Description

[Technical Field]

[0001] The present invention relates to the field of power supplies, and more particularly to power bus bar devices and power supply devices. [Background technology]

[0002] A DC power supply generates and outputs a high voltage by connecting its internal power modules in series, or generates and outputs a large current by connecting its internal power modules in parallel. However, the connection method of the power modules inside the DC power supply is fixed to either series or parallel connection when shipped from the factory. In other words, a single DC power supply can only provide one output mode (such as high voltage output or high current output), but cannot simultaneously provide two output modes for user selection. Therefore, it has been impossible to meet various user needs using only a single DC power supply. Summary of the Invention [Means for solving the problem]

[0003] The present invention has been made in view of the above circumstances and provides a power bus bar device and a power supply device. The power bus bar device includes two output contacts, multiple insulating layers, multiple trace layers, multiple power feed contact sets, and multiple switching contact sets. The multiple trace layers and the multiple insulating layers are alternately stacked. The multiple power feed contact sets penetrate the multiple insulating layers and the multiple trace layers. Each power feed contact set is used to connect a power module. Each power feed contact set has a first power feed contact and a second power feed contact. The multiple switching contact sets each have a first switching contact, a second switching contact, and a changeover switch. The first switching contact and the second switching contact penetrate the multiple insulating layers and the multiple trace layers. The changeover switch connects the first switching contact and the second switching contact, and makes or breaks the connection between the first switching contact and the second switching contact depending on a switching state. The traces connecting the two output contacts, each of the changeover contact sets, and each of the power supply contact sets are distributed on the trace layers, and are connected in series or parallel to the power supply contact sets according to the switching state of each of the changeover switches. When the power supply contact sets are connected in series, the two output contacts output the power generated after the power modules are connected in series, and when the power supply contact sets are connected in parallel, the two output contacts output the power generated after the power modules are connected in parallel.

[0004] The power supply device includes a plurality of power modules and a power bus bar device. The power bus bar device includes two output contacts, a plurality of insulating layers, a plurality of trace layers, a plurality of power feed contact sets, and a plurality of switching contact sets. The plurality of trace layers and the plurality of insulating layers are alternately stacked. The plurality of power feed contact sets penetrate the plurality of insulating layers and the plurality of trace layers and connect the power modules. Each of the power feed contact sets has a first power feed contact and a second power feed contact. The plurality of switching contact sets each have a first switching contact, a second switching contact, and a changeover switch. The first switching contact and the second switching contact penetrate the plurality of insulating layers and the plurality of trace layers. The changeover switch connects the first switching contact and the second switching contact and makes or breaks the connection between the first switching contact and the second switching contact depending on a switching state. A plurality of traces connecting the two output contacts, each of the changeover contact sets, and each of the power supply contact sets are distributed on the plurality of trace layers, and are connected in series or parallel to the plurality of power supply contact sets according to the switching state of each of the changeover switches. When the plurality of power supply contact sets are connected in series, the two output contacts output the power generated after the power modules are connected in series, and when the plurality of power supply contact sets are connected in parallel, they output the power generated after the power modules are connected in parallel. [Effects of the Invention]

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

DETAILED DESCRIPTION OF THE INVENTION

[0007] (First embodiment) Please refer to FIGS. 1 and 2. FIG. 1 is a schematic front view of a power supply apparatus 10 according to a first embodiment of the present invention. FIG. 2 is a schematic side view of a power bus bar apparatus 30 according to the first embodiment of the present invention. The power supply apparatus 10 includes a plurality of power modules and the power bus bar apparatus 30. The power bus bar apparatus 30 includes two output contacts (i.e., a first output contact 40A and a second output contact 40B), a plurality of insulating layers 50, a plurality of trace layers 60, a plurality of power feed contact sets, and a plurality of switching contact sets. While FIG. 1 illustrates two power modules (i.e., a first power module 20A and a second power module 20B), two power feed contact sets (i.e., a first power feed contact set 70A and a second power feed contact set 70B), and three switching contact sets (i.e., a first switching contact set 80A, a second switching contact set 80B, and a third switching contact set 80C), the present invention is not limited thereto, and the number of power modules, power feed contact sets, and switching contact sets can be adjusted according to user needs. The first output contact 40A and the second output contact 40B are used to connect to an external load device to supply power to the external load device. In some embodiments, the power module may be a DC power module.

[0008] The multiple trace layers 60 and multiple insulation layers 50 are arranged in an alternating stack such that different trace layers 60 are separated from each other and do not interfere with each other. Although Fig. 2 shows three trace layers 60 and two insulation layers 50, the present invention is not limited thereto, and the number of trace layers and insulation layers can be adjusted according to the needs of the user.

[0009] The first and second power supply contact sets 70A and 70B penetrate the multiple insulating layers 50 and the multiple trace layers 60 to connect the first and second power modules 20A and 20B, respectively. The first and second power supply contact sets 70A and 70B have the same configuration and function, and for simplicity's sake, only the first power supply contact set 70A will be described here. The first power supply contact set 70A has a first power supply contact CH1+ and a second power supply contact CH1-, and the two output ends of the first power module 20A are connected to the first power supply contact CH1+ and the second power supply contact CH1-, respectively.

[0010] Next, the first set of switching contacts 80A, the second set of switching contacts 80B, and the third set of switching contacts 80C will be further described. The first set of switching contacts 80A, the second set of switching contacts 80B, and the third set of switching contacts 80C have the same configurations and functions. For simplicity, only the first set of switching contacts 80A will be described here. The first set of switching contacts 80A includes a first switching contact SW1A, a second switching contact SW2A, and a changeover switch 81A. The first switching contact SW1A and the second switching contact SW2A penetrate the multiple insulating layers 50 and the multiple trace layers 60. The changeover switch 81A connects the first switching contact SW1A and the second switching contact SW2A and makes or breaks the connection between the first switching contact SW1A and the second switching contact SW2A depending on the switching state.

[0011] In some embodiments, the changeover switch 81A of the first changeover contact set 80A may be realized by an electronic switch such as a relay. In some embodiments, the first changeover contact set 80A further includes an isolation groove 82 penetrating the plurality of insulating layers 50 and the plurality of trace layers 60, the isolation groove 82 being located between the corresponding first changeover contact SW1A and the second changeover contact SW2A. The isolation groove 82 accommodates an isolation member (e.g., a plastic sheet) of the corresponding changeover switch 81A, so that the first changeover contact SW1A and the second changeover contact SW2A are isolated from each other and do not interfere with each other when the changeover switch 81A breaks the connection between the first changeover contact SW1A and the second changeover contact SW2A.

[0012] Each trace layer 60 is distributed with a plurality of traces. The plurality of traces of the plurality of trace layers 60 connect two output contacts (i.e., the first output contact 40A and the second output contact 40B), a plurality of power feed contact sets (e.g., the first power feed contact set 70A and the second power feed contact set 70B), and a plurality of switching contact sets (e.g., the first switching contact set 80A, the second switching contact set 80B, and the third switching contact set 80C), and connect the plurality of power feed contact sets directly or in parallel depending on the switching state of the selector switch of each switching contact set. When the plurality of power feed contact sets are connected in series, the two output contacts output the power generated after the plurality of power modules (e.g., the first power module 20A and the second power module 20B) are connected in series. When the plurality of power feed contact sets are connected in parallel, the two output contacts output the power generated after the plurality of power modules are 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 after multiple power modules are connected in series to provide a high voltage output such as 2000 volts, and the other output mode is the power generated after multiple power modules are connected in parallel to provide a high current output such as 180 amperes) for user selection (e.g., by controlling the switching state of each switch in each switching contact group to select the output mode) so that a single device can meet various user usage needs.

[0013] In some embodiments, the power bus bar device 30 of the power supply device 10 further includes relay contacts 93 (FIGS. 3-5) that penetrate the multiple insulation layers 50 and the multiple trace layers 60 to connect the multiple traces of the multiple trace layers 60 to other elements.

In some embodiments, as shown in FIG. 3, the thickness of the trace layer 60 is greater than the thickness of the insulation layer 50, e.g., the thickness of the trace layer 60 is 2 mm, while the thickness of the insulation layer 50 is 1 mm. In some embodiments, an insulating paint may be applied to the surfaces of the trace layer 60 and the insulation layer 50 to enhance the insulating effect. In some embodiments, the coating thickness of the insulating paint may be in the range of 0.15 mm to 0.25 mm.
