[0016] The terminology used in the implementation section of this application is for the purpose of explaining specific embodiments of this application only, and is not intended to limit this application.

[0017] The terminology used in the embodiments of this application will be explained below.

[0018] Multiphase power modules: A multiphase power module is a power supply architecture that coordinates the phases of multiple parallel power conversion units. It is mainly used to provide efficient and stable power to electronic devices with high power consumption and high dynamic loads. Its core idea is to use phase interleaving technology to stagger the switching sequence of multiple power conversion units, thereby reducing output current ripple, improving conversion efficiency, reducing heat loss, and enhancing transient response capability.

[0019] Power conversion unit: The power conversion unit may include, but is not limited to, DC-DC converters such as buck power supplies.

[0020] Conversion efficiency of the power conversion unit: The conversion efficiency of the power conversion unit is obtained based on the ratio of the output power of the power conversion unit to the input power of the power conversion unit.

[0021] Conversion efficiency of multiphase power modules: When a multiphase power module includes N power conversion units, the conversion efficiency of the multiphase power module is related to the conversion efficiency of each of the N power conversion units.

[0022] Load ratio of power conversion unit: The proportion of the output current of the power conversion unit in the total output current of the multiphase power module.

[0023] Adjustment Module: The adjustment module can adjust the load ratio of the power conversion unit. Furthermore, the adjustment module can serve as the main controller within the power module, controlling the operation of other modules within the power module.

[0024] Generally, in a multiphase power module comprising N power conversion units, the load ratio of each power conversion unit is 1 / N. This balanced load ratio ensures optimal conversion efficiency for the multiphase power module. However, in practical applications, the consistency of manufacturing processes for components within the power conversion units can lead to a decrease in the conversion efficiency of certain units, thus reducing the overall conversion efficiency of the multiphase power module. Therefore, this embodiment adjusts the load ratio of multiple power conversion units within the multiphase power module, increasing the load ratio of power conversion units with higher conversion efficiency and decreasing the load ratio of power conversion units with lower conversion efficiency, thereby improving the overall conversion efficiency of the multiphase power module to some extent.

[0025] The power module, electronic device, and power adjustment method provided in the embodiments of this application are described below with reference to the accompanying drawings.

[0026] In some embodiments of the present application, Figure 1 As shown, the power module 10 provided in this application embodiment may include: a multiphase power module 100, a detection module 200 and an adjustment module 300. The detection module 200 is connected to the adjustment module 300, and the adjustment module 300 is connected to the multiphase power module 100. The multiphase power module 100 includes multiple power conversion units 110. The detection module 200 is used to detect target information of multiple power conversion units 110, and the target information is information related to the conversion efficiency of the power conversion unit 110; The adjustment module 300 is used to adjust the load ratio of at least two power conversion units 110 among the multiple power conversion units 110 according to the target information of the multiple power conversion units 110; Among them, at least two power conversion units 110 include a first power conversion unit and a second power conversion unit. The conversion efficiency of the first power conversion unit is greater than that of the second power conversion unit. The load ratio of the first power conversion unit after adjustment is greater than that of the first power conversion unit before adjustment. The load ratio of the second power conversion unit after adjustment is less than that of the second power conversion unit before adjustment.

[0027] In the multiphase power module 100, the number of power conversion units 110 can be set according to actual needs, and this application does not impose specific restrictions.

[0028] The detection module 200 can detect target information related to the conversion efficiency of multiple power conversion units 110.

[0029] The adjustment module 300 is used to compare the conversion efficiency of multiple power conversion units 110 according to the target information of multiple power conversion units 110; select at least two power conversion units 110 from the multiple power conversion units 110 according to the conversion efficiency order of multiple power conversion units 110, and adjust the load ratio of the selected at least two power conversion units 110, so that the load ratio of the first power conversion unit with higher conversion efficiency in the multiphase power module increases and the load ratio of the second power conversion unit with lower conversion efficiency decreases, thereby improving the conversion efficiency of the multiphase power module to a certain extent.

[0030] In this way, after the detection module 200 detects the target information related to the conversion efficiency of multiple power conversion units 100 in the multiphase power module 100, the adjustment module 300 adjusts the load ratio of at least two power conversion units 110 among the multiple power conversion units 110 according to the target information of the multiple power conversion units. This increases the load ratio of the first power conversion unit with higher conversion efficiency in the multiphase power module and decreases the load ratio of the second power conversion unit with lower conversion efficiency, thereby improving the conversion efficiency of the multiphase power module to a certain extent.

[0031] In some embodiments of this application, in order to improve the power supply quality of the multiphase power module 100, such as Figure 1 As shown, in the multiphase power module 100, multiple power conversion units 110 are connected in parallel, and the switching sequence of the multiple power conversion units 110 is staggered, so that the multiple power conversion units 110 work in phase coordination to provide time-sharing power supply to electronic devices, thereby reducing output current ripple, improving conversion efficiency, reducing heat loss, and enhancing transient response capability.

[0032] In some embodiments of this application, in order to adjust the load ratio of at least two power conversion units 110 among a plurality of power conversion units 110, such as Figure 1 As shown, the adjustment module 300 is connected to multiple power conversion units 110 in the multiphase power module 100. Therefore, the adjustment module 300 can adjust the load ratio of any power conversion unit among the multiple power conversion units 110.

[0033] In some embodiments of the present application, Figure 2As shown, in the multiphase power module 100, at least two power conversion units 110 include a first power conversion unit 1101 and a second power conversion unit 1102. After the detection module 200 detects the first target information of the first power conversion unit 1101 and the second target information of the second power conversion unit 1102, the adjustment module 300 determines, based on the first target information and the second target information, that if the conversion efficiency n1 of the first power conversion unit 1101 is greater than the conversion efficiency n2 of the second power conversion unit 1102, the adjustment module 300 can increase the load ratio of the first power conversion unit 1101, thereby increasing the load ratio of the first power conversion unit with higher conversion efficiency; at the same time, it can decrease the load ratio of the second power conversion unit 1102, thereby reducing the load ratio of the second power conversion unit with lower conversion efficiency.

[0034] For example, taking a multiphase power module 100 including a first power conversion unit 1101 and a second power conversion unit 1102 as an example, the load ratio of the first power conversion unit 1101 before adjustment is 0.5, and the load ratio of the second power conversion unit 1102 before adjustment is 0.5. When the adjustment module 300 determines that the conversion efficiency n1 of the first power conversion unit 1101 is greater than the conversion efficiency n2 of the second power conversion unit 1102, the adjustment module 300 can adjust the load ratio of the first power conversion unit 1101 from 0.5 to 0.7, thereby increasing the load ratio of the first power conversion unit with higher conversion efficiency; at the same time, it adjusts the load ratio of the second power conversion unit 1102 from 0.5 to 0.3, thereby increasing the load ratio of the second power conversion unit 1102 with lower conversion efficiency, thereby improving the conversion efficiency of the multiphase power module 100.

[0035] Furthermore, to further improve the conversion efficiency of the multiphase power module 100, the adjusted load ratio of the first power conversion unit 1101 can be greater than the adjusted load ratio of the second power conversion unit 1102, thereby further improving the conversion efficiency of the multiphase power module 100. For example, the adjusted load ratio of the first power conversion unit 1101 (0.7) is greater than the adjusted load ratio of the second power conversion unit 1102 (0.3), thus ensuring that the load ratio of the more efficient first power conversion unit 1101 is greater than the load ratio of the less efficient first power conversion unit 1101, further improving the conversion efficiency of the multiphase power module 100.

[0036] In practical applications, the adjustment module 300 can adjust the load ratio of at least two power conversion units 110 according to actual needs. Specifically, it can increase the load ratio of at least one power conversion unit with higher conversion efficiency and decrease the load ratio of at least one power conversion unit with lower conversion efficiency. This application does not impose specific limitations on this. An example is given below.

[0037] In some embodiments of the present application, Figure 2 As shown, in the multiphase power module 100, at least two power conversion units 110 further include a third power conversion unit 1103. The conversion efficiency n3 of the third power conversion unit 1103 is greater than the conversion efficiency n1 of the first power conversion unit 1101. The load ratio after adjustment of the third power conversion unit 1103 is greater than the load ratio before adjustment of the third power conversion unit 1103.

[0038] In this case, when it is determined that the conversion efficiency n3 of the third power conversion unit is greater than the conversion efficiency n1 of the first power conversion unit and the conversion efficiency n2 of the second power conversion unit, the adjustment module 300 can increase the load ratio of the third power conversion unit 1103 and the first power conversion unit 1101, while decreasing the load ratio of the second power conversion unit 1102.

[0039] In this way, the embodiments of this application can increase the load ratio of the third power conversion unit 1103 and the first power conversion unit 1102 with higher conversion efficiency, and reduce the load ratio of the second power conversion unit 1102 with lower conversion efficiency, thereby improving the conversion efficiency of the multiphase power module 100.

[0040] In some embodiments of the present application, Figure 3 As shown, in the multiphase power module 100, at least two power conversion units 110 further include a fourth power conversion unit 1104. The conversion efficiency n4 of the fourth power conversion unit 1104 is less than the conversion efficiency n2 of the second power conversion unit. The load ratio after adjustment of the fourth power conversion unit 1104 is less than the load ratio before adjustment of the fourth power conversion unit 1104.

[0041] Wherein, when it is determined that the conversion efficiency n1 of the first power conversion unit > the conversion efficiency n2 of the second power conversion unit > the conversion efficiency n4 of the fourth power conversion unit, the adjustment module 300 can increase the load ratio of the first power conversion unit 1101, while decreasing the load ratio of the second power conversion unit 1102 and the fourth power conversion unit 1104.

[0042] In this way, the embodiment of this application can increase the load ratio of the first power conversion unit 1102 with higher conversion efficiency and reduce the load ratio of the second power conversion unit 1102 and the fourth power conversion unit 1104 with lower conversion efficiency, thereby improving the conversion efficiency of the multiphase power module 100.

[0043] In some embodiments of this application, each power conversion unit may include a controller and a control switch. The control switch may include, but is not limited to, a MOSFET. The controller can implement timing control of the control switch. In this embodiment, an adjustment module 300 can be used to adjust the duty cycle of the PWM (Pulse Width Modulation) signal of the controller in the power conversion unit, thereby changing the on-time of the control switch in the power conversion unit, and thus changing the magnitude of the output current of the power conversion unit, thereby adjusting the load ratio of the power conversion unit. An example is given below.

[0044] The first power conversion unit 1101 includes a first controller U1 and at least one first control switch Q1, with the first controller U1 connected to at least one first control switch Q1 respectively; the second power conversion unit 1102 includes a second controller U2 and at least one second control switch Q2, with the second controller U2 connected to at least one second control switch Q2 respectively; the adjustment module 300 is connected to the first controller U1 and the second controller U2 respectively; The adjustment module 300 is used to adjust the duty cycle of the first signal output by the first controller U1 to at least one first control switch Q1 and the duty cycle of the second signal output by the second controller U2 to at least one second control switch Q2, respectively.

[0045] like Figure 4 As shown, taking a multiphase power module 100 including a first power conversion unit 1101 and a second power conversion unit 1102 as an example, the first power conversion unit 1101 may include a first controller U1 and a plurality of first control switches Q1, and the first controller U1 is connected to the plurality of first control switches Q1 respectively; the second power conversion unit 1102 includes a second controller U2 and a plurality of second control switches Q2, and the second controller is connected to the plurality of second control switches Q2 respectively; the adjustment module 300 is connected to the first controller U1 and the second controller U2 respectively; The adjustment module 300 is used to adjust the duty cycle of the first signal output by the first controller U1 to multiple first control switches Q1 and the duty cycle of the second signal output by the second controller U2 to multiple second control switches Q2, respectively.

[0046] For example, the adjustment module 300 can be used to increase the duty cycle of the first signal output by the first controller U1 to multiple first control switches Q1, thereby making the load ratio of the first power conversion unit 1101 after adjustment greater than the load ratio of the first power conversion unit 1101 before adjustment. For example, the adjustment module 300 is also used to reduce the duty cycle of the second signal output by the second controller U2 to the multiple second control switches Q2, thereby making the load ratio of the second power conversion unit 1102 after adjustment less than the load ratio of the second power conversion unit 1102 before adjustment.

[0047] The first power conversion unit 1101 may further include a first inductor L1, a first capacitor C1 and a third capacitor C3. The first inductor L1 is used to realize energy storage and transfer; the first capacitor C1 is used to filter out high-frequency noise from the input, smooth the input current, and suppress voltage spikes; the third capacitor C3 is used to filter out output ripple, provide transient response and energy storage buffer.

[0048] The second power conversion unit 1102 may further include a second inductor L2, a second capacitor C2 and a fourth capacitor C4. The second inductor L2 is used to realize energy storage and transfer; the second capacitor C2 is used to filter out high-frequency noise from the input, smooth the input current, and suppress voltage spikes; the fourth capacitor C4 is used to filter out output ripple, provide transient response and energy storage buffer.

[0049] In the power conversion unit, both the first and second signals can be PWM signals. The larger the duty cycle of the PWM signal, the longer the control switch controlled by the PWM signal is on, resulting in a larger output current and a larger load ratio for the power conversion unit. Conversely, the smaller the duty cycle of the PWM signal, the shorter the on time of the control switch controlled by the PWM signal, resulting in a smaller output current and a smaller load ratio for the power conversion unit.

[0050] Thus, in this embodiment of the application, the load ratio of the first power conversion unit 1101 can be increased by increasing the duty cycle of the first signal output by the first controller U1 to the multiple first control switches Q1, while the load ratio of the second power conversion unit 1102 can be decreased by decreasing the duty cycle of the second signal output by the second controller U2 to the multiple second control switches Q2.

[0051] The above description illustrates that the adjustment module 300 can compare the conversion efficiencies of multiple power conversion units 110 based on the target information detected by the detection module 200, and select at least two power conversion units 110 from the multiple power conversion units 110 according to the order of their conversion efficiencies, adjusting the load ratio of the selected at least two power conversion units 110. In practical applications, the target information of multiple power conversion units 110 may include the power information of multiple power conversion units 110. Correspondingly, the detection module 200 may include a power detection module for detecting the power information of multiple power conversion units 110, and then, based on the power information of multiple power conversion units 110, quantitatively determine the specific values ​​of the conversion efficiencies of multiple power conversion units 110, thereby determining the order of their conversion efficiencies, and selecting at least two power conversion units 110 according to this order for load ratio adjustment. Alternatively, the target information for the multiple power conversion units 110 may include temperature data of the multiple power conversion units 110. Correspondingly, the detection module 200 may include a temperature detection module for detecting the temperature data of the multiple power conversion units 110. Then, by comparing the temperature data of the multiple power conversion units 110, the order of their conversion efficiencies can be qualitatively analyzed, and at least two power conversion units 110 can be selected in this order for load ratio adjustment. An example is given below.

[0052] In some embodiments of this application, taking a power detection module that includes a detection module for detecting power information of multiple power conversion units as an example, such as... Figure 5 As shown, the detection module 200 may include a power detection module 210; the first end of the power detection module 210 is connected to the input end A of the multiphase power supply module 100, the second end of the power detection module 210 is coupled to the output end B of the multiphase power supply module 100, and the third end of the power detection module 210 is connected to the adjustment module 300; wherein, the power detection module 210 is used to detect the input power and the output power of the target power conversion unit, and the target power conversion unit is any one of the power conversion units 110 in the multiphase power supply module 100; the adjustment module 300 is used to determine the conversion efficiency of the target power conversion unit based on the ratio of the output power of the target power conversion unit to the input power of the target power conversion unit.

[0053] In this way, after the power detection module 210 detects the input power and output power of the target power conversion unit, the adjustment module 300 can quantitatively determine the specific values ​​of the conversion efficiency of multiple power conversion units 110, thereby determining the order of the conversion efficiency of multiple power conversion units 110. At least two power conversion units 110 are selected in this order to adjust the load ratio. For example, the load ratio of the power conversion unit 110 with higher conversion efficiency is increased, thus increasing the load ratio of the power conversion unit with higher conversion efficiency. At the same time, the load ratio of the power conversion unit 110 with lower conversion efficiency is decreased, thus reducing the load ratio of the power conversion unit with lower conversion efficiency, thereby improving the conversion efficiency of the multiphase power module 100.

[0054] In some embodiments of this application, in order to detect the input power and output power of the target power conversion unit, such as Figure 6 As shown, the power detection module 210 may include a first power detection unit 211 and a second power detection unit 212; The first terminal of the first power detection unit 211 is connected to the input terminal V of the power module 10. IN The first power detection unit 211 is coupled to the second end of the first power detection unit 211, which is connected to the input terminal A of the multiphase power supply module 100, and the third end of the first power detection unit 211 is connected to the adjustment module 300. The first end of the second power detection unit 212 is coupled to the output end B of the multiphase power module 100, the second end of the second power detection unit 212 is grounded, and the third end of the second power detection unit 212 is connected to the adjustment module 300. The first power detection unit 211 is used to detect the input power of the target power conversion unit; the second power detection unit 212 is used to detect the output power of the target power conversion unit, which is any one of the power conversion units 110 in the multiphase power module 100.

[0055] The adjustment module 300 is used to drive multiple power conversion units 110 to work in sequence, so that the power detection module 210 detects the input power and output power of each power conversion unit 110 in the multiple power conversion units 110 in sequence.

[0056] In some embodiments of the present application, Figure 7 As shown, the second power detection unit 212 includes a power detection element PW and a resistor element R; the first end of the power detection element PW is connected to the first end of the resistor element R, the second end of the power detection element PW is connected to the second end of the resistor element R, and the third end of the power detection element PW is connected to the adjustment module 300; the first end of the resistor element R is coupled to the output terminal B of the multiphase power supply module 100, and the second end of the resistor element R is grounded.

[0057] Among them, the resistive element R can be a constant resistive load, so that the output terminal V of the power supply module 10... OUT It operates and outputs a constant current.

[0058] For example, taking a multiphase power module 100 including a first power conversion unit 1101 and a second power conversion unit 1102 as an example, the adjustment module 300 is used to drive the first power conversion unit 1101 and the second power conversion unit 1102 to work sequentially. The first power conversion unit 1101 works first, and the current flows from the input terminal V of the power module 10. IN After conversion by the first power conversion unit 1101, the power flows to the resistive element R and remains there for several seconds. The adjustment module 300 then controls the first power detection unit 211 and the power detection element PW to operate simultaneously, detecting the input and output power of the first power conversion unit 1101 and calculating its conversion efficiency n1, where n1 is the ratio of the output power to the input power of the first power conversion unit 1101. Subsequently, the first power conversion unit 1101 stops operating, and the adjustment module 300 drives the second power conversion unit 1102 to start operating, drawing power from the input terminal V of the power module 10. IN After being converted by the second power conversion unit 1102, the power flows to the resistive element R and is maintained for several seconds. The adjustment module 300 controls the first power detection unit 211 and the power detection element PW to work simultaneously, detect the input power and output power of the second power conversion unit 1102, and calculate the conversion efficiency n2 of the second power conversion unit 1102, where n2 is the ratio of the output power to the input power of the second power conversion unit 1102.

[0059] In this way, the first power detection unit 211 and the second power detection unit 212 respectively detect the input power and output power of the target power conversion unit, so that the adjustment module 300 determines the conversion efficiency of the target power conversion unit based on the ratio of the output power of the target power conversion unit to the input power of the target power conversion unit.

[0060] In practical applications, to prevent the resistive element R in the power detection module 210 from affecting the power supply quality of the multiphase power module 100, the power module may also include a switching switch. This switching switch connects the multiphase power module 100 and the power detection module 210. Furthermore, during the adjustment of the load ratio of the power conversion unit 110, the switching switch connects the multiphase power module 100 and the power detection module 210 to achieve the detection of the input power / output power and the calculation of the conversion efficiency of the power conversion unit 110. After the load ratio adjustment of the power conversion unit 110 is completed, the switching switch disconnects the multiphase power module 100 and the power detection module 210 to prevent the resistive element R in the power detection module 210 from affecting the normal operation of the multiphase power module 100. An example is given below: In some embodiments of the present application, Figure 7 As shown, the power module 10 may also include a first switching switch K1 and a second switching switch K2; The input terminal of the first switching switch K1 is connected to the input terminal V of the power module 10. IN The first output terminal of the first switching switch K1 is connected to the input terminal A of the multiphase power module 100, the second output terminal of the first switching switch K1 is connected to the first terminal of the first power detection unit 211, and the control terminal of the first switching switch K1 is connected to the adjustment module 300. The input terminal of the second switching switch K2 is connected to the output terminal B of the multiphase power module 100, and the first output terminal of the second switching switch K2 is connected to the output terminal V of the power module 10. OUT The second output terminal of the second switching switch K2 is connected to the first terminal of the second power detection unit 212, and the control terminal of the second switching switch K2 is connected to the adjustment module 300.

[0061] In this way, by setting a first switching switch K1 and a second switching switch K2 between the multiphase power module 100 and the power detection module 210 to turn the multiphase power module 100 and the power detection module 210 on / off, the resistive element R in the power detection module 210 can be prevented from affecting the normal operation of the multiphase power module 100.

[0062] For example, the power module 10 has a first mode and a second mode. The first mode is a debugging mode, and the second mode is a power supply mode. In the first mode, the input terminal of the first switch K1 is connected to its second output terminal, and the input terminal of the second switch K2 is connected to its second output terminal. In the second mode, the input terminal of the first switch K1 is connected to its first output terminal, and the input terminal of the second switch K2 is connected to its first output terminal.

[0063] In the first mode, the multiphase power supply module 100 and the power detection module 210 are turned on. The power detection module 210 is used to detect the input power and the output power of the target power conversion unit in the first mode.

[0064] In this way, the input power / output power of the power conversion unit 110 is detected and the conversion efficiency is calculated in the first mode.

[0065] In the second mode, the multiphase power module 100 and the power detection module 210 are disconnected. The multiphase power module 100 is used to supply power in the second mode according to the load ratio adjusted by the first power conversion unit 1101 and the load ratio adjusted by the second power conversion unit 1102.

[0066] In this way, after the load ratio adjustment is completed, the multiphase power module 100 and the power detection module 210 are disconnected by switching on the switch in the second mode to avoid the resistor element R in the power detection module 210 from affecting the normal operation of the multiphase power module 100.

[0067] In some embodiments of this application, the detection module includes a temperature detection module for detecting temperature data of multiple power conversion units, as an example. Figure 8 As shown, the detection module may include a temperature detection module 220, which is connected to the adjustment module 300. The temperature detection module 220 is used to detect the temperature data of multiple power conversion units 110. The adjustment module 300 is used to determine the order of the conversion efficiencies of the multiple power conversion units 110 based on the temperature data of the multiple power conversion units 110.

[0068] The target information for the multiple power conversion units 110 may include temperature data of the multiple power conversion units 110. A higher temperature data for a power conversion unit 110 indicates greater heat loss and lower conversion efficiency. Conversely, a lower temperature data indicates less heat loss and higher conversion efficiency. Based on this, after the temperature detection module 220 detects the temperature data of the multiple power conversion units 110, the adjustment module 300 can determine the order of conversion efficiency of the multiple power conversion units 110 based on the temperature data. Then, it selects at least two power conversion units 110 according to their conversion efficiency order to adjust the load ratio, increasing the load ratio of power conversion units with higher conversion efficiency and decreasing the load ratio of power conversion units with lower conversion efficiency in the multiphase power module, thereby improving the conversion efficiency of the multiphase power module to a certain extent.

[0069] In some embodiments of the present application, Figure 8 As shown, the temperature detection module 220 includes multiple temperature detection units 221, which are coupled to the adjustment module 300. The number of multiple temperature detection units 221 in the temperature detection module 220 is the same as the number of multiple power conversion units 110 in the multiphase power supply module 100. One temperature detection unit 221 corresponds to one power conversion unit 110, so one temperature detection unit 221 is used to detect the temperature data of one power conversion unit 110.

[0070] In this way, one temperature detection unit 221 is used to detect the temperature data of one power conversion unit 110, thereby enabling the temperature detection module 220 to detect the temperature data of multiple power conversion units 110.

[0071] In practical applications, the power conversion unit may include components such as capacitors, inductors, MOSFETs, and controllers. The temperature data of the power conversion unit 110 may include, but is not limited to, at least one of the following: temperature data of the capacitor, inductor, MOSFET, and controller. The following explanation uses the temperature data of the power conversion unit 110 including the temperature data of the inductor as an example.

[0072] In some embodiments of this application, taking a multiphase power module 100 including a first power conversion unit 1101 and a second power conversion unit 1102 as an example, such as... Figure 9 As shown, the plurality of temperature detection units 221 include a first temperature detection unit 2211 and a second temperature detection unit 2212; the first power conversion unit 1101 includes a first inductor L1 and the second power conversion unit 1102 includes a second inductor L2; the first temperature detection unit 2211 is arranged adjacent to the first inductor L1 and the second temperature detection unit 2212 is arranged adjacent to the second inductor L2. The first temperature detection unit 2211 is used to detect the first temperature data of the first inductor L1; the second temperature detection unit 2212 is used to detect the second temperature data of the second inductor L2.

[0073] It should be noted that there are inconsistencies in the manufacturing process of inductors in power conversion units. For example, different batches and different ratios of magnetic powder can lead to variations in the core loss of inductors. Core loss is the energy loss caused by the characteristics of the core material when the inductor operates at high frequencies. When there are fluctuations in materials, processes, or testing, it will result in differences in core loss between batches. Core loss consists of hysteresis loss and eddy current loss, both of which are released as heat. Under the same current conditions, inductors with higher core losses generate more heat, which is reflected in lower conversion efficiency of the corresponding power conversion unit.

[0074] When the materials of all inductors in a multiphase power module are identical during the design phase, the load ratio of the first power conversion unit 1101 and the second power conversion unit 1102 can be 0.5:0.5. However, in reality, the core losses of the inductors are different, and the actual heat generation on the inductor surfaces is different. In this case, some embodiments of this application utilize a temperature detection module 220 to detect the temperature data of the first inductor L1 and the second inductor L2 in real time. When the temperature data of the second inductor L2 is greater than that of the first inductor L1, it indicates that the core loss of the second inductor L2 is greater than that of the first inductor L1, and the conversion efficiency n2 of the second power conversion unit 1102 is less than the conversion efficiency n1 of the first power conversion unit 1101. At this time, the adjustment module 300 adjusts the load ratio of the first power conversion unit 1101 and the second power conversion unit 1102 in real time, increasing the load ratio of the first power conversion unit 1101 with higher conversion efficiency and decreasing the load ratio of the second power conversion unit 1102 with lower conversion efficiency, thereby improving the conversion efficiency of the multiphase power module 100 to a certain extent and reducing power loss.

[0075] In some embodiments of the present application, Figure 10 As shown, the temperature detection module 220 may also include a comparator 222. The first input terminal of the comparator 222 is connected to the first temperature detection unit 2211, the second input terminal of the comparator 222 is connected to the second temperature detection unit 2212, and the output terminal of the comparator 222 is connected to the adjustment module 300. The comparator 222 is used to compare the first temperature data and the second temperature data to obtain a comparison result; the adjustment module 300 is used to determine that the conversion efficiency of the first power conversion unit 1101 is greater than the conversion efficiency of the second power conversion unit 1102 when the comparison result indicates that the first temperature data is less than the second temperature data.

[0076] In this way, comparator 222 compares the temperature data of the first inductor L1 and the second inductor L2, and outputs a signal to the adjustment module 300 to adjust the load ratio of the first power conversion unit 1101 and the second power conversion unit 1102 in real time. This balances the temperature of the first inductor L1 and the second inductor L2, controls the load ratio of the first power conversion unit 1101 (which has lower inductor heat generation and higher conversion efficiency) to increase, and the load ratio of the second power conversion unit 1102 (which has higher inductor heat generation and lower conversion efficiency) to decrease. Ultimately, this achieves the purpose of improving the conversion efficiency of the multiphase power module 100 and reducing power loss.

[0077] Furthermore, in practical applications, as electronic devices are used for a longer period of time, the core loss of the inductors in the multiphase power module may change due to the aging and oxidation of the inductors. The above embodiments of this application use real-time temperature data detection to adjust the load ratio and balance the temperature of multiple inductors. This can promptly correct parameters that have changed due to aging, so that the conversion efficiency of the multiphase power module 100 can reach the optimal level.

[0078] Furthermore, based on a concept similar to the power module provided in any of the above embodiments, this application also provides an electronic device including the power module provided in any of the above embodiments.

[0079] like Figure 11 As shown in the figure, this application embodiment also provides an electronic device 1100, including a power module 10.

[0080] It should be noted that the electronic device 1100 provided in this application embodiment includes the power module provided in any of the above embodiments. The specific structure of the power module can be referred to the above description. To avoid repetition, it will not be described again here.

[0081] In the embodiments of this application, the electronic device can be a terminal or other devices besides a terminal. For example, the electronic device can be a smartwatch, mobile phone, tablet computer, laptop computer, PDA, in-vehicle electronic device, mobile internet device (MID), augmented reality (AR) / virtual reality (VR) device, robot, wearable device, ultra-mobile personal computer (UMPC), netbook, or personal digital assistant (PDA), etc. It can also be a server, network attached storage (NAS), personal computer (PC), etc. The embodiments of this application do not specifically limit the scope.

[0082] Furthermore, based on a concept similar to the power module provided in any of the above embodiments, this application also provides a power adjustment method, which is applied to the power module provided in any of the above embodiments.

[0083] Figure 12 This is a flowchart of a power adjustment method provided in an embodiment of this application.

[0084] like Figure 12As shown, this application provides a power adjustment method that is applied to the power module provided in any of the above embodiments. The power adjustment method may include: Step 1210: The detection module detects and obtains target information for multiple power conversion units; the target information is related to the conversion efficiency of the power conversion units. Step 1220: The adjustment module obtains the target information of multiple power conversion units, and adjusts the load ratio of at least two power conversion units among the multiple power conversion units according to the target information of multiple power conversion units; The at least two power conversion units include a first power conversion unit and a second power conversion unit. The conversion efficiency of the first power conversion unit is greater than that of the second power conversion unit. The adjusted load ratio of the first power conversion unit is greater than the unadjusted load ratio of the first power conversion unit. The adjusted load ratio of the second power conversion unit is less than the unadjusted load ratio of the second power conversion unit.

[0085] According to the power adjustment method provided in the embodiments of this application, after the detection module detects the target information of multiple power conversion units in the multiphase power module, the adjustment module adjusts the load ratio of at least two power conversion units in the multiple power conversion units according to the target information of the multiple power conversion units. This increases the load ratio of the first power conversion unit with higher conversion efficiency in the multiphase power module and decreases the load ratio of the second power conversion unit with lower conversion efficiency, thereby improving the conversion efficiency of the multiphase power module to a certain extent.

[0086] Figure 13 This is a flowchart of a power adjustment method provided in an embodiment of this application.

[0087] In some embodiments of this application, a multiphase power module including a first power conversion unit and a second power conversion unit is used as an example, such as... Figure 13 As shown, the power adjustment method provided in this application embodiment may include: Step 1310: Adjust the first and second switching switches by adjusting the module to put the power module into the first mode; In the first mode, the input terminal of the multiphase power module is connected to the first power detection unit 211, and the output terminal of the multiphase power module is connected to the second power detection unit 212.

[0088] Step 1320: In the first mode, the adjustment module controls the operation of the first power conversion unit, obtains the input power and output power of the first power conversion unit detected by the power detection module, and calculates the conversion efficiency n1 of the first power conversion unit; Step 1330: In the first mode, adjust the module to control the operation of the second power conversion unit, obtain the input power and output power of the second power conversion unit detected by the power detection module, and calculate the conversion efficiency n2 of the second power conversion unit; Step 1340: Determine if n1 > n2? If n1 is greater than n2, proceed to step 1350; if n1 is less than n2, proceed to step 1360.

[0089] Step 1350: Adjust the module to increase the load ratio of the first power conversion unit and decrease the load ratio of the second power conversion unit; Step 1360: Adjust the module to lower the load ratio of the first power conversion unit and increase the load ratio of the second power conversion unit.

[0090] In this way, by using a power detection module to measure power, the actual difference in conversion efficiency can be quantitatively determined with high accuracy. This allows for an increase in the load ratio of power conversion units with high conversion efficiency and a decrease in the load ratio of power conversion units with low conversion efficiency, ultimately achieving the goal of improving the conversion efficiency of the multiphase power module and reducing power loss.

[0091] For example, such as Figure 14 As shown, before the load ratio adjustment, the conversion efficiency of the multiphase power module can be referenced to the first curve; after the load ratio adjustment, the conversion efficiency can be referenced to the second curve. Specifically, before the load ratio adjustment, the load ratio of the first power conversion unit and the second power conversion unit can be 0.5:0.5. At this time, the core loss of the second inductor in the second power conversion unit is relatively large, and the conversion efficiency of the second power conversion unit is relatively low, resulting in a lower conversion efficiency of the multiphase power module in some current ranges. However, by using... Figure 13 After the load ratio is adjusted using the power adjustment method shown, the load ratio of the first power conversion unit and the second power conversion unit can be 0.7:0.3. In this case, the load ratio of the first power conversion unit with high conversion efficiency increases, while the load ratio of the second power conversion unit with low conversion efficiency decreases, ultimately achieving the goal of improving the conversion efficiency of the multiphase power module and reducing power loss.

[0092] Furthermore, after step 1350 or step 1360, this embodiment of the application can control the first switching switch and the second switching switch through the adjustment module to enable the power module to enter the second mode. In the second mode, the multiphase power module is controlled to supply power according to the load ratio adjusted by the first power conversion unit and the load ratio adjusted by the second power conversion unit. Thus, after the electronic device performs a load ratio adjustment of the multiphase power module, it can ensure that the multiphase power module operates on the optimal power efficiency curve.

The conversion efficiency of the first power conversion unit is greater than that of the second power conversion unit. The adjusted load ratio of the first power conversion unit is greater than the unadjusted load ratio of the first power conversion unit. The adjusted load ratio of the second power conversion unit is less than the unadjusted load ratio of the second power conversion unit.
