Description

[Technical Field]

[0001] The present invention relates to an intelligent power supply, and more particularly to an intelligent power supply with ATX12V and ATX12VO power outputs. [Background technology]

[0002] Power supplies are the main equipment of computers, and with the development of technology, power supply specifications have become more diverse, such as ATX12V, ATX3.0, and ATX12VO, among which ATX12V and ATX12VO are motherboard power supply specifications, with older motherboards using ATX12V and newer motherboards using ATX12VO for power supply, and when motherboards with two different power supply specifications are available on the market at the same time, the problem of supplying power to motherboards with different specifications must be solved.

[0003] The easiest solution is usually to purchase a power supply that matches the motherboard specifications. Currently, there are solutions available on the market that use a separate transformer circuit that converts ATX12V power to ATX12VO power (e.g., TW-M610397). In addition, some manufacturers release their own power supplies that combine both ATX12V and ATX12VO power supplies.

[0004] Referring to FIG. 1, the current ATX12V pinout 21 shows that the outputs of the top row are +3.3V, -12V, GND, PS_ON#, GND, GND, GND, N / A, +5V, +5V, +5V, and GND from left to right, and the outputs of the bottom row are +3.3V, +3.3V, GND, +5V, GND, +5V, GND, PWR_OK, +5VSB, +12V, +12V, and +3.3V from left to right. The ATX12V pinout 21 is a known technology, so a detailed description will be omitted here. The ATX12V pinout 21 has 24 output interfaces.

[0005] Referring to FIG. 2, the pinout 22 of the current ATX12VO is shown, and the outputs of the top row are, from left to right, PWR_OK, +12VSB, +12V, and +12V with Sense, respectively, and the outputs of the bottom row are, from left to right, PS_ON#, GND, GND, GND, GND, and I_PSU%, respectively. The pinout 22 of the ATX12VO is a known technology, so a detailed description will be omitted here. The pinout 22 of the ATX12VO has 10 output interfaces.

[0006] ATX12V and ATX12VO have significant differences in circuit design, interface design, wiring design, standby voltage, etc., so when integrating ATX12V and ATX12VO into the same power supply, you will encounter the following problems:

[0007] 1. The circuit design is complicated.

[0008] ATX12V and ATX12VO use two completely different circuit designs. The standby voltage of ATX12V is +5VDC, while that of ATX12VO is +12VDC. Therefore, integrating two different transformer circuits onto the same circuit board can lead to overly complex circuits and a large volume of power supply.

[0009] 2. There are too many output interfaces.

[0010] The ATX12V pin arrangement 21 has 24 output interfaces, and the ATX12VO pin arrangement 22 has 10 output interfaces. Therefore, if a power supply device supports both ATX12V and ATX12VO power outputs at the same time, the housing must be provided with 34 output interfaces to connect computer equipment of different specifications. This large number of output interfaces occupies a large area of the housing.

[0011] 3. Increased energy consumption.

[0012] Normally, power supplies that support ATX12V and ATX12VO power outputs do not use ATX12V when connecting computer equipment to the ATX12VO output port to supply power, but general power supplies also supply power to the ATX12V circuit, causing internal dissipation in the electronic elements in the circuit, resulting in energy consumption problems.

[0013] Therefore, how to reduce the number of output interfaces of the housing, simplify the internal circuit, and provide a power supply device with energy saving effect is an urgent goal that related engineers should strive for. Summary of the Invention [Problem to be solved by the invention]

DETAILED DESCRIPTION OF THE INVENTION

[0028] The features and technical contents of the related application of the present invention will be clearly presented in the detailed description of two preferred embodiments combined with the following reference drawings. Please note that in describing the present invention in detail, similar elements are designated by the same numbers.

[0029] 3, 4 and 5, there is shown a first preferred embodiment of the intelligent power supply device of the present invention, which includes a power supply unit 31, an output unit 32 and a transmission unit 33.

[0030] The power supply unit 31 includes a first power supply module 311, a second power supply module 312 connected to the first power supply module 311, a switching module 313 provided between the first power supply module 311 and the second power supply module 312, and a detection module 314 connected to the switching module 313.

[0031] The output section 32 includes a common output module 321 connected to the first power supply module 311, a first output module 322 connected to the first power supply module 311, and a second output module 323 connected to the second power supply module 312.

[0032] The transmission section 33 includes a first transmission line group 331 detachably connected to the first output module 322 and the common output module 321, a first plug structure 332 provided at one end of the first transmission line group 331, a second transmission line group 333 detachably connected to the second output module 323 and the common output module 321, and a second plug structure 334 provided at one end of the second transmission line group 333.

[0033] The first output module 322 outputs a first power supply standard together with the common output module 321, and the second output module 323 outputs a second power supply standard together with the common output module 321. In the first preferred embodiment, the first power supply standard is ATX12V and the second power supply standard is ATX12VO, but in actual implementation, the first power supply standard and the second power supply standard may use different power supply standards and should not be limited thereto.

[0034] The first power supply module 311 provides a first power supply standard outputting ATX12V to the first output module 322 and the common output module 321, and the standby voltage of the first power supply module 311 is +5VDC, and the second power supply module 312 provides a second power supply standard outputting ATX12VO to the second output module 323 and the common output module 321, and the standby voltage of the second power supply module 312 is +12VDC. To enable the first power supply module 311 to use the power of the second power supply module 312, a step-down circuit is provided in the first power supply module 311 to first convert +12VDC to +5VDC, and then the first power supply module 311 again converts the +5VDC standby voltage to the first power supply standard of ATX12V. The second power supply module 312 converts the +12VDC standby voltage into the second power supply standard of ATX12VO. Here, the first power supply module 311 does not have a boost circuit, and the +12V voltage is provided to the second power supply module 312, which can further simplify the circuit of the first power supply module 311 and reduce the number of electronic components used, thereby reducing the occupied volume.

[0035] The common output module 321 has a plurality of common output ports, and the outputs of the plurality of common output ports are one power good signal (PWR_OK), two positive 12 volt power supplies (+12V), and ground (GND), respectively. Referring to Table 1 below, in the first preferred embodiment, the common output module 321 has 10 common output ports, and the outputs of the common output ports in the upper row from left to right are PWR_OK, +5VSB, +12V, +12V, and +3.3V, respectively, and the outputs of the common output ports in the lower row from left to right are +3.3V Sense, +5VSB, +5V, +5V, and GND, respectively. In actual implementation, the common output module 321 may only be provided with PWR_OK, +12V, +12V, and GND, or different combinations and arrangements may be used, and therefore should not be limited thereto. Here, the second power supply module 312 is responsible for outputting PWR_OK, +12V, +12V, and GND, while the first power supply module 311 is responsible for outputting the other signals, +3.3V, +5VSB, +5V, and +5V.

[0036] [Table 1]

[0037] The first output module 322 has a plurality of first output ports. Referring to Table 2 below, in the first preferred embodiment, the first output module 322 has 14 first output ports, and the outputs of the first output ports in the upper row from left to right are +3.3V, +3.3V, GND, +5V, GND, +5V, and GND, respectively. The outputs of the first output ports in the lower row from left to right are +3.3V, -12V, GND, PS_ON#, GND, GND, and GND, respectively. In actual implementation, the first output module 322 may use other arrangements and combinations, and should not be limited thereto.

[0038] [Table 2]

[0039] The second output module 323 has a plurality of second output ports. Referring to Table 3 below, in the first preferred embodiment, the second output module 323 has six second output ports, and the outputs of the second output ports in the upper row are +12V with sense, +12VSB, and PS_ON# from left to right, respectively, and the outputs of the second output ports in the lower row are GND, I_PSU%, and GND from left to right, respectively. In actual implementation, the second output module 323 may use other arrangements and combinations, and should not be limited thereto.

[0040] [Table 3]

[0041] The first output module 322 (Table 2) outputs the first power supply standard of ATX12V together with the common output module 321 (Table 1), and the second output module 323 (Table 3) outputs the second power supply standard of ATX12VO together with the common output module 321 (Table 1).

[0042] The switching module 313 disposed between the first power supply module 311 and the second power supply module 312 is a switching circuit, and is controlled by the detection module 314 to form an on or off state. When the switching module 313 is in the on state, the first power supply module 311 provides power to the second power supply module 312; when the switching module 313 is in the off state, the first power supply module 311 cannot supply power to the second power supply module 312.

[0043] The detection module 314 is a type of detection circuit, and is used to detect whether the second output module 323 is in use. Preferably, the detection module 314 is a current detection technology. When the second output module 323 is connected to an electronic device (e.g., a motherboard), the detection module 314 can detect the output current to determine whether the second output module 323 is in use. In actual implementation, the detection module 314 may use other detection technologies, and should not be limited thereto.

[0044] When the detection module 314 detects that the second output module 323 is in use, the detection module 314 controls the switching module 313 to an off state, and the first power supply module 311 receives no power and therefore does not operate. Therefore, the first power supply module 311 cannot output the first power supply standard of ATX12V. Referring to Table 4, in the first preferred embodiment, when the switching module 313 is in an off state, only PWR_OK, +12V, +12V, and GND among the multiple common output ports of the common output module 321 are output to the outside, and no power is output from the other common output ports, and the first output module 322 also does not output power.

[0045] [Table 4]

[0046] When the detection module 314 detects that the second output module 323 is unused, the detection module 314 controls the switching module 313 to an ON state, so that the first power supply module 311 supplies power to the second power supply module 312, and the first power supply module 311 outputs a first power supply standard of ATX12V.

[0047] In the above-mentioned preferred embodiment, when the detection module 314 detects one of the plurality of second output ports, it controls the switching module 313 to an ON state. In actual implementation, when the detection module 314 detects that all of the plurality of second output ports are unused or that some of the plurality of second output ports are unused, it controls the switching module to an ON state, but this should not be limited thereto.

[0048] It is worth mentioning that PWR_OK, +12V, +12V, and GND of the common output module 321 are main common output ports, which can provide either the first power supply standard of ATX12V or the second power supply standard of ATX12VO. Therefore, the number of interfaces of the common output module 321, the first output module 322, and the second output module 323 can be reduced to 30, and the surface area occupied by the housing of the intelligent power supply device can be further reduced.

[0049] 4 again, when the power supply standard of the electronic device (e.g., motherboard) is the first power supply standard of ATX12V, power is transmitted using the first transmission line group 331. One end of the first transmission line group 331 is detachably connected to the first output module 322 and the common output module 321, and the other end of the first transmission line group 331 is provided with the first plug structure 332, which is connected to the electronic device (not shown) and outputs the first power supply standard of ATX12V (see FIG. 1).

[0050] 5, when the power supply standard of the electronic device (e.g., motherboard) is the second power supply standard of ATX12VO, power is transmitted using the second transmission line group 333. One end of the second transmission line group 333 is detachably connected to the second output module 323 and the common output module 321, and the other end of the second transmission line group 333 is provided with the second plug structure 334, which is connected to the electronic device (not shown) and outputs the second power supply standard of ATX12VO (see FIG. 2).

[0051] Referring to FIG. 6, this is the second preferred embodiment of the intelligent power supply device of the present invention. The second preferred embodiment is generally the same as the first preferred embodiment, so the description of the same parts will be omitted. The difference lies in that the transmission part 33 further includes a third transmission line group 335.

[0052] One end of the third transmission line group 335 is detachably connected to the common output module 321, the first output module 322, and the second output module 323, and the other end of the third transmission line group 335 is provided with a third plug structure 336 and a fourth plug structure 337, the third plug structure 336 outputs a first power supply standard of ATX12V (see FIG. 1), and the fourth plug structure 337 outputs a second power supply standard of ATX12VO (see FIG. 2). Here, the common output module 321, the first output module 322, and the second output module 323 may be integrated into one plug structure, which not only reduces the number of interfaces but also the number of plug structures on the housing of the intelligent power supply device. When the power supply standard of the electronic equipment (e.g., motherboard) is the first power supply standard of ATX12V, the third plug structure 336 is used, and when the power supply standard of the electronic equipment (e.g., motherboard) is the second power supply standard of ATX12VO, the fourth plug structure 337 is used.

[0053] As can be seen from the above description, the intelligent power supply device of the present invention certainly has the following advantages:

[0054] 1. The circuit design is simple.

[0055] The first power supply module 311 and the second power supply module 312 are two separate circuits. The first power supply module 311 can use the +5VDC standby voltage of ATX12V, and can also supply the +12V power supply of ATX12V to the second power supply module 312. This further simplifies the circuit structure of the first power supply module 311 and reduces the internal volume occupied by the intelligent power supply device.

[0056] 2. The number of output interfaces is reduced.

[0057] Among the common output module 321, PWR_OK, +12V, +12V, and GND are main common output ports, which can provide either the first power supply standard of ATX12V or the second power supply standard of ATX12VO, so that the number of interfaces of the common output module 321, the first output module 322, and the second output module 323 can be reduced to 30.

[0058] 3. Low energy consumption.

[0059] When the detection module 314 detects that the second output module 323 is in use, the detection module 314 controls the switching module 313 to an off state, so that the first power supply module 311 cannot obtain power and does not output the first power supply standard of ATX12V, and further reduces energy consumption.

[0060] In summary, the PWR_OK, +12V, +12V, and GND of the common output module 321 are main common output ports, which can supply +12V power of ATX12V to the second power supply module 312, thereby further simplifying the circuit structure of the first power supply module 311 and reducing the number of output interfaces. The detection module 314 detects the usage status of the second output module 323. When the intelligent power supply device outputs the second power standard of ATX12VO, it can completely cut off the power supply of the first power supply module 311, thereby not only not outputting the first power standard of ATX12V, but also reducing energy consumption, thereby reliably achieving the objectives of the present invention.

[0061] However, the above description is merely an embodiment of the present invention and should not be construed as limiting the scope of the present invention. All simple equivalent changes and modifications made in accordance with the scope of this utility model application and the contents of the specification are within the scope of the present invention.
