a first power module 101;
a second power module 102 connected in parallel with the first power module 101;
the control module 103 is arranged on a mainboard 201 of the electronic device 200, and the first power module 101 and the second power module 102 are respectively connected with a power utilization module 202 on the mainboard 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 dc power output by the second power module 102 to supply power to the power utilization 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 this embodiment, the electronic device 200 may include a notebook computer, a server, a switch, a smart phone, and other devices.
Here, referring to fig. 1 and 2, comparing the conventional multi-power supply device 11 with the multi-power supply device 100 provided in the present application, the conventional multi-power supply device 11 in fig. 1 must be added with a power board and an IC chip, and the output current ratio of each power supply must be adjusted by the power board and the IC chip together, that is, the internal parameters of each power supply must be controlled by the power board and the IC chip, and power supplies with the same rated power must be used. However, the multi-power-supply apparatus 100 provided in the present application includes the control module 103 disposed on the main board 201 of the electronic device 200, and the control module 103 controls the dc power output by the first power module 101 and the second power module 102, i.e. adjusts the signals output by the first power module 101 and the second power module 102, rather than controlling the internal parameters of each power supply to change the output of the power supply as in the conventional multi-power-supply apparatus 11. It can be seen that, compared with the scheme that a plurality of power supplies are arranged in the conventional multi-power supply device 11, and a power board module and an IC chip module must be additionally arranged, the multi-power supply device 100 provided by the present application only has two parallel power supply modules arranged therein, and the control module is arranged 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, so that the design structure of the multi-power supply device 100 is simplified, and the design cost is reduced.
The device for supplying power by multiple power supplies 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 mainboard 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 mainboard through the control module; the control module is used for controlling the direct current power output by the first power module and the second power module to supply power to the power utilization module based on the access modes of the first power module and the second power module if the first power module and the second power module are accessed to the load current sharing bus of the electronic equipment; the power board and the IC chip are added in the power module in the related technology, the output current ratio of each power supply is adjusted together, the output current ratio after adjustment is used for controlling the output current of each power supply, the design is complex and the cost is high.
An embodiment of the present application provides a multi-power-supply apparatus, and 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, and 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 is arranged on a mainboard 201 of the electronic device 200, and the first power module 101 and the second power module 102 are respectively connected with a power utilization module 202 on the mainboard 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 dc power output by the second power module 102 to supply power to the power utilization 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 opening and multiple types C of power supply ports, when several power supplies are simultaneously connected, there is no standard solution at present because different products have different control logics. The present application provides a detailed description of the technical implementation that the device 100 for supplying power by multiple power sources provided by the present application can ensure that the electronic device system and the power source work normally and can ensure that the rated power of the power source is not exceeded.
In a first achievable application scenario, the control module 103 obtains 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 accessed to a load current sharing bus of the electronic device 200, and in a first access scenario, the control module 103 determines that the access modes represent that the first power module 101 and the second power module 102 are simultaneously accessed to the load current sharing bus, and obtains dc powers output by the first power module 101 and the second power module 102 respectively;
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 first power module 101 and the rated power of the first power module 101 conforms to the difference range, the dc power output by the first power module 101 is reduced, and the power module 202 is powered by the reduced dc power of the first power module 101 and the dc power output by the second power module 102;
the deviation ratio between 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 ratio threshold.
Here, the deviation ratio of the dc power output by the first power module 101 and the second power module 102 can be obtained based on the rated power W1 of the first power module 101, the real-time power P1 when the first power module 101 operates, the rated power W2 of the second power module 102, and the real-time power P2 when the second power module 102 operates. For example, by substituting W1, W2, P1, and P2 into the following equations, the deviation ratio Δ P of the dc power output from the first power module 101 and the second power module 102 can be calculated, and Δ P is 〡 P1/W1-P2/W2 〡.
In an application scenario one, 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 first power module 101 and the rated power of the first power module 101 conforms to the difference range, the multi-power-supply power supply device 100 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; the reduced dc power of the first power module 101 and the dc power output by the second power module 102 are used to supply power to the power module 202. For example, when the control module 103 determines that the access mode indicates that the first power module 101 and the second power module 102 are simultaneously accessed to the load share bus, when the deviation rate Δ P 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 reduce the dc power output by the first power module 101, and ensure that the adjusted Δ P is less than 2%.
In some embodiments, referring to fig. 2, the control module 103 includes a first switch tube 1031 connecting the first power module 101 and the power module 202; the first switch tube 1031 is configured to adjust a switching frequency of the first switch tube 1031 to reduce the dc power output by the first power module 101 if a deviation ratio of the dc power output by the first power module 101 and the second power module 102 exceeds a deviation ratio threshold and a difference between the dc power output by the first power module 101 and a rated power of the first power module 101 conforms to a difference range. Here, the first switching tube 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 switch tube 1032 connecting the second power module 102 and the power consumption module 202; the second switch tube 1032 is configured to adjust a switching frequency of the second switch tube 1032 to reduce the dc power output by the second power module 102 if the deviation ratio of the dc power output by the first power module 101 and the second power module 102 exceeds the deviation ratio 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 conforms to the difference range; here, the second switching tube 1032 may be a second MOSFET.
The deviation ratio between 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 configuration of the device 100 to which power is supplied by multiple power sources in the first scenario is further described, and as shown in fig. 2 and 3, for convenience of description, here, as shown in fig. 3, the first power module 101 is represented by PSU1, the second power module 102 is represented by PSU2, and the first switching tube 1031 is represented by QAThat is, the second switch tube 1032 is QBIs represented by QAAnd QBD with IC chips provided on the electronic apparatus 200, respectivelyAPin, DBPin connection, PSU1 and PSU2 at QAAnd QBUnder the control of (1), power is supplied to the power utilization module 202 on the mainboard 201. After the two PSU1 and PSU2 power supplies are connected simultaneously, the IC chip on the electronic device 200 collects VA+、VAVoltage difference of, and VB+、VBThe voltage difference between the two power sources is detected, and the output powers P1 and P2 of the two power sources are detected. Here, the control module 103 includes an IC chip provided on the electronic apparatus 200. Further, the IC chip disposed on the electronic device 200 compares P1 with P2, and if Δ P is greater than 2% and the dc power output by the PSU1 exceeds 85% of the rated power, the trigger control module 103 will triggerOperation to turn down the DC power output from PSU1, when passing DAControl QAThe Duty cycle of the dc power output by the PSU1 is adjusted, and Δ P after adjustment is ensured to be less than 2%, at this time, the dc power output by the PSU1 and PSU2 is balanced. At this time, referring to fig. 4, the current IA output from the PSU1 is shown in fig. 4 (a), and the current IB output from the PSU2 is shown in fig. 4 (b).
In other scenarios, if the dc power output by the PSU2 exceeds 85% of its rated power, the control module 103 is triggered to adjust the dc power output by the PSU2 low, via DBControl QBThe Duty cycle of the direct current power output by the PSU2 is adjusted, and the adjusted delta P is ensured to be less than 2%, at the moment, the direct current power output by the PSU1 and the direct current power output by the PSU2 are balanced.
In the embodiment of the present application, the rated powers of the first power module 101 and the second power module 102 are different, that is, the multi-power supply apparatus 11 provided by the present application supports parallel connection of power supplies with different powers, and can perform geometric adjustment according to the power of the power supplies.
In a scenario one, both the first power module 101 and the second power module 102 are connected to the host system of the electronic device 200 before starting up, that is, the rated power requirement of the whole device is as follows: PSU1+ PSU 2.

It can be known from the above, the multi-power supply device 11 provided by the present application can directly add the control module 103 to the main board 201 of the electronic device 200, and share the voltage detection, MOSFET and other devices with the original design on the main board 201, without additionally arranging the power board and IC chip in the multi-power supply device 11, directly adopting the common power supply, without the need of special design, simplifying the design structure and design cost of the multi-power supply device 11.
It should be noted that, in the present embodiment, descriptions of the same modules and the same contents as those in the other embodiments may refer to descriptions in the other embodiments, and are not repeated herein.
An embodiment of the present application provides a multi-power-supply apparatus, and 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, and 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 is arranged on a mainboard 201 of the electronic device 200, and the first power module 101 and the second power module 102 are respectively connected with a power utilization module 202 on the mainboard 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 dc power output by the second power module 102 to supply power to the power utilization 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 first power module 101 and the second power module 102 have different power ratings.
In a second achievable application scenario, the control module 103 obtains 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 accessed to the load current sharing bus of the electronic device 200, and in the second access scenario, the control module 103 determines that the access mode represents that the first power module 101 is accessed before the second power module 102 is accessed to the load current sharing bus, controls the dc power output by the first power module 101 to supply power to all power utilization modules included in the power utilization module 202, and controls the dc power output by the second power module 102 to supply power to a part of the power utilization modules in the power utilization module 202. Here, some of the power modules have a higher priority of power usage than the remaining modules in all of the power usage 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 turned on, the first power module 101 is configured to provide a rated power for the host, and after the electronic device 200 is turned on, the first power module 101 supplies power to all power modules of the host system of the electronic device 200. In the process that the first power module 101 supplies power to all power utilization modules of the host system of the electronic device 200, if the second power module 102 is connected to the host system of the electronic device 200, the power supply line of the second power module 102 is designed to supply power to only a part of modules such as a Central Processing Unit (CPU), that is, the part of modules are supplied with power by the first power module 101 before the second power module 102 is connected; after 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 device 100 that supplies power by multiple power sources in the second scenario will be further described, and as shown in fig. 2 and 5, for convenience of description, here, as shown in fig. 5, the first power module 101 is represented by PSU1, the second power module 102 is represented by PSU2, the first switching tube 1031 includes MOS3, MOS4, and MOS5, and the second switching tube 1032 includes MOS 6. If the PSU1 is connected to the host system of the electronic device 200 before the electronic device is powered on, the PSU1 is a standard power supply for the host, and the multi-power-supply power supply apparatus 100 controls the PSU1 to supply power to all power modules of the host system of the electronic device 200 through the MOS3, the MOS4 and the MOS5 after the electronic device 200 is powered on, including the CPU on the motherboard 201 and the remaining modules on the motherboard 201 except the CPU. 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 only to the CPU, and the power supply device 100 controls the PSU2 to supply power only to the CPU through the MOS6, that is, the CPU is supplied with power alone by the PSU1 before the PSU2 is connected; after the PSU2 is connected, the PSU1 and the PSU2 jointly supply power, and therefore the running performance of the CPU is improved.
In the second scenario, the user is allowed to access the PSU2 before the PSU1 power supply is matched with the host of the electronic device 200 to operate normally, and in this scenario, the rated power of the whole device is PSU 1. The circuit is designed on the host motherboard 201, and the PSU1 is set as a fixed rated power supply to supply power to all power utilization modules of the host system. However, the incoming power supply line to the PSU2 is designed solely to supply power only to the CPU, i.e., only the PSU2 power supply line is included in the CPU-supplying part of the PSU 1. 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 the present embodiment, descriptions of the same modules and the same contents as those in the other embodiments may refer to descriptions in the other embodiments, and are not repeated herein.
