Description

Referring to Fig. 1, a conventional transformer, such as a transformer 1 composed of an E-core and an I-core, has a primary coil 11 and a secondary coil 12 wound around a core in a tight coupling manner. Above, and since the conventional core is usually made of a single material, the innate material property limitation is such that an air gap is required between the cores to avoid magnetic saturation, but a negative magnetic damping effect is also generated, so that the output energy is less than the input energy, that is, The gain value is always less than 1, and the back electromotive force of the output terminal OUT directly hits the input terminal IN, and the eddy current loss is large, so even if the conversion efficiency of the transformer 1 is high, only the transfer or transfer of electric energy can be performed.

Therefore, the object of the present invention is to provide a switched reluctance transformer having a positive magnetic damping effect.

Therefore, the novel switched reluctance transformer comprises a core unit and at least one coil; the core unit has a "day" shape and is composed of at least one core material and has both inductive and capacitive properties; the coil and the iron The core unit is loosely coupled to the core unit.

Preferably, the core unit comprises a capacitive and generalized a first silicon steel sheet group and a second silicon steel sheet group, and an inductive and generally "day" shaped amorphous core, wherein the first silicon steel sheet group and the second silicon steel sheet The group is respectively fixed on opposite sides of the amorphous core to form the core unit, and the switched reluctance transformer comprises a first coil which is loosely coupled with the core unit and is respectively disposed on opposite sides of the core unit. a second coil.

The present invention provides both inductive and capacitive properties by providing a core unit without an air gap, and at least one coil loosely coupled around the core unit, so that when the core input unit energizes the core unit, the core unit can quickly reach magnetic saturation, and the input energy is stopped to the coil. When the core unit generates a positive magnetic damping effect, the generated eddy current is coupled to the coil, so that the output energy of the coil is greater than the input energy.

Other features and effects of the present invention will be apparent from the following description of the drawings, wherein: FIG. 1 is a schematic diagram of a conventional transformer; FIG. 2 is a first preferred embodiment of the novel switched reluctance transformer. FIG. 3 is a schematic exploded view of a second preferred embodiment of the switch-reluctance transformer of the present invention; FIG. 5 is a second comparative example of the second preferred embodiment of the switch-reluctance transformer of the present invention; FIG. 6 is a schematic exploded view of a third preferred embodiment of the novel switched reluctance transformer; and FIG. 7 is a schematic structural view of the third preferred embodiment.

The switch-type reluctance transformer mainly comprises a core unit and at least one coil wound around the core unit, wherein the core unit has a "day" shape and is composed of at least one core material to be both inductive and capacitive. And the coil is wound around the core unit and loosely coupled to the core unit.

For example, as shown in FIG. 2, the core unit 21 of the first preferred embodiment of the present invention includes a PN semiconductor core 22, such as a solid-state inductor, which is both inductive and capacitive and has a "mouth" shape (or a ring shape). , and A permanent magnet 23 provided inside the PN semiconductor core 22, together with the PN semiconductor core 22, constitutes a core having a "day" shape. The present embodiment includes a coil 24 wound around the PN semiconductor core 22. Since the coil 24 is loosely coupled with the PN semiconductor core 22, and the PN semiconductor core 22 itself and its permanent magnet 23 have no air gap, so that the energy input from the coil 24 is excited to the core unit 21, the core unit 21 may be The magnetic field of the coil 24 and the negative impedance (negative inductance) effect of the permanent magnet 23 rapidly reach magnetic saturation, and when the input energy is stopped to the coil 24, the core unit 21 generates a positive magnetic damping effect (magnetic shunt). The eddy current generated by the release of magnetic energy is coupled to the coil 24 such that the output energy of the coil 24 is greater than the input energy.

Further, the permanent magnet 23 of the present embodiment is provided in addition to the PN. Further, inside the semiconductor core 22, as shown in FIG. 3, the permanent magnet 23 may be provided on the outer side of the PN semiconductor core 22, and the magnetic saturation of the core unit 21 may be rapidly achieved when the core unit 21 is excited.

Referring to FIG. 4 and FIG. 5 again, the second preferred embodiment of the present invention The core unit 31 of the example includes an inductive manganese-zinc core 32 and a capacitive nickel-zinc core 33, and a sandwiched between the manganese-zinc core 32 and the nickel. The permanent magnet 34 between the zinc cores 33 and the manganese-zinc core 32 and the nickel-zinc core 33 together form a core of a "day" shape. Further, the present embodiment includes a coil 35 wound around one side of the manganese-zinc core 32 and the nickel-zinc core 33. Since the coil 35 is loosely coupled with the core unit 31, and there is no air gap between the manganese-zinc core 32 and the nickel-zinc core 33 and the permanent magnet 23, energy is input from the coil 35. When the core unit 31 is excited, the core unit 31 rapidly reaches magnetic saturation due to the magnetic field of the coil 35 and the negative impedance (negative inductance) effect of the permanent magnet 23, and when the input of energy to the coil 35 is stopped, the core unit 21 generates positive The magnetic damping effect (magnetic field commutation) and the eddy current generated by the release of magnetic energy are coupled to the coil 35 such that the output energy of the coil 35 is greater than the input energy.

Referring to FIG. 6 and FIG. 7 again, the third preferred embodiment of the present invention The core unit 41 of the example comprises a first silicon steel sheet group 42 and a second silicon steel sheet group 43 having a capacitive and substantially "day" shape, and an amorphous one having an inductive and substantially "day" shape. The core 44, and the first silicon steel sheet set 42 and the second silicon steel sheet set 43 are respectively fixed on opposite sides of the amorphous core 44 to form the core unit 41, and the present embodiment includes separate windings integrally coupled with the core unit 41. A first coil 45 and a second coil 46 on opposite sides of the core unit 41. Since the first coil 45 and the second coil 46 are loosely coupled with the core unit 41, the two are electrically insulated, and between the first silicon steel sheet group 42, the second silicon steel sheet group 43 and the amorphous iron core 44. There is no air gap, so that when the input energy is excited by the first coil 45 to the core unit 41, the core unit 41 rapidly reaches magnetic saturation, and when the input energy is stopped to the first coil 45, the core unit 21 generates a positive magnetic damping effect ( The magnetic field is commutated, and the eddy current generated by the release of the magnetic energy is coupled to the second coil 46 such that the output energy of the second coil 46 is greater than the input energy of the first coil 45.

In summary, the above embodiment provides a simultaneous power supply by providing a core unit that is inductively and capacitively and has no air gap, and at least one coil that is loosely coupled around the core unit, so that when the core input unit energizes the core unit, the core unit can quickly reach magnetic saturation. stop When the input energy is applied to the coil, the core unit generates a positive magnetic damping effect, and the eddy current generated by releasing the magnetic energy is coupled to the coil, so that the output energy of the coil is greater than the input energy, thereby achieving the efficacy and purpose of the novel.

However, the above is only the preferred embodiment of the present invention.
