In the embodiment of the present application, the electronic device 200 may include a notebook computer, a server, an exchange, a smart phone, and other devices.
Here, referring to fig. 1 and 2, a comparison of a conventional multi-power supply device 11 with a multi-power supply device 100 according to the present application is described, in which a power board and an IC chip must be added to the conventional multi-power supply device 11 in fig. 1, and the output current ratio of each power supply is adjusted by the power board and the IC chip together, that is, parameters inside each power supply are controlled by the power board and the IC chip, and power supplies with the same rated power must be used.

As can be seen, compared with the conventional multi-power supply device 11 in which a plurality of power supplies are provided, the scheme of providing two modules including a power board and an IC chip is also required, and the multi-power supply device 100 provided by the application is provided with only two parallel power supply modules, and the control module is provided on the main board 201 of the electronic device 200, so that the control of the two power supply modules can be realized to supply power to the power consumption module 202 of the electronic device 200, thus simplifying the design structure of the multi-power supply device 100 and reducing the design cost.
The application provides a multi-power supply device, which comprises a first power supply module; the second power supply module is connected with the first power supply module in parallel; the control module is arranged on a main board of the electronic equipment, and the first power supply module and the second power supply module are respectively connected with the power utilization module on the main board through the control module; the control module is used for controlling the direct current power output by the first power supply module and the second power supply module to supply power to the power utilization module based on the access mode of the first power supply module and the second power supply module if the first power supply module and the second power supply module are connected to the load current sharing bus of the electronic equipment; the application solves the problems that a power board and an IC chip are required to be additionally arranged in a power supply module in the related art, the output current ratio of each power supply is commonly adjusted, the output current of each power supply is controlled by the adjusted output current ratio, and the design is complex and the cost is high.
An embodiment of the present application provides a multi-power supply apparatus, referring to fig. 2, the multi-power supply apparatus 100 may be disposed in a power module of an electronic device 200 to supply power to the electronic device 200, where the multi-power supply apparatus 100 includes:
a first power module 101;
a second power module 102 connected in parallel with the first power module 101;
the control module 103, the control module 103 is arranged on the main board 201 of the electronic equipment 200, and the first power module 101 and the second power module 102 are respectively connected with the power utilization module 202 on the main board 201 through the control module 103;
The control module 103 is configured to control the dc power output by the first power module 101 and the second power module 102 to supply power to the power consumption module 202 based on the access modes of the first power module 101 and the second power module 102 if the first power module 101 and the second power module 102 are connected to the load current sharing bus of the electronic device 200.
Taking the example of the electronic device 200 being provided with multiple types C or one square port and multiple power supply ports of type C, there is currently no standard solution when several power supplies are simultaneously accessed, since different product control logic is different. The present application provides a device 100 for supplying power to multiple power sources through the following application scenario, which can ensure that an electronic device system and a power source work normally and ensure that the rated power of the power source is not exceeded.
In an achievable application scenario one, the control module 103 obtains access modes of the first power supply module 101 and the second power supply module 102 under the condition that the first power supply module 101 and the second power supply module 102 are connected to a load current sharing bus of the electronic device 200, and in the first access scenario, the control module 103 determines that the access modes represent that the first power supply module 101 and the second power supply module 102 are simultaneously connected to the load current sharing bus, and obtains direct current power output by the first power supply module 101 and the second power supply module 102 respectively;
If the deviation rate of the direct current power output by the first power supply module 101 and the second power supply module 102 exceeds the deviation rate threshold, and the difference value between the direct current power output by the first power supply module 101 and the rated power of the first power supply module 101 accords with the difference value range, reducing the direct current power output by the first power supply module 101, and supplying power to the power utilization module 202 through the reduced direct current power of the first power supply module 101 and the direct current power output by the second power supply module 102;
The deviation ratio of the reduced dc power of the first power module 101 and the dc power output by the second power module 102 is less than the deviation ratio threshold.
Here, the deviation ratio of the dc power output by the first power supply module 101 and the second power supply module 102 may be obtained based on the rated power W1 of the first power supply module 101, the real-time power P1 when the first power supply module 101 operates, the rated power W2 of the second power supply module 102, and the real-time power P2 when the second power supply module 102 operates. For example, W1, W2, P1, and P2 are substituted into the following formulas, and the deviation ratio Δp of the dc power output by the first power module 101 and the second power module 102 can be calculated, where Δp= 〡 p1/W1-P2/W2 〡.
In the first application scenario, if the deviation rate of the dc power output by the first power module 101 and the second power module 102 exceeds the deviation rate threshold, and the difference value between the dc power output by the first power module 101 and the rated power of the first power module 101 accords with the difference range, the device 100 powered by multiple power supplies reduces the dc power output by the first power module 101 through the control module 103, and the deviation rate of the reduced dc power of the first power module 101 and the dc power output by the second power module 102 is smaller than the deviation rate threshold; and further, the power consumption module 202 is powered by the reduced direct current power of the first power module 101 and the direct current power output by the second power module 102. In an exemplary embodiment, when the control module 103 determines that the access mode represents that the first power module 101 and the second power module 102 are simultaneously connected to the load current sharing bus, when the deviation rate Δp of the dc power output by the first power module 101 and the second power module 102 is greater than the deviation rate threshold, for example, 2%, and the dc power output by the first power module 101 exceeds 85% of the rated power thereof, the control module 103 is triggered to regulate the dc power output by the first power module 101, and the regulated Δp is ensured to be less than 2%.
In some embodiments, referring to fig. 2, the control module 103 includes a first switching tube 1031 connected to the first power module 101 and the power consumption module 202; the first switching tube 1031 is configured to adjust a switching frequency of the first switching tube 1031 to reduce the dc power output by the first power module 101 if the deviation rate of the dc power output by the first power module 101 and the second power module 102 exceeds a deviation rate threshold, and a difference value between the dc power output by the first power module 101 and the rated power of the first power module 101 accords with a difference range. Here, the first switching transistor 1031 may be a first Metal-Oxide-semiconductor field effect transistor (MOSFET).
In some embodiments, referring to fig. 2, the control module 103 further includes a second switching tube 1032 connecting the second power module 102 and the power module 202; the second switching tube 1032 is configured to adjust the switching frequency of the second switching tube 1032 to reduce the dc power output by the second power module 102 if the deviation rate of the dc power output by the first power module 101 and the second power module 102 exceeds the deviation rate threshold, and the difference between the dc power output by the second power module 102 and the rated power of the second power module 102 accords with the difference range; here, the second switching tube 1032 may be a second MOSFET.
The deviation ratio of the reduced dc power of the second power module 102 and the dc power output by the first power module 101 is smaller than the deviation ratio threshold.
Here, the structure of the multi-power supply apparatus 100 in application scenario one is further described, and as shown in fig. 2 and 3, for convenience of description, here, as shown in fig. 3, the first power supply module 101 is denoted by PSU1, the second power supply module 102 is denoted by PSU2, the first switching transistor 1031 is denoted by Q A, the second switching transistor 1032 is denoted by Q B, Q A and Q B are connected to the D A pin and the D B pin of the IC chip provided on the electronic device 200, respectively, PSU1 and PSU2 power the power module 202 on the motherboard 201 under the control of Q A and Q B. When two power supplies of PSU1 and PSU2 are simultaneously connected, the IC chip disposed on the electronic device 200 collects the voltage difference of V A+、VA and the voltage difference of V B+、VB, so as to detect the output power P1 and P2 of the two power supplies. Here, the control module 103 includes an IC chip provided on the electronic apparatus 200. Further, the IC chip on the electronic device 200 compares P1 with P2, if Δp is greater than 2% at this time and the dc power output by PSU1 exceeds 85% of its rated power, the control module 103 is triggered to reduce the dc power output by PSU1, at this time, Q A is controlled by D A to implement adjustment of Duty cycle of the dc power output by PSU1, and ensure that Δp after adjustment is less than 2%, at this time, the dc power output by PSU1 and PSU2 reach balance. At this time, referring to fig. 4, the current IA output from PSU1 is shown in fig. 4 (a), and the current IB output from PSU2 is shown in fig. 4 (b).
In other scenarios, if the dc power output by PSU2 exceeds 85% of its rated power, the trigger control module 103 controls Q B through D B to adjust the Duty cycle of the dc power output by PSU2, and ensures that Δp after adjustment is less than 2%, at this time, the dc power output by PSU1 and PSU2 reach balance.
In the embodiment of the present application, the rated powers of the first power supply module 101 and the second power supply module 102 are different, that is, the multi-power supply device 11 provided by the present application supports parallel connection of unequal power supplies, and can be adjusted according to the power supply power in an equal ratio.
In the first scenario, the two power sources of the first power source module 101 and the second power source module 102 are both host systems connected to the electronic device 200 before starting up, that is, the rated power requirement of the whole machine is: psu1+psu2. A circuit is designed on a main machine main board 201, the direct current power output by each power supply is detected and compared, a MOSFET is added on the circuit, the MOSFET can be controlled by an IC chip on the main board 201, when 2 power supply powers exceed a set threshold value and are unevenly distributed, namely, the power deviation rate exceeds a preset value, the circuit is started, the MOSFET switching frequency and the duty ratio of the power supply circuit with overhigh power are adjusted, the power is reduced, and finally, the equal power or the power deviation rate meets the requirements of practical application scenes.
As can be seen from the above description, the multi-power supply device 11 provided by the present application can directly add the control module 103 to the motherboard 201 of the electronic device 200, and the motherboard 201 is designed to share the voltage detection and MOSFET devices, without additionally providing a power board and an IC chip in the multi-power supply device 11, and directly adopts a common power supply, without making a special design, thereby simplifying the design structure and design cost of the multi-power supply device 11.
It should be noted that, in this embodiment, the same modules and descriptions of the same content as those in other embodiments may refer to descriptions in other embodiments, and are not repeated here.
An embodiment of the present application provides a multi-power supply apparatus, referring to fig. 2, the multi-power supply apparatus 100 may be disposed in a power module of an electronic device 200 to supply power to the electronic device 200, where the multi-power supply apparatus 100 includes:
a first power module 101;
a second power module 102 connected in parallel with the first power module 101;
the control module 103, the control module 103 is arranged on the main board 201 of the electronic equipment 200, and the first power module 101 and the second power module 102 are respectively connected with the power utilization module 202 on the main board 201 through the control module 103;
The control module 103 is configured to control the dc power output by the first power module 101 and the second power module 102 to supply power to the power consumption module 202 based on the access modes of the first power module 101 and the second power module 102 if the first power module 101 and the second power module 102 are connected to the load current sharing bus of the electronic device 200.
In the embodiment of the present application, the rated power of the first power module 101 is different from the rated power of the second power module 102.
In a second possible application scenario, the control module 103 obtains the access modes of the first power module 101 and the second power module 102 when the first power module 101 and the second power module 102 are connected to the load current sharing bus of the electronic device 200, and in a second access scenario, the control module 103 determines that the access modes represent that the first power module 101 is connected to the second power module 102 before the second power module 102 is connected to the load current sharing bus, controls the direct current power output by the first power module 101 to supply power to all the power utilization modules included in the power utilization module 202, and controls the direct current power output by the second power module 102 to supply power to some modules in the power utilization module 202. Here, some modules have higher priority of electricity use than the rest of all the electricity use modules.
In the second application scenario, for example, if the first power module 101 is connected to the host system of the electronic device 200 before the electronic device 200 is powered on, the first power module 101 is a host standard rated power source, and after the electronic device 200 is powered on, the first power module 101 supplies power to all power consumption modules of the host system of the electronic device 200. In the process that the first power supply module 101 supplies power to all power utilization modules of the host system of the electronic device 200, if the second power supply module 102 is connected to the host system of the electronic device 200, the power supply circuit of the second power supply module 102 is designed to supply power to only part of the modules such as a central processing unit (CPU, central Processing Unit), that is, before the second power supply module 102 is connected, the part of the modules are independently supplied with power by the first power supply module 101; when the second power module 102 is connected, the first power module 101 and the second power module 102 supply power together, so that the operation performance of part of the modules is improved.
Here, the configuration of the multi-power supply device 100 in the second application scenario is further described, and for convenience of description, referring to fig. 2 and 5, the first power supply module 101 is denoted by PSU1, the second power supply module 102 is denoted by PSU2, the first switching transistor 1031 includes MOS3, MOS4, and MOS5, and the second switching transistor 1032 includes MOS6, which are shown in fig. 5. If PSU1 is connected to the host system of electronic device 200 before powering on, PSU1 is a host standard rated power source, and after electronic device 200 is powered on, device 100 powered by multiple power sources controls PSU1 to supply power to all power consumption modules of the host system of electronic device 200, including a CPU on motherboard 201 and the remaining modules except the CPU on motherboard 201, through MOS3, MOS4, and MOS 5. In the process that the PSU1 supplies power to all power utilization modules of the host system of the electronic device 200, if the PSU2 is connected to the host system of the electronic device 200, the PSU2 power supply line is designed to supply power to only the CPU, and the power supply device 100 controls the PSU2 to supply power to only the CPU through the MOS6, that is, the PSU1 supplies power to the CPU independently before the PSU2 is connected; when PSU2 is connected, PSU1 and PSU2 supply power together, so that the running performance of CPU is improved.
In the second scenario, the user is allowed to access PSU2 again under the advanced condition that PSU1 power supply is matched with the host of the electronic device 200, and in the second scenario, the rated power of the whole machine is PSU1. A circuit is designed on the host motherboard 201, and PSU1 is set to a fixed rated power supply to supply power to all power consumption modules of the host system. But the power supply line into which PSU2 is connected is designed solely to supply power to the CPU only, i.e. the PSU2 power supply line is counted only in the part of PSU1 supplying power to the CPU. When the PSU2 is accessed, the power supply capacity of the CPU can be additionally increased, and the running performance of the CPU is improved.
It should be noted that, in this embodiment, the same modules and descriptions of the same content as those in other embodiments may refer to descriptions in other embodiments, and are not repeated here.
