Description

Technical Field

[0001] The present invention relates to the field of power supply, and in particular to a power bus device and a power supply device. Background Art

[0002] A DC power supply generates a high-voltage output by connecting its internal power modules in series, or a high-current output by connecting them in parallel. However, the connection method of the power modules within a DC power supply is fixed at the factory as either series or parallel. In other words, a single DC power supply can only provide one output method (e.g., high-voltage output or high-current output) and cannot provide both output methods for users to choose from. This makes it impossible to meet the diverse needs of users with a single DC power supply. Summary of the Invention

[0003] In view of the above, the present invention provides a power bus device and a power supply device. The power bus device includes two output contacts, multiple insulation layers, multiple routing layers, multiple power supply contact groups, and multiple switching contact groups. The routing layers and the insulation layers are stacked in an alternating manner. The power supply contact groups penetrate the insulation layers and the routing layers. Each power supply contact group is connected to a power module. Each power supply contact group includes a first power supply contact and a second power supply contact. The switching contact groups respectively include a first switching contact, a second switching contact, and a switching switch. The first switching contact and the second switching contact penetrate the insulation layers and the routing layers. The switching switch connects the first switching contact and the second switching contact, and the switching switch turns on or off the connection between the first switching contact and the second switching contact according to its switching state. Multiple traces are distributed across these trace layers, connecting the two output contacts, each switching contact group, and each power supply contact group. Depending on the switching state of each switch, these power supply contact groups are connected in series or in parallel. When the power supply contact groups are connected in series, the two output contacts output the power generated by the power modules connected in series. When the power supply contact groups are connected in parallel, the two output contacts output the power generated by the power modules connected in parallel.

[0004] The power supply device includes multiple power modules and a power bus device. The power bus device includes two output contacts, multiple insulation layers, multiple routing layers, multiple power supply contact groups, and multiple switching contact groups. The routing layers and the insulation layers are stacked and arranged in an alternating pattern. The power supply contact groups penetrate the insulation layers and the routing layers and connect to the power modules. Each power supply contact group includes a first power supply contact and a second power supply contact. The switching contact groups respectively include a first switching contact, a second switching contact, and a switching switch. The first switching contact and the second switching contact penetrate the insulation layers and the routing layers. The switching switch connects the first switching contact and the second switching contact, and the switching switch opens or closes the connection between the first switching contact and the second switching contact according to its switching state. Multiple traces are distributed across these trace layers, connecting the two output contacts, each switching contact group, and each power supply contact group. Depending on the switching state of each switch, these power supply contact groups are connected in series or in parallel. When the power supply contact groups are connected in series, the two output contacts output the power generated by the power modules connected in series. When the power supply contact groups are connected in parallel, the two output contacts output the power generated by the power modules connected in parallel.

[0005] In summary, according to some embodiments, the present invention can simultaneously provide two output modes (specifically, one output mode is the power generated by connecting each power module in series, and the other output mode is the power generated by connecting each power module in parallel) for users to choose from, so that a single device can meet the different usage needs of users.

[0070] Reference Figure 1 and Figure 2 . Figure 1 FIG. 1 is a front view of a power supply device 10 according to a first embodiment of the present invention. Figure 2 This is a schematic side view of a power bus device 30 according to a first embodiment of the present invention. The power supply device 10 includes multiple power modules and a power bus device 30. The power bus device 30 includes two output contacts (i.e., a first output contact 40A and a second output contact 40B), multiple insulation layers 50, multiple trace layers 60, multiple power supply contact groups, and multiple switching contact groups. Figure 1 Two power modules (i.e., first power module 20A and second power module 20B), two power supply contact groups (i.e., first power supply contact group 70A and second power supply contact group 70B), and three switching contact groups (i.e., first switching contact group 80A, second switching contact group 80B, and third switching contact group 80C) are shown here, but the present invention is not limited to this. The number of power modules, power supply contact groups, and switching contact groups can be adjusted according to user needs. The first output contact 40A and the second output contact 40B are connected to an external load device to supply power to the external load device. In some embodiments, the power module can be a DC power module.

[0071] The wiring layers 60 and the insulation layers 50 are stacked alternately so that different wiring layers 60 can be isolated from each other and are not interfered with each other. Figure 2 Three wiring layers 60 and two insulation layers 50 are drawn here, but the present invention is not limited thereto. The number of wiring layers and insulation layers can be adjusted according to user needs.

[0072] The first power contact set 70A and the second power contact set 70B penetrate the insulation layers 50 and the routing layers 60 and connect to the first power module 20A and the second power module 20B, respectively. Because the first power contact set 70A and the second power contact set 70B have the same composition and function, for the sake of simplicity, only the first power contact set 70A will be used as an example for this description. The first power contact set 70A includes a first power contact CH1+ and a second power contact CH1-. The two output terminals of the first power module 20A are connected to the first power contact CH1+ and the second power contact CH1-, respectively.

[0073] Next, the first switching contact group 80A, the second switching contact group 80B, and the third switching contact group 80C are further described. Since the first switching contact group 80A, the second switching contact group 80B, and the third switching contact group 80C have the same composition and function, for the sake of simplicity, only the first switching contact group 80A is used as an example for description. The first switching contact group 80A includes a first switching contact SW1A, a second switching contact SW2A, and a switch 81A. The first switching contact SW1A and the second switching contact SW2A penetrate the insulating layer 50 and the wiring layer 60. The switch 81A connects the first switching contact SW1A and the second switching contact SW2A, and switches the first switching contact SW1A and the second switching contact SW2A to open or close the connection depending on its switching state.

[0074] In some embodiments, the switches 81A of the first switching contact group 80A can be implemented as electronic switches, such as relays. In some embodiments, the first switching contact group 80A further includes an isolation slot 82 extending through the insulating layers 50 and the wiring layers 60. The isolation slot 82 is located between the corresponding first switching contact SW1A and the second switching contact SW2A. The isolation slot 82 accommodates an isolation member (e.g., a plastic sheet) of the corresponding switching switch 81A. This ensures that when the switching switch 81A disconnects the first switching contact SW1A from the second switching contact SW2A, the first switching contact SW1A and the second switching contact SW2A are isolated from each other and do not interfere with each other.

[0075] Each routing layer 60 is distributed with a plurality of routing lines. The routing lines of the routing layers 60 connect two output contacts (i.e., the first output contact 40A and the second output contact 40B), the power supply contact groups (e.g., the first power supply contact group 70A and the second power supply contact group 70B), and the switching contact groups (e.g., the first switching contact group 80A, the second switching contact group 80B, and the third switching contact group 80C). Depending on the switching state of the switches in each switching contact group, the power supply contact groups are connected in series or in parallel. When the power supply contact groups are connected in series, the two output contacts output the power generated by the power modules (e.g., the first power module 20A and the second power module 20B) connected in series. When the power supply contact groups are connected in parallel, the two output contacts output the power generated by the power modules connected in parallel. In this way, the power supply device 10 can simultaneously provide two output modes (specifically, one output mode is the power generated by the series connection of the power modules to provide a high voltage output such as 2000 volts, and the other output mode is the power generated by the parallel connection of the power modules to provide a high current output such as 180 amperes) for the user to choose (for example, the output mode is selected by controlling the switching state of each switch of each switching contact group), so that a single device can meet the different usage needs of users.

[0076] In some embodiments, the power bus device 30 of the power supply device 10 further includes a relay contact 93 (eg, Figures 3 to 5 ), penetrating the insulating layers 50 and the wiring layers 60 so that the wiring layers 60 can be connected to other components.
