INSTRUCTIONS: [Technical field to which the invention pertains] The present application is summarized in the extraction of energy from a fluid stream, and more particularly in relation to the toxic weight induced by the fluid flow and utilizing the vibration The unique design of the energy converter and generator that produces electricity. Specific exemplary magnetic field generating members, conductive coil embodiments, and related circuits are set forth. The present application claims the benefit of U.S. Provisional Application Serial No. PCT/A. [Prior Art] A motor produces an AC output that can be converted and raised to a DC output suitable for most applications. In some cases, the generator can produce a low voltage AC output. Low voltage operation can include operation below 12 volts. Low voltage operation may have applications such as operation - small portable radios, - wireless sensor nodes, - bright LEDs, a supercapacitor, a polymer battery or a small NiMh battery. Previous methods for switching low slave power inputs in a generator include the use of a typical bridge rectifier, and then using a separate boost/buck converter to increase the electrical f present in the generator components - dynamic In the case of ranges (eg, their dynamic range due to changing the fluid velocity of a fluid-driven generator), a circuit can operate at (10) input voltage, and the AC wheel-in voltage cannot be controlled by a standard bridge rectifier. Efficiently convert voltages suitable for large-duth applications, or not effectively boosted by a boost/buck converter or converter to voltages suitable for most applications. 131870.doc 200911391 External boost/buck converters can include -矽 components and can be complex and expensive. Previous systems may have used an inductive converter combined with a bridge rectifier. This configuration results in significant power loss in the converter windings and coils, and the volume and cost of such converters for small scale operation. It may be too high to be interested. Previous systems may have tried without a converter, but that could also result in loss of efficiency. Some of these previous attempts may have boosted an AC input to 1 (7-dog multiplication) with an application designed for electronic detection in electronic televisions such as televisions and ionizers. The circuit is related. It is unknown that any kind of multiplier circuit has been associated with a lower voltage (eg 丨 to 12 VDC) application. However, it may be advantageous to develop a variant that is used to operate the circuit in this lower voltage range. The n-cafe is especially suitable for combination with low-cost, low-voltage AC generators. In addition, the new multi-pneumatic dust includes electric dust rectification, load isolation, and harmonics. Process efficiency. _ and low voltage Therefore, there is a need for a device that can provide efficient power generation and transportation to a load. Further need to minimize the complexity and cost of the power supply.

The entire disclosure of the Hai application is incorporated herein by reference. - An exemplary generator may include: one less magnetic field generator, at least one electrical conductor, and at least one flexible film having at least two ends The film can vibrate when it is vented to a fluid. The electrical conductor and the magnetic field can be attached to the film and configured to move with the film. The vibration caused may cause a relative movement between the electrical conductor and the applied magnetic field. The relative movement may cause a change in the intensity of the magnetic field applied to the electrical conductor, and the magnetic field applied to the electrical conductor This change in intensity can induce a current flowing in the conductor. In one aspect, the direction of the magnetic field can be substantially perpendicular to a region enclosed by one or more electrical conductors when the film is not vibrating. In an embodiment, the example generator can further include a support structure to which the fixed end of the film can be attached. One or more magnetic field generators can be attached to one or more surfaces of the film One or more electrical conductors may be disposed on the support structure.

The detailed description and the advantages of the present disclosure will be apparent to those skilled in the <RTIgt; Only example embodiments of the disclosure are disclosed. It should be understood that the present disclosure is capable of other and different embodiments and the various details can be modified in various obvious aspects. Accordingly, the drawings and the description are to be regarded as illustrative rather than limiting. All publications, patents, and patent applications, which are hereby incorporated by reference herein in their entirety herein in the entireties in Requests for proposals, patents or special accounts are incorporated by citation. [Embodiment] In the following description, for the purposes of illustration However, it will be readily apparent to those skilled in the art that the present disclosure may be implemented without such specific details. In the exemplification of the beans, the structures and devices showing the prior teachings are formed in block diagrams in order to avoid unnecessarily obscuring additional embodiments. / -: An exemplary generator may include: a magnetic field generator, an electrical conductor, and a flexible film for converting energy present in a fluid stream (e.g., a gas stream) into vibration or vibration. In the exemplary implementations described herein, the tract film can include at least one magnet generator attached thereto and can have at least two fixed ends. The film can vibrate upon exposure to a fluid stream. As used herein, the term &quot;flex&quot; can mean a film that is capable of deforming into a variety of defined and indeterminate shapes without permanent damage in response to an applied force. ' ° / The at least one magnetic field generator can be constructed as a permanent magnet attached to a thin crucible and assembled to move with the film. For example, one or more of the magnets may be integrated into or onto both sides of the plenum film. Their magnetic field generators can be placed above the corresponding electrical conductors. The material bodies can be constructed as aluminum or copper coils having various _ shapes 131870.doc 10· 200911391. The vibration caused by the fluid flow of the film causes a relative movement between the yttering conductor and the biasing magnetic field of the permanent magnet. This relative movement can cause a change in the intensity of the magnetic field applied to the electrical conductor, and the change in the strength of the magnetic field applied to the electrical (four) can induce a current flowing in the conductor. While using wind or airflow to drive the exemplary generator, the wind can flow perpendicular to the long axis of one of the films, such as when the film has an elongated shape. The flowing fluid can be induced in the tension-bearing thin medium - referred to as aeroelastic flash chatter or simply " &quot; flashing chatter," which is inherently unstable. In some cases, flash chattering can cause various high-energy oscillations. In some cases, 'unstable flashing chattering oscillations can achieve a limit period that provides a stable oscillation mode for the film. In addition, vortex shedding can occur along the edges and surfaces of the film, which in some cases enhances oscillation. Thereby, the vibration of the film causes the magnet to move relative to the coil. A change in the magnetic field can cut the closed area defined by the coil, resulting in the EMF in the coils. Thereby, a current can be generated without physically consuming the diaphragm to a piston or cam to generate electricity. This generator can operate at various wind speeds' including, in some cases, the speed required by most wind turbines based on thirsty wheels. However, the cost of an exemplary generator of the present disclosure can be significantly lower than most other wind-based generators, and no solid grinding parts provide long-term, noise-free, maintenance-free operation. It may not be necessary to use a front bluff body to initiate or maintain oscillation, but a non-streamlined body may be used if desired. In the embodiments described herein, two permanent magnets can be attached to the surface of the film adjacent to the film - 131870.doc -11 - 200911391. As described in the specific variations taught herein, the magnet can be forced into a slightly chevate, substantially untwisted (relative to the major axis of the film) via the flickering effect of the film. The two corresponding conductive coils can be attached to the generally fixed support structure and/or the splint in various orientations relative to the permanent magnet. More or fewer magnets and conductive coils can be used to achieve the desired cost and power efficiency. Figure 1a illustrates an exemplary generator 1 根据 根据 in accordance with the present disclosure. The power generation machine 100 can include a support structure 10, two support structure splints 12 and 14, and two conductive coils 2a, 2b attached to the structure 10 and the splint 12. The generator 100 may also include an elongated film 8 and two permanent magnets 4a, 4b attached to the two surfaces of the film 8. The film anchor sets 6a, 6b can be attached to the vicinity of both ends of the film 8 with a specific separation, and the coils 2a, 2b can be adhered to the surface of the support structure ίο and the splint 12 or to the support structure 1 and the splint 12 Inside, and suspended above the magnets 4a, 4b, respectively. Two wires 18&amp;, can be coupled to coil 2a and two wires 18c, 18d are coupled to the coil holes. The tension applied to the thin web 8 can vary with the flexibility of the film and the physical properties of the support structure 10 and the specific distance between the ends of the support structure relative to the distance between the anchor sets and the crucible. The example generator 100 shown in Figure 1 can operate as follows. The first class _ Lb ' can include running water or gas &amp; present in an artificial ventilation system or in natural wind, for example, which can travel across an elongated and tension-bearing film 8.

That is, in its mode of maximum energy, the generator (10) can This moderate torsional and lifting movement of the intermediate section of film 8 translates into a magnet h on film 8, a reduced torsional oscillation at the location. It should be noted that the higher twisting and smaller linear vibration of the magnets 4a, 4b can be achieved by the almost identical configuration of the generator 1' only requiring a slight change in the tension of the film 8 and the arrangement of the magnets. The oscillation of the maximum energy of the magnet and thus the oscillation of the maximum electrical output capacity can be based on the magnets 4a, 4b and the thin raft on which the magnets are placed, by means of a substantially untwisted, slightly arched path. The oscillation of the movement. This vibrating mode can be illustrated in Figure 115, with small arrows indicating the movement of the magnets 4a, 4b on the film 8. The oscillating of the magnets 4a, 4b can form a magnetic field along the closed regions of the coils 2a, 2b, wherein the magnetic fields are oriented such that an electromotive force (EMF) can be established in the conductive material of the coils 4a, 4b. The clerk can generate a current based on load conditions, internal resistance, impedance, and other factors in a range, that is, electron flow. This basic arrangement of a varying magnetic field relative to a coil of conductive material when applied to any type of generator may follow the physical rules originally described by Mike's Method 131870.doc 200911391. However, the generator! 00 has significant advantages over conventional generators because solid abrasive parts are not required to generate a current. In the exemplary vibrating mode, the magnets 4a, 4b can be substantially in phase with each other. Therefore, the power flowing through the corresponding leads 18a-d can be combined without significant destructive interference. The leads 18a-d can be joined in parallel or in series depending on the voltage and current of the power conditioning circuit t that is desired to be fed to the generator ι.

At its most basic level, the generator (10) can be modeled as a simple machine, which can be transformed into a small movement with a small force and a small movement with a small force. The method of achieving a mechanically superior approach to the end of the film 8 can achieve the force of the magnets 4a, 4b: the high frequency oscillation of the mass 'even in the low velocity fluid flow. ::Because it is higher than originally possible, it can require less magnetic field to be converted into a thunder (for example, a smaller magnet) to effectively transfer the kinetic energy of the fluid flow into electricity. This can be converted into less expensive generator magnets 4a, 4b. The syllabus L / 士屯 田田 will be placed on the soil outside the path of the flowing fluid, and most of the middle section of the film can be unimpeded The flow responds. Referring to the specific construction of the support structure 10 and the splints 12, 14, the layers and phases can be captured between the plates 12, 14 and the support structure 10. The clip 4 can be secured by any number of members by bonding the H" support structure 10, for example or as a mechanical fastener with a bolt of a nut or screw, to 131870, d〇c -14-200911391 and by many other Knowing the options. For the sake of clarity, the screw 16a_16d' can be used in the illustrated generator 1GG to feed into the threaded hole of the support structure (7). Instead, a threadless pass of the entire thickness of the extension structure 1 can be used instead. The holes 'and the corresponding bolts and nuts can be applied. The anchor sets 6a, 6b can be attached to the film 8 via any number of members. In the case of the generator 100, the containers, groups 6a, can be adhered by means of a bonding agent to Film 8. These anchor sets 6a, 讣 can be separated by a predetermined distance, and it is this distance relative to the total length of the support structure 1 that can establish a particular tension of the film 8. Figure 2 depicts Figure la A cross-sectional side view of one of the micro-variations of the generator 1 shown. A support plate 13 and a support structure can be slightly inclined to more effectively capture the slightly arched travel path of the magnets 4a, 4b. Effect can be obtained by π This is achieved by filling each of the coils 2a and one of the holes in the generator shown in 圊la. In some cases, the generator can produce a low voltage AC output that can vary depending on one of the active components of the generator (e.g., a fluid driven diaphragm). For example, a single device of the type described in Figure la operating at a wind speed of 5.5 m/s can generate 3 megawatts of power. This power can reach 1.5 volts RMS at 20 mA rms under matched load conditions. The unit can also operate at lower wind speeds, and in some instances the output of the generator can be as low as 0.6 volts RMS at 2.5 m/s wind speed. The power generated by the generator can be regulated by a power conditioning circuit. For example, the AC output produced by the generator can be converted and raised to a DC output suitable for most applications. The generator can also be isolated from the load, as the generator unit 131870.doc 15 200911391 True moving parts may not have a central overcoming sudden load condition. 1 Regarding the regulation of the power generated by the generator disclosed herein One of the types of power conditioning circuits shown in Figure 3a can be particularly effective in converting the output of the generator to a clean DC. (4) The circuit may include: a plurality of diodes, such as a low leakage Schottky diode; and a plurality of capacitors, such as a low duty button or an electrolytic capacitor. Many different types of diodes and capacitors can be used but the circuit can be substantially unchanged. In the _# embodiment, the circuit can include two diodes and two capacitors. Other quantities of sumps and electric cells (eg, two diodes and three capacitors, or four diodes and four capacitors) can be used to achieve different power regulation characteristics, such as output voltage and Impedance matching. In the circuit diagram, the "coil" can represent a double-coil wind generator. As shown, the output to a load can also be connected to the circuit. When the motor is used in combination, the circuit shown in Figure 3a can achieve voltage rectification, boosting, load isolation, resonant matching, and power storage' and thereby improve the efficiency of the power conditioning process. The power conditioning circuit can be combined to operate simultaneously. The mode may include AC to DC conversion and direct powering from an AC power source without a converter. - Hai Power (5) means that the circuit can provide rectification of a voltage derived from a generator of $ yuan. An embodiment may provide two rectifiers to achieve rectification of the AC AC waveform period. The first half-wave of the AC input may be directed to the capacitor by the one pole. The capacitor may be based on the peak of the input waveform. Charging. On the second half of the -AC input (i.e., during the negative phase), a second diode can direct the flow to a second 131870.doc -16.200911391 capacitor, the second capacitor Based on the wave The peak of the second half of the waveform is used for charging. The capacitors may have a combination of a source having a lower voltage (ie, a battery or a supercapacitor) or a DC output to enable an effective AC. The DC conversion can be performed in the same way that boosting can be achieved. Boosting can involve increasing an AC voltage to a higher dc voltage. A diode and capacitor combination can convert the peak of an AC voltage signal into a DC. The signal 'and thus the voltage can be raised. In one embodiment, the combination can boost the AC RMS voltage of a 2 volt to 5.6 volts DC. The power conditioning circuit can also implement load isolation, thereby Stall caused by a sudden large load connected to the generator winding (sudden increase in the opposing magnetic field due to the current flowing in the generator winding). Self-generator (the oscillation of the type described in the example) The power efficiency of the film generator) can depend on the load conditions. The matched load from one source to the other can act as a load resistor that matches the impedance of the internal source.

The power conditioning circuit provides a means for providing load isolation without the need for an inductive converter and all efficiency losses and associated components and costs. By selecting a capacitor having a reactance that better matches the operating frequency of the frequency of the generator, an inductive converter may not be needed. The capacitors can be selected based on the inductive reactance of the coil and the operating frequency of the generator components, and can be effectively converted to DC via the circuit by preventing a large amount of converted Dc current from flowing back into the circuit in an anti-emf form. The power conditioning circuit can provide resonant matching. The generator can convert mechanical energy into electrical energy by using one or more varying magnetic fields and one or more electrically conductive coils. The coil can be used as an inductor having an inductive reactance that is proportional to the operating frequency of the mechanical components of the generator, such as a film. As the size of the coil increases, the reactance (resistance) to the current increases for the operating frequency of a given generator. If the generated current lags the generator eight (: voltage, efficiency loss may occur. The current in the AC system may tend to lead voltage, so the combination of the inductance of the generator and the appropriate choice of the capacitance of the power regulating circuit can be used. Tuned to resonate with the frequency of the moving parts of the generator (ie, the thin turns). At resonance, the capacitive reactance and the inductive reactance cancel each other out, and more than one power can be delivered to the load. The power conditioning circuit can further provide a A power storage component that utilizes one of the power conditioning circuits to enable the functionality to store a large amount of electrical energy at the DC voltage. This is particularly useful where a low power generator is required to supply more power that needs to be continuously available. The application of the load. In this application, the power conditioning unit can be used to - the appropriate size ^ 131870.doc -18 - 200911391 electric valley benefits until the required energy is achieved, wherein the capacitor is separate or the power adjustment One of the components of the circuit. Compared to the various modes of operation that can be implemented simultaneously with the provided power conditioning circuit, low power AC The generator can only be rectified and boosted in a number of separate operations. For example, it may typically require a bridge rectifier and a separate step-up/step-down converter to increase the voltage. In other words, most low voltage AC generators A much more expensive device is needed in addition to a rectifier to implement the circuit of Figure 3a. The cost can also be a significant advantage of the circuit shown in Figure h; in large quantities, the cost Can be estimated to be about 25, while the traditional buck/boost converter and rectifier power conditioning combination cost 10 to 20 times more. The power conditioning circuit has been specifically designed to meet the wind turbine described in this application Need; however, it can also be applied to cheap and efficient regulation of electricity generated by other low-voltage, low-power generators (such as vibration generators, linear generators). Also, note that By means of the variants of the above-mentioned circuits, the electrical outputs of the generators are illustrated. The diagram illustrates the circuit capable of combining the outputs of the two solid generators. For example, the dual-force regulation circuit can be operated in a common or separate operation. By having dual power, that is, the invention can achieve the operation of more than one power generation mechanism of the generator - then The application of electricity, for example, selectively combines the outputs with a voltage or current by means of a switch that is not shown. The power between the kings is switched by a plurality of power regulating circuits to be connected in series or in parallel, or separately.

However, two applications can be applied by means of This can be used to separate a certain distance from the inductor or to apply a 'ferred' wire with a ferrite coil to adjust a given circuit to a variety of generator sizes (with Characteristic frequency) - Some additional variations worth mentioning relate to the tensioning film 8. In some arrangements, the front and rear edges of the film can be tensioned to varying degrees, at a lower wind speed. In other cases, the generator may no longer be able to convert the fluid flowing from both sides of the generator. Similarly, the magnet can not be directly mounted on the center line of the film, but can be more sinned by nearly 4 membranes. One edge (such as the front edge or the rear edge) is installed. Thus, 131870.doc -20- 200911391 can motivate a self-starting oscillation and can also generate a larger energy oscillation in some configurations. A particular moment of wind speed variably strains the film' to produce a higher vibration frequency at higher wind speeds without the need for significantly larger displacements of the film. Can help at a low wind speed for a particular generator Another feature of the threshold that forces the membrane 8 to oscillate may involve a supercapacitor. The supercapacitor (which may be charged by an external component or by the generator itself) can discharge a current pulse to the generator line The current pulses that are passed through the coil may form a magnetic field that repels or attracts the film-mounted magnet; this repulsive or attractive force has not been forced to force the film into oscillation at a low wind speed that does not otherwise induce the film to enter a regular oscillation. The discharge of the supercapacitor into the coil can be controlled by any number of timing circuits or circuits triggered by external wired or wireless components. In addition, when the film oscillates just below the low threshold of the excitation, the discharge can be performed by the generator itself. The resulting low voltage signal is triggered. Although many variations of the generators described herein may be present, the particular dimensions of the film 8 and the layout and geometry of the magnets 4a, 4b may be important to construct an effective generator system. It has been determined that the length to width ratio of one of the films 8 from about 2:1 to 1 〇〇〇: 丨 may be important for establishing a high-energy flashing chattering oscillation system, but the ratio is highly dependent on the film of the generator and others. The physical characteristics of the component. For example, the length to width ratio of the film can range from 30:1 to 1〇〇〇:1, or from 35:1 to 1〇〇:1. The magnets can have various shapes oriented in various magnetic fields, such as discs or rectangles.
