Abstract

The present invention relates to a magnet-based, double-magnetic-circuit, magnetic-pressure and resonant-excitation generator transformer. It comprises a magnet (1) the two opposing poles (2) (3) of which are connected to one another by a magnetic bridge. A second magnet (31) is mounted in parallel with the first magnet (1). Two magnet poles (2) (32) are connected to the same external pole (6) of the magnetic bridge. Two other magnet poles (3) (33) are connected to the same external pole (7) of the magnetic bridge. The invention comprises four electromagnets (13) acting as a reversible magnetic diode. The magnetic bridge comprises a common magnetic core (9), a primary magnetic circuit. The common magnetic core (9) connects the two internal poles (8) of the primary magnetic circuit to one another. The magnetic bridge and the four electromagnets (13) together form a reversible magnetic diode bridge that makes it possible to convert a continuous magnetic flux into a variable magnetic flux. The excitation solenoid (12) and the power solenoid (11) are wound around the common magnetic core (9). These two solenoids are placed inside the secondary magnetic circuit (30). When the cores of the four electromagnets (13) and the core of the excitation solenoid (12) are polarized in a specific way, the excitation flux (15) (20) and the magnet flux (14) circulate together, in one direction, through the common magnetic core (9). When this polarization is reversed, the excitation flux (15) (20) and the magnet flux (14) circulate together, in the opposite direction, through the common magnetic core (9). The alternating and continuous reversal of the direction of circulation of the excitation flux (15) (20) reinforced by a magnet flux (14) creates a variable magnetic flux that circulates in the common magnetic core. This induction flux, reinforced by a magnet flux, increases the power developed at the power solenoid (11). Mounting a plurality of magnets in parallel makes it possible to create a magnetic pressure at the magnetic bridge and reinforce the variation of the flux. The use of a resonant excitation circuit makes it possible to compensate for the high inductance of the electromagnets. The present invention makes it possible to significantly increase the efficiency of a transformer. It may be used by any industry requiring electrical energy, including the electronics industry, the automotive industry and the aeronautical industry. A 100 kW transformer would measure 20x20x30 cm.

Description

[0001] DESCRIPTION

[0002] Title of the invention: Magnet transformer-generator, with double magnetic circuits, magnetic pressure and resonant excitation.

[0003] The present invention relates to a double magnetic circuit, magnetic pressure, and resonant excitation magnet transformer-generator. It uses a magnet's magnetic flux to reinforce the excitation flux of a transformer, in order to increase efficiency. It also uses a double magnetic circuit to optimize the flow of flux in the system. It uses the magnetic pressure created by two magnet poles of the same polarity to accentuate the flux variation at the power solenoid.

[0004] In the patent literature, WO 2022 / 224 OU A1 describes a magnet generator that channels the magnet's magnetic flux into two separate magnetic cores to reinforce the excitation solenoid's flux flowing into another magnetic core. This configuration degrades the system's performance. US Patent 6,362,718 B1 describes a generator that channels a magnet's magnetic flux alternately into two different magnetic cores to induce two separate power solenoids. This configuration also proves to be inefficient considering that the magnet induces only one power solenoid at a time.

[0005] The present invention proposes a solution for injecting a magnet flux into the magnetic circuit of a transformer and using this magnet flux to reinforce the excitation flux. The magnet flux and the excitation flux circulate at the same time in the same magnetic core to induce a power solenoid. The efficiency of the transformer increases proportionally with the density of the injected magnet flux. This new technique can also be used to convert a continuous magnetic flux into a variable magnetic flux.

[0006] When two magnet poles (2) (3), of opposite polarity, are connected to each other by a magnetic path (53), a continuous magnet flux (14) circulates between these two poles (2)(3), in the absence of magnetic constraints. These two poles (2)(3) can belong to a magnet (1). But these two poles (62)(63) can belong to two separate magnets (64)(65). When this magnetic path (53) comprises two circuits (54)(55) in parallel, the magnet flux (14) coming from the north pole (2) chooses one (54) or the other (55) circuit in parallel to reach the south pole (3). A magnetic constraint applied to one or both circuits in parallel, at the same time, makes it possible to impose a trajectory on the magnet flux circulating between the north pole (2) and the south pole (3). An electromagnet, an excitation solenoid or a magnetic diode are used to apply stresses to a magnetic circuit.An electromagnet is placed in each of the two magnetic paths (54)(55) connected in parallel. A specific polarization (58)(59) of the magnetic cores of the two electromagnets (56)(57) channels the magnet flux (14) into one (55) of the magnetic paths. A reversal of this polarization (60)(61) channels the magnet flux (14) into the other (54) magnetic path.

[0007] In the present invention, we will use a primary magnetic circuit to create two magnetic paths, mounted in parallel, to connect two magnet poles (2)(3) of opposite polarity. The primary magnetic circuit has two internal poles (8) and two external poles (6)(7). The two internal poles (8) of the primary magnetic circuit are connected to each other by a common magnetic core (9) around which a power solenoid (11) is wound. The primary magnetic circuit, the common magnetic core (9) and the power solenoid (11) together form a magnetic bridge. An excitation solenoid (12) is wound around the common magnetic core (9). This assembly is equivalent to a simple conventional transformer which uses magnetic energy to ensure the transfer of power between the primary circuit and the secondary circuit.This power transfer depends mainly on the magnetic flux density and the switching frequency. Increasing the flux density or increasing the switching frequency or both at the same time results in an increase in the transferred power.

[0008] We take a magnetic bridge that will be used throughout our presentation. We connect one external pole (6) of the magnetic bridge to a magnet pole (2), by a magnetic path (4), and we connect the other external pole (7) to another magnet pole (3) of opposite polarity. We wind an excitation solenoid (12) around the common magnetic core (9). The magnet flux (14) has two magnetic paths in parallel between the two external poles (6)(7) of the magnetic bridge. In the absence of magnetic constraint, a magnet flux (14) flows from the north pole (2) to the south pole (3) without passing through the common magnetic core (9). The magnet flux (14) flows only through the primary magnetic circuit. A bias (16)(17) of the magnetic core of the excitation solenoid (12) allows the magnet flux (14) to be channeled, in one direction, through the common magnetic core (9).A reversal of this polarization (18) (19) channels the magnet flux (14), in the opposite direction, through the common magnetic core (9). This magnet flux (14) circulates together with the excitation flux (15).

[0009] The excitation solenoid (12) is replaced by four electromagnets (13) and the four electromagnets (13) are arranged in the magnetic bridge. Each magnetic path (10) connecting an external pole (6)(7) to an internal pole (8) of the magnetic bridge comprises an electromagnet (13). A specific polarization (21)(22) of the magnetic cores of the four electromagnets (13) allows a magnet flux (14) to be channeled in one direction through the common magnetic core (9). A reversal of this polarization (23)(24) channels this magnet flux (14) in the opposite direction. This magnet flux (14) circulates together with the excitation flux (20) generated by the electromagnets.

[0010] The excitation solenoid (12) is replaced. The four electromagnets (13) can work together with the excitation solenoid (12). A specific polarization (26) (27) of the magnetic cores of the four electromagnets (13) and of the magnetic core of the excitation solenoid (12) allows the magnet flux (14) to be channeled in one direction through the common magnetic core (9). A reversal of this polarization (28)(29) channels this magnet flux, in the opposite direction, through the common magnetic core (9). This magnet flux (14) circulates together with the excitation flux (25), generated by the electromagnets and the excitation solenoid.

[0011] The alternating and continuous reversal of the direction of circulation of the excitation flux reinforced by a magnet flux (14), in the common magnetic core (9), creates a variable magnetic flux resulting in a generation of alternating current at the power solenoid (11). The induction flux being a combination of the excitation flux (15) (20) (25) with a magnet flux (14), the efficiency of the transformer increases accordingly.

[0012] Two magnetic cores are connected to the common magnetic core (9) to form a secondary magnetic circuit (30). The power solenoid (11) and the excitation solenoid (12) are placed inside this secondary magnetic circuit (30). The secondary magnetic circuit (30) will have a lower reluctance than the primary magnetic circuit due to the absence of magnetic constraint. The flux (15) generated by the excitation solenoid (12) and the self-induction flux of the power solenoid (11) will circulate largely in the secondary magnetic circuit (30). The excitation flux (20) generated by the electromagnets (13) circulates in the primary magnetic circuit. This optimization of the flux circulation improves the performance of the system. Given the high inductance of an electromagnet, the use of a resonant excitation circuit allows the excitation flux density to be correctly calibrated.

[0013] The magnetic bridge associated with the four electromagnets together form a device for converting a continuous magnetic flux into a variable magnetic flux. If an invertible magnetic diode exists, the four electromagnets (13) can be replaced by four invertible magnetic diodes (40). An invertible magnetic diode (40) is characterized by its ability to allow the magnetic flux to flow freely in one direction, and to strongly restrict this flow in the opposite direction. The direction of circulation of the magnetic flux can be controlled by biasing the invertible magnetic diode (40) using an electrical signal. A magnetic bridge associated with four invertible magnetic diodes together form an invertible magnetic diode bridge. Each magnetic path (10) connecting an external pole (6) (7) of the invertible magnetic diode bridge to an internal pole (8) comprises an invertible magnetic diode (40).

[0014] An invertible magnetic diode bridge is taken. The external pole (6) of the invertible magnetic diode bridge is connected to a magnet pole (2) by a magnetic path (4), and the other external pole (7) is connected to a magnet pole (3) of opposite polarity. A specific polarization (41)(42) of the four invertible magnetic diodes (40) makes it possible to channel a magnet flux (14), in one direction, through the common magnetic core (9). A reversal of this polarization channels the magnet flux (14) in the opposite direction. The two poles (2)(3), of opposite polarity, of the magnet (1) constitute in this configuration a source of continuous magnetic flux. The alternating and continuous reversal of the direction of circulation of the magnet flux (14), in the common magnetic core (9), creates a variable magnetic flux resulting in a generation of alternating current at the power solenoid (11).This magnet flux (14) can be reinforced by the flux (15) of an excitation solenoid (12) wound around the common magnetic core (9). The circulation of the excitation flux can be optimized by the use of a secondary magnetic circuit (30).

[0015] All configurations of the invention may comprise one or more magnets. Several magnets may be mounted in series or in parallel. When the system comprises several magnets, mounted in parallel, each external pole of the magnetic bridge is connected to several magnet poles of the same polarity. This configuration makes it possible to create a magnetic pressure at the external poles (6)(7) of the magnetic bridge, and to accentuate the flux variation with each reversal of the direction of circulation of the flux. All configurations of the invention may comprise several primary magnetic circuits mounted in parallel, but with a common magnetic core (71) shared between several primary magnetic circuits (69)(70). A common magnetic core (71) connects together the two internal poles (8) of several primary magnetic circuits (69)(70).Each primary magnetic circuit can be connected to two poles (72)(73) of magnet of opposite polarity, belonging to two different magnets. But each primary magnetic circuit can be connected to the two poles, of opposite polarity, of a magnet.

[0016] In all configurations of the invention, each magnet may be reinforced or replaced by an electromagnet. The primary magnetic circuit may include one or more air gaps. The secondary magnetic circuit may include one or more air gaps.

[0017] The first configuration of the invention comprises at least one magnet (1), one magnetic bridge and one excitation solenoid (12). One outer pole (6) of the magnetic bridge is connected to one magnet pole (2), while the other outer pole (7) of the magnetic bridge is connected to one magnet pole (3), of opposite polarity. The excitation solenoid (12) is wound around the common magnetic core (9). The excitation flux (15) is reinforced by a magnet flux (14).

[0018] The second configuration of the invention comprises at least one magnet (1), one magnetic bridge, and four electromagnets (13). One external pole (6) of the magnetic bridge is connected to a magnet pole (2), while the other external pole (7) of the magnetic bridge is connected to a magnet pole (3), of opposite polarity. Each of the four magnetic paths (10) connecting an external pole (6)(7) to an internal pole (8) of the primary magnetic circuit comprises an electromagnet (13). The excitation flux (20) generated by the electromagnets (13) is reinforced by a magnet flux (14).

[0019] The third configuration of the invention is identical to the second configuration except that it additionally comprises an excitation solenoid (12) which is wound around the common magnetic core (9). Its excitation is synchronized with the four electromagnets (13) in order to make them operate in synergy. The excitation flux (25) is reinforced by a magnet flux (14).

[0020] The fourth configuration of the invention is identical to the third configuration except that it additionally comprises a secondary magnetic circuit (30). The power solenoid (11) and the excitation solenoid (12) are placed in the secondary magnetic circuit (30). The fifth configuration of the invention is identical to the first configuration except that it additionally comprises four invertible magnetic diodes (40). Each of the four magnetic paths (10) connecting an external pole (6) (7) to an internal pole (8) of the primary magnetic circuit comprises an invertible magnetic diode (40).

[0021] The sixth configuration of the invention is identical to the fifth configuration except that it additionally comprises a secondary magnetic circuit (30). The power solenoid (11) and the excitation solenoid (12) are placed in the secondary magnetic circuit (30).

[0022] The seventh configuration of the invention is identical to the fifth configuration except that it does not include any excitation solenoid (12). The four invertible magnetic diodes (40) alone ensure the channeling of the magnet flux (14) through the common magnetic core (9).
