Description

TECHNICAL FIELD

[0001] The present application relates to an intelligent power supply, in particular, an intelligent power supply with ATX12V and ATX12VO power outputs. BACKGROUND

[0002] Power supply is the main equipment in computer. With the progress of science and technology, the specifications of power supply include various types, such as ATX12V, ATX 3.0, and ATX12VO. Among them, ATX12V and ATX12VO are the power supply specifications for motherboards. The old motherboard uses ATX12V power supply, and the new motherboard uses ATX12VO power supply. When there are motherboards with two power supply specifications in the market at the same time, the problem of power supply to different specifications of motherboards must be solved.

[0003] Generally speaking, the simplest solution is to purchase a power supply with the same specifications as the motherboard. There is another solution using a transformer circuit on the market, which converts ATX12VO power supply into ATX12VO power supply (such as TW-M610397). Even manufacturers directly launch power supplies with ATX12V and ATX12VO power supply at the same time.

[0004] Referring to Figure 1 For the current ATX12V pin arrangement 21, the upper row from left to right outputs are +3.3V, -12V, GND, PS_ON#, GND, GND, GND, N / A, +5V, +5V, +5V, and GND, and the lower row from left to right outputs are +3.3V, +3.3V, GND, +5V, GND, +5V, GND, PWR_OK, +5VSB, +12V, +12V, and +3.3V. Since the ATX12V pin arrangement 21 is a known technology, it will not be described in detail here. Among them, the ATX12V pin arrangement 21 has 24 output interfaces.

[0005] Referring to Figure 2 For the current ATX12VO pin arrangement 22, the upper row from left to right outputs are PWR_OK, +12VSB, +12V, +12V, and +12V with Sense, and the lower row from left to right outputs are PS_ON#, GND, GND, GND, and I_PSU%. Since the ATX12VO pin arrangement 22 is a known technology, it will not be described in detail here. Among them, the ATX12VO pin arrangement 22 has 10 output interfaces.

[0006] Because ATX12V and ATX12VO differ significantly in circuit design, interface design, cabling design, and standby voltage specifications, integrating ATX12V and ATX12VO into a single power supply will present the following challenges: I. Complex circuit design: The ATX12V and ATX12VO use two completely different circuit designs and have different standby voltages. The ATX12V has a standby voltage of +5VDC, while the ATX12VO has a standby voltage of +12VDC. If the two different transformer circuits are integrated on the same circuit board, the circuit will be too complex and the power supply will be too bulky.

[0007] II. Too many output interfaces: The ATX12V pin arrangement 21 has 24 output interfaces, and the ATX12VO pin arrangement 22 has 10 output interfaces. If the power supply supports both ATX12V and ATX12VO power outputs, its housing needs to be equipped with 34 output interfaces to provide connections for computer devices of different specifications, resulting in a large number of output interfaces that occupy housing space.

[0008] 3. Increased energy consumption: In general, power supplies that support both ATX12V and ATX12VO power outputs will not use ATX12V when the ATX12VO output interface is connected to the computer device for power supply. However, the power supply will still supply power to the ATX12V circuit. The electronic components in the circuit will generate internal friction, resulting in energy loss. Summary of the Invention

[0009] In view of this, the object of the present invention is to provide an intelligent power supply that can reduce the number of output interfaces on the housing and has a simple internal circuit.

[0010] The intelligent power supply includes a power supply unit and an output unit. The power supply unit includes a first power module and a second power module connected to the first power module.

[0011] The output unit includes a common output module connected to the first power module, a first output module connected to the first power module, and a second output module connected to the second power module. The first output module and the common output module cooperate to output a first power specification, and the second output module and the common output module cooperate to output a second power specification.

[0012] Another technical aspect of the present invention is that the first power supply specification is ATX12V and the second power supply specification is ATX12VO.

[0013] Another technical aspect of the present invention is that the first power supply module described above includes a step-down circuit.

[0014] Another technical aspect of the present invention is that the aforementioned common output module has multiple common output ports, the outputs of which are a power good signal (PWR_OK), two positive 12-volt power supplies (+12V), and a ground (GND).

[0015] Another technical aspect of the present invention is that the power supply unit further includes a switch module disposed between the first power module and the second power module. When the switch module is in the on state, the first power module provides power to the second power module. When the switch module is in the off state, the first power module cannot supply power to the second power module.

[0016] Another technical aspect of the present invention is that the power supply unit further includes a detection module connected to the switch module. The detection module is used to detect whether the second output module is used. When the second output module is used, the switch module is controlled to be in a cut-off state. When the second output module is not used, the switch module is controlled to be in a conduction state.

[0017] Another technical means of the present invention is that the second output module has a plurality of second output ports, and when the detection module detects that one or all of the plurality of second output ports are not used, it controls the switch module to be in an on state.

[0018] Another technical aspect of the present invention is that the aforementioned intelligent power supply further includes a transmission unit, the transmission unit including a first transmission line group, one end of the first transmission line group being detachably connected to the first output module and the common output module, and the other end of the first transmission line group being provided with a first plug structure, the first plug structure outputting the first power specification.

[0019] Another technical aspect of the present invention is that the aforementioned intelligent power supply further includes a transmission unit, the transmission unit including a second transmission line group, one end of the second transmission line group being detachably connected to the second output module and the common output module, and the other end of the second transmission line group being provided with a second plug structure, the second plug structure outputting the second power specification.

[0020] Another technical aspect of the present invention is that the aforementioned intelligent power supply further includes a transmission unit, the transmission unit including a third transmission line group, one end of the third transmission line group being detachably connected to the first output module, the second output module and the common output module, and the other end of the third transmission line group being provided with a third plug structure and a fourth plug structure, the third plug structure outputting the first power specification and the fourth plug structure outputting the second power specification.

[0021] The beneficial effect of the present invention is that the common output module can not only form the first power specification with the first output module, but also form the second power specification with the second output module. This can reduce the number of output interfaces on the outside of the smart power supply. When the detection module detects that the second output module is in use, it controls the switch module to be in the off state to prevent power from entering the second power module, thus achieving the effect of energy saving.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0025] Please see Figure 3 , Figure 4 and Figure 5 This is a first preferred embodiment of an intelligent power supply according to the present invention. The intelligent power supply includes a power supply unit 31, an output unit 32, and a transmission unit 33.

[0026] The power supply unit 31 includes a first power module 311, a second power module 312 connected to the first power module 311, a switch module 313 disposed between the first power module 311 and the second power module 312, and a detection module 314 connected to the switch module 313.

[0027] The output unit 32 includes a common output module 321 connected to the first power module 311, a first output module 322 connected to the first power module 311, and a second output module 323 connected to the second power module 312.

[0028] The transmission unit 33 includes a first transmission line group 331 that is detachably connected to the first output module 322 and the common output module 321, a first plug structure 332 disposed at one end of the first transmission line group 331, a second transmission line group 333 that is detachably connected to the second output module 323 and the common output module 321, and a second plug structure 334 disposed at one end of the second transmission line group 333.

[0029] The first output module 322 cooperates with the common output module 321 to output a first power supply specification, and the second output module 323 cooperates with the common output module 321 to output a second power supply specification. In this first preferred embodiment, the first power supply specification is ATX12V and the second power supply specification is ATX12VO. In actual implementation, other power supply specifications can also be used for the first and second power supplies, and should not be limited thereto.

[0030] The first power module 311 provides the first power specification of ATX12V to the first output module 322 and the common output module 321. The standby voltage of the first power module 311 is +5VDC. The second power module 312 provides the second power specification of ATX12V0 to the second output module 323 and the common output module 321. The standby voltage of the second power module 312 is +12VDC. In order for the first power module 311 to use the power of the second power module 312, the first power module 311 is provided with a step-down circuit to first transform the +12VDC to +5VDC, and then the first power module 311 transforms the +5VDC standby voltage to the first power specification of ATX12V. The second power module 312 transforms the +12VDC standby voltage into the ATX12VO second power specification. The first power module 311 does not have a boost circuit. The +12V voltage is supplied to the second power module 312, which simplifies the circuit of the first power module 311, reduces the number of electronic components used, and reduces the size occupied.

[0031] The common output module 321 has multiple common output ports, the outputs of which are a power good signal (PWR_OK), two +12V power supplies, and a ground (GND). Please refer to Table 1 below. In this first preferred embodiment, the common output module 321 has 10 common output ports. The outputs of the upper row of common output ports from left to right are PWR_OK, +5VSB, +12V, +12V, and +3.3V. The outputs of the lower row of common output ports from left to right are +3.3V Sense, +5VSB, +5V, +5V, and GND. In actual implementation, the common output module 321 may only be configured with PWR_OK, +12V, +12V, and GND, or other combinations and arrangements, and should not be limited thereto. Among them, PWR_OK, +12V, +12V, and GND are output by the second power supply module, while other voltages such as +3.3V, +5VSB, +5V, and +5V are output by the first power supply module.

[0032] Table 1 The first output module 322 has a plurality of first output ports. Please refer to Table 2 below. In the first preferred embodiment, the first output module 322 has 14 first output ports. The outputs of the upper row of first output ports from left to right are +3.3V, +3.3V, GND, +5V, GND, +5V, and GND. The outputs of the lower row of first output ports from left to right are +3.3V, -12V, GND, PS_ON#, GND, GND, and GND. In actual implementation, the first output module 322 can also use other arrangements and combinations, and should not be limited thereto.

[0033] Table 2 The second output module 323 has a plurality of second output ports. Please refer to Table 3 below. In the first preferred embodiment, the second output module 323 has 6 second output ports. The outputs of the upper row of second output ports from left to right are +12Vwith sense, +12VSB, and PS_ON#. The outputs of the lower row of second output ports from left to right are GND, I_PSU%, and GND. In actual implementation, the second output module 323 can also use other arrangements and combinations, and should not be limited thereto.

[0034] Table 3 The first output module 322 (Table 2) works in conjunction with the common output module 321 (Table 1) to output the first power specification of ATX12V, and the second output module 323 (Table 3) works in conjunction with the common output module 321 (Table 1) to output the second power specification of ATX12VO.

[0035] The switch module 313, located between the first power module 311 and the second power module 312, is a switching circuit. The switch module 313 is controlled by the detection module 314 to form an on or off state. When the switch module 313 is in the on state, the first power module 311 provides power to the second power module 312. When the switch module 313 is in the off state, the first power module 311 cannot supply power to the second power module 312.

[0036] The detection module 314 is a detection circuit 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 (such as a motherboard), the detection module 314 can detect the output current and determine that the second output module 323 is in use. In actual implementation, the detection module 314 can also use other detection technologies, and should not be limited thereto.

[0037] When the detection module 314 detects that the second output module 323 is in use, the detection module 314 controls the switch module 313 to be in the off state. The first power module 311 will not receive any power and will not operate. Therefore, the first power module 311 cannot output the first power specification of ATX12V. Please refer to Table 4. In the first preferred embodiment, when the switch module 313 is in the off state, among the multiple common output ports of the common output module 321, only PWR_OK, +12V, +12V, and GND are output to the outside. The other common output ports have no power output. In addition, the first output module 322 will not output power either.

[0038] Table 4 When the detection module 314 detects that the second output module 323 is not in use, the detection module 314 controls the switch module 313 to be in the conducting state, the first power module 311 provides power to the second power module 312, and the first power module 311 outputs the first power specification of ATX12V.

[0039] In this preferred embodiment, when the detection module 314 detects one of the plurality of second output ports, it controls the switch module 313 to be in a conducting state. In actual implementation, the detection module 314 controls the switch module 313 to be in a conducting state when it detects that all of the plurality of second output ports are unused, or when it detects that some of the plurality of second output ports are unused, and should not be limited to this.

[0040] It is worth mentioning that PWR_OK, +12V, +12V, and GND are the main common output ports in the common output module 321. It can provide the first power specification of ATX12V or the second power specification 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 is reduced to 30, and the surface area occupied by the intelligent power supply is further reduced.

[0041] review Figure 4 When the power supply specification of the electronic device (such as the motherboard) is ATX12V, the first transmission line group 331 is used to transmit power. One end of the first transmission line group 331 is detachably connected to the first output module 322 and the common output module 321. 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 in the figure). The first plug structure 332 outputs the first power specification of ATX12V (such as...). Figure 1 ).

[0042] reviewFigure 5 When the power supply specification of the electronic device (such as the motherboard) is the second power supply specification of ATX12VO, the second transmission line group 333 is used to transmit power. One end of the second transmission line group 333 is detachably connected to the second output module 323 and the common output module 321. 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 in the figure). The second plug structure 334 outputs the second power supply specification of ATX12VO (such as...). Figure 2 ).

[0043] Please see Figure 6 This is a second preferred embodiment of an intelligent power supply according to the present invention. The second preferred embodiment is substantially the same as the first preferred embodiment, and the similarities will not be described in detail here. The difference is that the transmission unit 33 further includes a third transmission line group 335.

[0044] 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. 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 an ATX12V first power specification (e.g., Figure 1 The fourth connector structure 337 outputs the second power specification of ATX12VO (such as...). Figure 2 The common output module 321, the first output module 322, and the second output module 323 can be integrated into a single plug structure, thereby reducing not only the number of interfaces but also the number of plug structures on the casing of the smart power supply. When the power supply specification of the electronic device (such as the motherboard) is ATX12V, the third plug structure 336 is used; when the power supply specification of the electronic device (such as the motherboard) is ATX12V0, the fourth plug structure 337 is used.

[0045] As can be seen from the above description, the intelligent power supply of the present invention does indeed have the following effects: I. Simple circuit design: The first power module 311 and the second power module 312 are two separate circuits. The first power module 311 not only uses the +5VDC standby voltage of ATX12V, but also provides the +12V power supply of ATX12V to the second power module 312, which further simplifies the circuit structure of the first power module 311 and reduces the internal volume occupied by the intelligent power supply.

[0046] II. Reduce the number of output interfaces: In the common output module 321, PWR_OK, +12V, +12V, and GND are the main common output ports. It can provide the first power specification of ATX12V or the second power specification 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 is reduced to 30.

[0047] III. Reduce energy consumption: When the detection module 314 detects that the second output module 323 is in use, the detection module 314 controls the switch module 313 to be in the off state, and the first power module 311 will not receive any power. Not only will it not output the first power specification of ATX12V, but it can also reduce energy loss.

[0048] In summary, PWR_OK, +12V, +12V, and GND are the main common output ports in the common output module 321, which allows the +12V power supply of ATX12V to be supplied to the second power module 312. This not only simplifies the circuit structure of the first power module 311 but also reduces the number of output interfaces. The detection module 314 can detect the usage status of the second output module 323. When the intelligent power supply outputs the second power specification of ATX12V0, it completely cuts off the power supply of the first power module 311, not only preventing the output of the first power specification of ATX12V but also reducing energy loss. Therefore, the purpose of this invention can indeed be achieved.

[0049] The above-described embodiments are merely preferred embodiments provided to fully illustrate the present invention, and the scope of protection of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention are all within the scope of protection of the present invention.
