Abstract

Technical Field
[0001] This utility model relates to the field of transformer technology, specifically to an all-in-one DC-DC high-power transformer. Background Technology
[0002] In modern electronic technology fields such as new energy, industrial control, and communication power supply, DC-DC high-power transformers are core components for power conversion and transmission, and their performance directly affects the efficiency, stability, and miniaturization level of the entire system.
[0003] The inventors discovered that at least the following problems remain unresolved in the existing technology: traditional core power devices such as main transformers, resonant inductors, and output inductors are typically designed and installed separately. This distributed layout requires each device to be positioned, fixed, and wired separately, which not only makes the final assembly process cumbersome, increases labor costs and assembly time, but also easily affects the accuracy of circuit parameter matching due to the accumulation of assembly errors of multiple devices, thus reducing the overall reliability of the system.
[0004] Therefore, we propose an all-in-one DC-DC high-power transformer that can solve the above problems. Utility Model Content

[0020] Please see Figures 1-5 This utility model provides a technical solution: a multi-functional DC-DC high-power transformer, including a main transformer 1, a resonant inductor 2, an output inductor 3, and a base plate 4; the base plate 4 is provided with a first mounting groove 41 and a second mounting groove 44, and the inner wall of the bottom end of the first mounting groove 41 is provided with a first slot 42 and a second slot 43; the main transformer 1, the resonant inductor 2, and the output inductor 3 are adapted to be installed in the first mounting groove 41, and a first insert plate 13 is vertically installed on the bottom side of the main transformer 1, and the first insert plate 13 is inserted into the first slot 42; a second insert plate 31 is vertically fixedly installed on the bottom side of the output inductor 3, and the second insert plate 31 is inserted into the second slot 43; three sets of fixing plates 47 are welded to the outer side of the base plate 4, and fixing holes 48 are opened through the upper surface of the fixing plates 47; the base plate 4 is fixedly connected to the external structure through the fixing holes 48 of the fixing plates 47 by fasteners.
[0021] This technical solution employs a multi-integrated combination of main transformer 1, resonant inductor 2, and output inductor 3, combining multiple power devices on the base to reduce final assembly steps. The selection of magnetic core model and size, along with clever spatial matching, ensures a compact assembly, minimizing space waste and maximizing space utilization. The use of multi-strand stranded wire and copper sheet coils achieves a small overall size while meeting high power requirements. Fasteners passing through the fixing holes 48 securely mount the base plate 4 to external equipment or structures, further enhancing the overall stability of the transformer during operation and ensuring long-term stable operation.
[0022] In this embodiment, there are six sets of first insert plates 13 and six sets of first slots 42. The first insert plate 13 on the bottom side of the main transformer 1 corresponds to the first slot 42 on the inner wall of the bottom end of the first mounting groove 41, and the dimensions of the first insert plate 13 and the first slot 42 are matched. There are four sets of second insert plates 31 and four sets of second slots 43. The second insert plate 31 on the bottom side of the output inductor 3 corresponds to the second slot 43 on the inner wall of the bottom end of the first mounting groove 41, and the dimensions of the second insert plate 31 and the second slot 43 are matched.
[0023] In this technical solution, the six sets of first plug plates 13 vertically mounted on the bottom side of the main transformer 1 precisely correspond to the six sets of first slots 42 opened on the inner wall of the bottom end of the first mounting groove 41, and their dimensions are perfectly matched. The main transformer 1 is stably installed on the base plate 4 through plug-in connection. This multi-set plug-in structure effectively restricts the horizontal displacement of the main transformer 1 and ensures its stability during operation. Similarly, the four sets of second plug plates 31 on the bottom side of the output inductor 3 are plugged into the four sets of second slots 43 in the first mounting groove 41, so that the output inductor 3 can also be firmly fixed on the base plate 4.
[0024] In this embodiment, the main transformer 1 is connected to the first connector 12 via the first connecting line 11, and the resonant inductor 2 is connected to the second connector 22 via the second connecting line 21. A first insertion hole 45 is provided through the inner wall of the bottom end of the second mounting groove 44 on the side close to the main transformer 1, and a second insertion hole 46 is provided through the inner wall of the bottom end of the second mounting groove 44 on the side away from the first insertion hole 45. The second connector 22 is provided with the second insertion hole 46, and the first connector 12 and the second connector 22 are respectively inserted into the first insertion hole 45 and the second insertion hole 46.
[0025] In this technical solution, the main transformer 1 is connected to the first connector 12 via the first connecting line 11, and the resonant inductor 2 is connected to the second connector 22 via the second connecting line 21. These connectors are respectively inserted into the first socket 45 and the second socket 46 on the inner wall of the bottom end of the second mounting groove 44. This structural design not only achieves effective transmission of electrical signals but also provides a certain degree of limitation and protection for the connecting lines and connectors through the sockets, preventing poor contact caused by vibration or other reasons during operation and ensuring the reliability of the circuit connection.
[0026] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
