DETAILED DESCRIPTION OF THE INVENTION

[0012] Referring to the drawings and initially to FIGS. 1-3, a modularized transformer 1 in accordance with the preferred embodiment of the present invention comprises an annular iron core 10, a first module 11 encircling the annular iron core 10, a second module 12 encircling the first module 11, a third module 13 encircling the second module 12, a fourth module 14 encircling the third module 13, and a primary-side power supply line 2 mounted on the fourth module 14 and encircling the annular iron core 10.

[0013] The annular iron core 10 is placed in the first module 11. The first module 11 is placed in the second module 12. The first module 11 is a conducting metal made of copper and has an annular shape. The second module 12 is placed in the third module 13. The second module 12 is a conducting metal made of copper and has an annular shape. The third module 13 is placed in the fourth module 14. The third module 13 is a conducting metal made of copper and has an annular shape. The fourth module 14 is a conducting metal made of copper and has an annular shape.

[0014] In such a manner, the first module 11, the second module 12, the third module 13, and the fourth module 14 overlap each other layer by layer to construct four layers of conducting metal.

[0015] Similarly, multiple modules overlap each other to extend outward successively so that the modularized transformer has multiple layers of conducting metal to produce a high voltage or high current.

[0016] The primary-side power supply line 2 is a winding wire made of copper and has a first terminal R and a second terminal S connected to a power supply.

[0017] In practice, the primary-side power supply line 2 constructs a primary-side winding, while the first module 11, the second module 12, the third module 13, and the fourth module 14 constructs a secondary-side winding. Thus, the secondary-side winding cooperates with the primary-side winding to produce a secondary-side voltage and a secondary-side current. It is noted that, the primary-side winding is connected to a power supply to input the power, and the secondary-side winding is connected to a load to output the power.

[0018] In the preferred embodiment of the present invention, an outer ring of the second module 12 has a diameter more than that of an outer ring of the first module 11, and an inner ring of the second module 12 has a diameter less than that of an inner ring 111 of the first module 11. Similarly, an outer ring of the third module 13 has a diameter more than that of an outer ring of the second module 12, and an inner ring of the third module 13 has a diameter less than that of an inner ring of the second module 12. Similarly, an outer ring 140 of the fourth module 14 has a diameter more than that of an outer ring of the third module 13, and an inner ring 141 of the fourth module 14 has a diameter less than that of an inner ring of the third module 13. Thus, the first module 11, the second module 12, the third module 13, and the fourth module 14 overlap layer by layer to construct four layers of conducting metal, thereby producing an induction voltage.

[0019] In the preferred embodiment of the present invention, the first module 11, the second module 12, the third module 13, and the fourth module 14 are connected serially. In practice, the first module 11 has a first circuit output terminal U1 electrically connected to a first output port U and a second circuit output terminal V1 electrically connected to a first circuit output terminal U2 of the second module 12, the second module 12 has a second circuit output terminal V2 electrically connected to a first circuit output terminal U3 of the third module 13, the third module 13 has a second circuit output terminal V3 electrically connected to a first circuit output terminal U4 of the fourth module 14, and the fourth module 14 has a second circuit output terminal V4 electrically connected to a second output port V. The first circuit output terminal U1 of the first module 11 is mounted on the inner ring 111 of the first module 11. The second circuit output terminal V4 of the fourth module 14 is mounted on the outer ring 140 of the fourth module 14.

[0020] In such a manner, the second circuit output terminal V1 of the first module 11 is electrically connected to the first circuit output terminal U2 of the second module 12 by a copper plate, the second circuit output terminal V2 of the second module 12 is electrically connected to the first circuit output terminal U3 of the third module 13 by a copper plate, and the second circuit output terminal V3 of the third module 13 is electrically connected to the first circuit output terminal U4 of the fourth module 14 by a copper plate, so that the first module 11, the second module 12, the third module 13, and the fourth module 14 are connected serially. Thus, the voltage is increased gradually through the first module 11, the second module 12, the third module 13, and the fourth module 14 to construct a secondary-side modularized transformer 1 with a high voltage and a low current.

[0021] In the preferred embodiment of the present invention, the annular iron core 10 is made of iron powder, a nanocrystalline, a non-silicon or a silicon steel sheet.

[0022] Referring to FIG. 4 with reference to FIGS. 1-3, the modularized transformer 1 further comprises a fifth module 15 encircling the fourth module 14. The fourth module 14 is placed in the fifth module 15. In practice, an outer ring 150 of the fifth module 15 has a diameter more than that of the outer ring 140 of the fourth module 14, and an inner ring 151 of the fifth module 15 has a diameter less than that of the inner ring 141 of the fourth module 14. Thus, the number of the modules is increased successively to produce a determined voltage or current that satisfies the user’s requirement. The fifth module 15 has a small volume to reduce the whole volume of the modularized transformer 1 so that the modularized transformer 1 has a high efficiency with a smaller volume.

[0023] Referring to FIG. 5 with reference to FIGS. 1-3, the first module 11, the second module 12, the third module 13, and the fourth module 14 are connected in parallel. In practice, a first output port U, a first circuit output terminal U1 of the first module 11, a first circuit output terminal U2 of the second module 12, a first circuit output terminal U3 of the third module 13, and a first circuit output terminal U4 of the fourth module 14 are electrically connected serially, while a second circuit output terminal V1 of the first module 11, a second circuit output terminal V2 of the second module 12, a second circuit output terminal V3 of the third module 13, a second circuit output terminal V4 of the fourth module 14, and a second output port V are electrically connected serially. Thus, the secondary-side modularized transformer 1 produces a high current and a low voltage.

[0024] Accordingly, the modularized transformer 1 has a modularized structure and includes multiple modules that are connected serially or connected in parallel, and the number of the modules is extended and increased to amplify the voltage or current continuously and to regulate the voltage or current at the required value so as to satisfy the requirement of the industry. In addition, the modularized transformer 1 has a smaller volume with a higher efficiency. Further, the modularized transformer 1 has a lower cost of fabrication. Further, the modularized transformer 1 has a great heat radiating system. Further, the modularized transformer 1 is assembled quickly and conveniently to reduce the cost. Further, the modularized transformer 1 has a lighter weight.

It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the scope of the invention.
