lead plate 16B by correspondence provides to the ground capacity 32 second required parallel-plates.See figures.1.and.2 and just can find out the relation of capacitor board.With material 28 center common ground conductive plate 14 is isolated with each battery lead plate 16A or 16B with electrical characteristic, the result has just formed a capacitance network, it has a common mode shunt capacitance 30 of extending between conductor 12a and 12b, and is coupled to circuit on the bigger exterior conductive zone 34 to ground connection decoupling capacitor 32 from each conductor 12a and 12b.
Below also want the bigger exterior conductive zone 34 of specific explanations, but from supposing that instinctively it and the earth or circuit ground are equivalent.Bigger exterior conductive zone 34 can be coupled with center and additional public conductive plate 14, form the public conductive plate 14 that links to each other on one or more circuit with above-mentioned central plate 14 combinations, and can be coupled to circuit or greatly by means of the conventional means of prior art, for example be welding or the screw that insertion fastener hole 22 is installed, be coupled to then on the shell or hot chassis of electric equipment.Although the effect of this multi-functional energy conditioner 10 is equivalent to be coupled to the intrinsic ground connection 34 of the earth or circuit ground, an advantage of the physique of this multi-functional energy conditioner 10 is to depend on required energy condition, does not need the connection of actual ground connection in some concrete application.
Referring to Fig. 1, supplementary features of multi-functional energy conditioner 10 have been demonstrated among the figure respectively with clockwise and counterclockwise flux field 24 and 26.The direction of each flux field is to adopt Ampere's law and determine and draw with right-hand rule.For this reason the parallel placement of the thumb of two hands and sensing can the be flowed through sense of current of conductor 12a or 12b is shown in arrow of each end of conductor among the figure.If thumb and electric current point to same direction, the crooked direction of other fingers of staff is just represented the direction of rotation of flux field.Because the position of conductor 12a and 12b is adjacent one another are, and can represent the current loop of common one or more in many I/O and the data circuit structure, the electric current that enters and leave multi-functional energy conditioner 10 is reciprocal, the opposite flux field 18 that generation can mutually offset in closely, 20,24,26, and the inductance that is applied on the device is very little.Along with the increase of new-type facility switching speed and pulse rise time fast, can produce unacceptable due to voltage spikes, have only low inductance surge device and network just can deal with, therefore, low inductance is an advantage of new-type I/O and high speed data lines.Compare with the discreet component of available technology adopting combination, adopt multi-functional energy conditioner 10 that tangible effect is also arranged on the meaning of labour intensive, for manufacturing industry provides a kind of convenient and low cost method.Because just only need connect at arbitrary end of conductor 12 to provide a circuit to line capacitance for circuit, its value approximately is 1/2 of a capacitance that each circuit of forming in inside in the present embodiment is recorded to ground capacity, so just for the user provides flexibility, and when utilizing the present invention to make bigger electrical system, can also save time and the space.
The comparison that the circuit that Fig. 3 A represents the multi-functional energy conditioner shown in Figure 1A 10 is measured .20 μ F is done to the response of through hole capacitor 50 (not shown) of the roughly the same prior art of the measured common mode insertion loss of line capacitance and physical size and diameter.It is different to the performance of line capacitance with multi-functional energy conditioner 10 performance by contrast with .20 μ F capacitance that curve display goes out circuit that the prior art capacitor 50 with .47 μ F capacitance constitutes.If these two multi-functional energy conditioners 10 and 50 all are connected to the exterior conductive zone, compare the insertion loss reading (only limiting to testing equipment) that multi-functional energy conditioner 10 demonstrates obviously and difference is very big in up to the 1200MHz frequency range with capacitor 50.Fig. 3 B represents the comparison that the response of through hole capacitor 50 (not shown) of prior art identical among differential mode that the same multi-functional energy conditioner 10 that Fig. 3 A adopts is recorded and Fig. 3 A is done.If these two multi-functional energy conditioners 10 and prior art capacitor 50 all are connected to the exterior conductive zone, the insertion loss (only limiting to testing equipment) that multi-functional energy conditioner 10 demonstrates in up to the 1200MHz frequency range obviously and difference is very big.
Curve 3B represents that constituting circuit with .47 μ F capacitance is different to the reading of the prior art capacitor 50 of ground capacity with multi-functional energy conditioner 10, the circuit of the latter's adjuster 10 1 lateral capacitances is .40 μ F to the ground capacity value, and approximately is two times to line capacitance value .20 μ F of the circuit that recorded from multi-functional energy conditioner 10 before the test of Fig. 3 A.

Fig. 5 B represents to have four difference and common-mode filter pin to the difference of structure and a schematic diagram of many conductors of common mode multi-functional energy conditioner 110.Extend through each the horizontal line of electrode is represented public conductive plate electrode 112A, 112B and 112C surround insulating material 112a with these lines.Insulating material 112a is electrically coupled to public conductive plate electrode 112A, 112B and 112C and side conducting terminal material 112D, the conductive grid that provides zone that a quilt do not have electric conducting material and battery lead plate 118a further to separate to 118h, thus each battery lead plate 118a is separated with conductive grid each other to 118h.Corresponding electrode 118a to 118h be positioned at fid flitch 116A and 116B above, be in the above and below of center common ground conductive plate 112, and constitute circuit and arrive ground connection common mode decoupling capacitor.Each battery lead plate 118a is to 118h, public conductive plate electrode 112A, and 112B and 112C and fid flitch 116A and 116B are spaced from each other by dielectric material 122.When multi-functional energy conditioner 110 by for example being coupling aperture 120 among battery lead plate 118a and the 118c when being connected on the paired conductor, multi-functional energy conditioner 110 has just formed a common mode and differential mode filter.
Referring to Fig. 4, the multi-functional energy conditioner of representing among the figure 110 not only has center public conductive plate electrode 112B and also has public conductive plate electrode 112A in the outside and 112C.Described as reference Fig. 1 and 1A, if these outside public conductive plates and public conducting electrode 112A and 112C are bonded with each other together, and provide an exterior conductive path or a zone that obviously increases for multi-functional energy conditioner 110 together with each conductive plate 14 of each center of the present invention or center each electrode 112B and an exterior conductive zone (not shown), simultaneously can suppress and/or reduce again and/or the electromagnetic emission of decay paired radiation of conductors and conduction, and between the above-mentioned conductive plate of Fig. 1 and 1A or other embodiments of the invention and electrode, provide shielding, provide a bigger surface area to disperse and/or absorb overvoltage, surge and other transition noises, and when energising, play the effect that a Faraday boxlike shields effectively.A popular tendency of all new-type electronic equipments is exactly the continuous miniaturization of equipment and the electronic unit that constitutes this equipment.Critical component capacitor in the multi-functional energy conditioner structure is no exception, and its size has narrowed down to the degree that can be shaped and embed in the integrated circuit gradually in silicon chip, have only with microscope and just can see.Very popular a kind of midget capacitor is a chip capacitor, and it is more much smaller than the through hole or the lead capacitance device of standard.Chip capacitor adopts surface mounting technology to realize physics and electric being connected with the conductor on the circuit board with track.The multifunctionality structure of multi-functional energy conditioner of the present invention can expand to surface mounting technology as shown in Figure 6.Fig. 6 A represents a kind of mounted on surface multi-functional energy conditioner 400, and its internal structure is shown in Fig. 6 B.Referring to Fig. 6 B, public conductive plate 412 is sandwiched between the first difference plate 410 and the second difference plate 414.Public conductive plate 412 and the first and second difference plates 410 and 414 all are to be made of the material 430 with the predetermined electrical characteristic that depends on that material is selected separately.In all embodiment of the present invention, but expect that operational various material for example is not limited only to dielectric material, the MOV material, Ferrite Material is such as Mylar and the new particular matter film of sintering polycrystalline material or the like for example.
The first difference plate 410 comprises the electrode 416 that is coupled on material 430 end faces, stays isolation strip 418 and surrounds its outer periphery along three limits in four limits of the first difference plate 410.Isolation strip 418 is those parts that do not covered by electrode 416 as yet along material 430 edges.The second difference plate 414 and the first difference plate 410 are roughly the same, and unique difference is the physical arrangement mode difference with respect to the first difference plate 410.The second difference plate 414 comprises the electrode 426 that is coupled on material 430 end faces, stays isolation strip 428 and surrounds its outer periphery along three limits in four limits of the second difference plate 414.Main points about the first and second difference plates 410 and 414 mutual physical arrangement are that each plate is not arranged to differ each other 180 degree by isolation strip 418 and 428 those sides of surrounding.In Figure 19, have further explanation about the first and second difference plates 410 and 414 main points with respect to the physical arrangement of public conductive plate 412, each differential electrode 412 and 410 conduction surface are by the shielding each other physically of the public conducting electrode 412 in intervenient center, each differential electrode 410 and 414 border or periphery are inserted into to a certain degree with respect to the border or the periphery of public conducting electrode 412, allow the remaining zone of public conductive plate or the zone that is covered provides one than the bigger size of the corresponding size of difference conductive plate of clamping above-mentioned public conductive plate 412 for public conductive plate.The overlapping scope of the difference plate that equates with respect to public conducting electrode 412 with respect to size roughly is inserted into such degree,
The time be enough to capture the parasitic animal and plant of attempting to escape or enter in energising, prevent performance degradation by the occupied zone of differential electrode.Difference conductive plate 410 and 414 is inserted into this point with respect to one group of bigger common board of clamping a difference plate and can strengthens electrostatic screen under electriferous state.This arrangement allows a conductor circuit is coupled to arbitrary single plate 410 or 414, but does not need the coupling with both sides, so just can still be formed with phase difference between the difference conductor of position opposite in pairs but complementary energy adjustment.
Below to further explain the structure of mounted on surface multi-functional energy conditioner 400 with reference to Fig. 6 A.When common board 412 and the first and second difference plates 410 and 414 are sandwiched in a time-out according to Fig. 6 B and layout shown in Figure 19, make two additional public conductive plates location, clamp difference plate 410 and 414, the latter clamps public conductive plate 412 again.In the present embodiment, the composition material of plate 412B and 412A, size is substantially the same, and roughly is and is arranged in parallel, and allows separately band and electrode rim be within the above-mentioned center conductive plate 412.Must there be a device that conductor is coupled to differential electrode 416 and 426.Conductor dbus is crossed the first difference conduction band 404 and the second difference conduction band 406 that are positioned at isolation strip 408 isolation of being with between 402,404 and 406 and is coupled to mounted on surface multi-functional energy conditioner 400.Public conduction band 402 and isolation strip 408 can be around Subject Extension 360 degree of multi-functional energy conditioner 400, provide isolation at all four sides, but, because public conductive plate 412,412A and 412B have surrounded above-mentioned differential electrode 414 and 410 with almost completely shielding, replace being with 402 if be similar to form commonly used in the conducting terminal structure (not shown) of terminal band 84 shown in Figure 14 or the prior art, just can dwindle the size of public conductive plate 402 even its cancellation with shape and function class.360 degree are not only extended around each position of multi-functional energy conditioner 400 in the first and second difference conduction bands 404 and 406, also extend to and cover end 432 and 434 respectively.
Contrast Fig. 6 A and Fig. 6 B as can be seen with and plate between coupling.The first difference conduction band 404 comprises the end 434 that keeps electric coupling with electrode 416, and the latter does not extend to the isolation strip 418 of the first difference plate, 410 ends.Because the effect of isolation strip 422 and 428, the second difference conduction band 406 are isolated with the common board 412 and the first difference plate 410 respectively on circuit.According to mode similar to the above, comprise that the second difference conduction band 406 of end 432 and the electrode 426 of the second difference plate 414 form electric coupling.Because common board 412, the isolation strip 420 of 412A and 412B and the first difference plate 410,420A, 420B and 418, the effect of 418A and 418B, the second difference conduction band 406 on circuit with the first difference plate 410 and common board 412,412A and 412B isolate.
The electric coupling of public conduction band 402 and common board 412 is that the physical coupling by the side 436 of public conduction band 402 realizes, or changes into along common board 412, and the side of 412A and 412B does not have the public electrode 424 of isolation strip, 424a, 424b.In order to keep public electrode 424,424A, 424B and the first and second difference conduction bands 404 and 406 isolation on circuit is with common board 412,412A, the isolation strip 420 of 412B, 420A, 420B and 422,422A, 422B prevents the end 432 and 434 and public electrode 424 of the first and second difference conduction bands 404 and 406, and any physical coupling takes place for 424A, 424B.
Other embodiment according to difference of the present invention and common mode multi-functional energy conditioner, when electrode was coupled to the first and second difference conduction bands 404 and 406, the first and second difference plates 410 and 414 electrode 416 and 426 effect were that a circuit is to the line differential mode capacitor.Circuit is respectively at each electrode 416 and 426 and public electrode 424,424A, a Faraday boxlike shielding construction that forms between the 424B to the ground connection decoupling capacitor.
Fig. 7 represents another embodiment with the multi-functional energy conditioner of Mylar formula or thin film dielectrics formation.Present embodiment is made of thin film dielectrics, and utilize means commonly known in the art that metallicity and conductivity are provided, constitute a public conductive plate 480 earlier, be the first electrode difference plate 460 then, then being another the public conductive plate 480 and the second electrode difference plate 500, is another public conductive plate 480 subsequently.Each plate all is to constitute with film 472, and itself can be made of many kinds of materials, but for example is not limited only to Mylar, and film 472 is made by complete metalization or with conductor, forms the plate of metallization or conduction with another kind of electric conducting material in a side.Utilize laser to remove a part of metallized electric conducting material (metallization removal) and form isolation barrier according to predetermined pattern.The first difference plate 460 has the isolation barrier 462 and 466 of two laser formings, and the first difference plate 460 is divided into three conductive regions: electrode 464, the electrode 468 of isolation and public electrode 470.The something in common of the second difference plate 500 and the first difference plate 460 is to have two isolation barriers 506 and 504, and the second difference plate 500 is divided into three conductive regions: electrode 510, the electrode 502 of isolation and public electrode 508.The first and second difference plates 460 and 500 isolation barrier 462 and 506 all are U-shapeds, the electrode 464 of formation and the 510 very large tracts of land of surrounding first and second plates 460 and 500.U-shaped isolation barrier 462 and 506 can make electrode 464 and 510 extend to separately end 476 and 514 always.Parts 474 and 512 extend from isolation barrier 462 and 506, and parts 473 and 513 extend from isolation barrier 466 and 504.Parts 474 stretch out with the end on 514 the point is vertical near ends 476 from U-shaped isolation barrier 462 with 506 with 512, and parts 473 vertically on the isolation barrier 466 and 504 respectively stretch out with 513, so that 476 and 514 isolate public electrode 470 and 508 fully from the end.In addition, the first and second difference plates 460 and 480 also have by the electrode 468 and 502 of isolation barrier 466 with 504 isolation that form in relative end.
Public conductive plate 480 comprises isolation barrier 482 and 492, and public conductive plate 480 is divided into three conductive surfaces: public electrode 488, the electrode 484 of isolation and the electrode 494 of isolating.As shown in the figure, isolation barrier 482 parallel with the left and right edge of public conductive plate 480 with 492 and extend in vertical direction with adjoining.Isolation barrier 482 and 492 also comprise stretch out and with isolation barrier 482 parts 496 vertical with 492 vertical cross-section, its position is such, when plate 460,480 and 500 are laminated in a time-out, and they align with the U-shaped isolation barrier 462 of the first and second difference plates 460 and 500 and 506 horizontal component.
Another is characterised in that public conductive plate 480 can select to be used for to AC or DC signal filtering.For the DC signal, the electrode 484 of isolation and 494 only needs very little area in public conductive plate 480.If constitute filter and be used for the AC signal filtering with thin film dielectrics, the electrode 484 of isolation and 494 just needs bigger area, and it is revised isolation barrier 486 and 490 by etching and realizes.Make vertically extending isolation barrier 484 and 494 close with etching, and near public conductive plate 480.In order to realize such modification, stretch out and parts 496 vertical with vertical cross-section longer than the structure that is used for DC.Although any structure can both be to the current filtering of two kinds of forms, larger area isolation barrier 484 and 494 can provide AC filtering performance preferably.
