[0043] The following describes the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. The terms used in the implementation method section of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application.

[0044] The embodiments of the present application are described below in conjunction with the accompanying drawings. Those skilled in the art will appreciate that, with the development of technology and the emergence of new scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0045] The terms "first", "second" etc. in the present application are used to distinguish similar objects, and need not be used to describe a specific order or sequential order. It should be understood that the terms used in this way can be interchangeable in appropriate circumstances, and this is only to describe the distinction mode adopted by the objects of the same attributes when describing in the embodiments of the present application. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, so that the process, method, system, product or equipment comprising a series of units need not be limited to those units, but may include other units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0046] In the two-stage power supply scheme of electronic devices, in order to significantly improve energy efficiency and overall system performance, the first stage can use a switched capacitor voltage regulator (SCVR). SCVR can use capacitors (such as CFly capacitors) as energy storage elements for voltage regulation. Compared with traditional inductive buck regulators, capacitors have higher energy storage density, enabling SCVR to achieve more efficient voltage conversion.

[0047] For example, Figure 1 As shown in the figure, the input terminal (vin) of SCVR is connected to the battery (assuming the battery voltage is 8V), and the charging and discharging process is controlled by the internal switch tube (SW). In the charging stage, the battery charges the CFly capacitor through the switch tube; in the discharging stage, the CFly capacitor outputs a proportionally reduced voltage (for example, 4V) to the subsequent power management integrated circuit (PMIC) through the switch tube. This process can efficiently convert the high voltage generated by two or three batteries in series into a stable output at the voltage level of a single battery.

[0048] Although SCVR has significant advantages in terms of efficiency improvement and space saving, it also faces some technical challenges. When starting up or waking up from sleep, the power consumption of the load (such as the CPU) increases rapidly, requiring the power system to provide higher current. If the capacity of the CFly capacitor is insufficient, it may not be able to provide enough charge in a short period of time to replenish the charge consumption caused by the increase in load, resulting in a drop in output voltage. When the fluctuation caused by the drop in output voltage is relatively large, the electric field distribution inside the capacitor will change, causing the physical deformation and vibration of the capacitor. If the frequency of this vibration falls within the human hearing range, a howling sound will be generated.

[0049] Therefore, the present application provides a control method to reduce the noise generated by the power supply solution under specific conditions and improve the user experience.

[0050] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0051] Reference Figure 2 , is a flow chart of a control method provided in Example 1 of the present application, such as Figure 2 As shown, the method may include but is not limited to the following steps:

[0052] Step S101: determine that the electronic device enters a first state, and control a first power path to be turned on; the first power path is used to enable a first voltage conversion component to supply power to a target component of the electronic device.

[0053] In the power supply architecture of the electronic device, there may be multiple power paths, such as a first power path and a second power path. In a first state, the first power path may be enabled, while the second power path remains disconnected. The electronic device may be a computer, a tablet, a mobile phone, or other electronic device.

[0054] The first voltage conversion component can be used to adjust the voltage it receives and output the adjusted voltage to the target component. The voltage received by the first voltage conversion component can come from a battery or a power adapter of the electronic device.

[0055] The first voltage conversion component may include but is not limited to: at least one of a DC-DC converter and a linear regulator (LDO).

[0056] Step S102, determining that the electronic device switches from the first state to the second state, controlling the first power path to be disconnected, and controlling the second power path to be turned on; the second power path is used to enable the second voltage conversion component to power the target component; the second power path generates higher noise in the first state than the first power path generates in the first state.

[0057] The second voltage conversion component can be used to adjust the voltage it receives and output the adjusted voltage to the target component. The voltage received by the second voltage conversion component can come from a battery or a power adapter of the electronic device.

[0058] The second voltage conversion component may be different from the first voltage conversion component. Compared with the first voltage conversion component, the second voltage conversion component may provide a wider and more flexible voltage range.

[0059] The stability of power consumption of the electronic device in the first state (e.g., the boot process, the transition stage from the sleep state to the wake-up state, or the process of executing a high-load application or task during normal operation) is lower than the stability of power consumption in the second state (e.g., the stable operation stage, the execution of low-load tasks, or the standby stage).

[0060] In this embodiment, compared with the first power supply path, the second power supply path may include elements, such as capacitors, that are more likely to generate noise when power consumption is unstable, resulting in the second power supply path generating higher noise in the first state than the first power supply path generating higher noise in the first state, and the noise includes the probability of the generated noise and / or the noise size.

[0061] Alternatively, compared with the first power path, the layout or routing of components in the second power path is not optimized enough, resulting in the second power path generating higher noise than the first power path generating in the first state.

[0062] In this embodiment, when the electronic device enters the first state, the first power path can be enabled first, and the first voltage conversion component (such as a DC-DC converter) can be used to provide power to the target component, which helps to reduce or alleviate the high noise problem generated by the second power path when the power consumption is unstable. Through this strategy, the noise level of the electronic device when the power consumption is unstable can be reduced, thereby improving the user's auditory experience.

[0063] When the electronic device switches from the first state to the second state, the first power path can be disconnected and the second power path can be enabled. In the second state, the noise level generated by the second power path is generally low, which can ensure the user experience. In addition, the second power path can provide a wider and more flexible voltage range, thereby better meeting the power supply requirements of the target component in different power consumption states.

[0064] By intelligently switching the first power path and the second power path, it can be ensured that the electronic device can adopt a relatively better power path for power supply in different states, so as to optimize the use of the electronic device.

[0065] As another optional embodiment of the present application, a control method is provided in Embodiment 2 of the present application. This embodiment is mainly an implementation method for determining that the electronic device enters the first state in Embodiment 1. Determining that the electronic device enters the first state may include but is not limited to one of the following:

[0066] Step S11: If a first target signal is obtained, it is determined that the electronic device enters a first state, and the first target signal indicates that a power-on signal or a wake-up signal is generated.

[0067] In this embodiment, when the user presses the power button of the electronic device or performs a wake-up operation (such as through an input device such as a keyboard or a touch screen), the electronic device can generate a power-on signal or a wake-up signal. According to the power-on signal or the wake-up signal, a first target signal can be generated.

[0068] The processor (eg, EC (embedded processor) or MCU (microprocessor) etc.) can determine that the electronic device enters the first state according to the first target signal, and control the first power path to be turned on.

[0069] In this embodiment, by detecting key signals of the electronic device (such as power-on signals and wake-up signals), it is possible to accurately determine whether the electronic device is about to be or is in a state of unstable power consumption, and the first power supply path can be enabled in time to reduce or alleviate the higher noise problem generated by the second power supply path when the power consumption is unstable.

[0070] Step S12: obtaining a first target parameter, determining that the first target parameter satisfies a set amplitude threshold, and determining that the electronic device enters a first state; the first target parameter represents an amplitude of change in power consumption of the electronic device.

[0071] When an electronic device is operating normally, its power consumption (e.g., parameters such as voltage, current, and power consumption that characterize power consumption) usually fluctuates within a relatively stable range. However, during the boot process, the transition phase from sleep state to wake-up state, etc., parameters such as voltage, current, and power consumption may change significantly.

[0072] The electronic device (eg, CPU) may collect parameters characterizing power consumption in real time or periodically, and determine a variation range of the parameters characterizing power consumption within a period of time to obtain a first target parameter.

[0073] The electronic device can directly transmit the obtained first target parameter to the processor (eg, EC or MCU, etc.) through an internal communication bus or a dedicated interface. This method is simple and direct, and can ensure that the processor obtains accurate power consumption change information in a timely manner.

[0074] In order to achieve more efficient power consumption monitoring and state switching in some cases, a dedicated pin (or signal channel) can be set on the processor. There is a certain proportional relationship between the voltage change of the pin and the first target parameter. As the first target parameter changes (i.e., the increase or decrease in the power consumption change), the voltage of the pin will also change accordingly. The processor can indirectly infer the first target parameter of the processor by monitoring the voltage change of the pin and using the known proportional relationship. This method can provide higher flexibility and response speed in practical applications.

[0075] After obtaining the first target parameter, the processor may determine whether the first target parameter satisfies a set amplitude threshold, and if so, determine that the electronic device enters the first state.

[0076] The amplitude threshold can be set as needed and is not limited in this application.

[0077] In this embodiment, by collecting parameters characterizing power consumption in real time or periodically and determining the amplitude of the change, the power consumption state of the electronic device can be accurately reflected. This accurate monitoring helps the electronic device to enable the first power path in time when the power consumption is unstable, so as to reduce or alleviate the high noise problem generated by the second power path when the power consumption is unstable.

[0078] As another optional embodiment of the present application, a control method is provided for Embodiment 3 of the present application. This embodiment is mainly an implementation method of the target component in Embodiment 1. The target component can be used to assist the first voltage conversion component or the second voltage conversion component to power the load in the electronic device.

[0079] In this embodiment, if Figure 3 As shown, the power supply architecture of the electronic device can adopt a two-level power supply scheme, the first voltage conversion component or the second voltage conversion component can serve as a primary power supply unit, the primary power supply unit can convert the voltage into a voltage level suitable for power supply processing by the secondary power supply unit (i.e., the target component), and the secondary power supply unit can further regulate and distribute the voltage converted by the primary power supply unit to provide stable voltage and current for the load of the electronic device (e.g., CPU).

[0080] It should be noted that Figure 3 As a schematic diagram of the two-level power supply scheme, it does not serve as a limitation of the first power path and the second power path.

[0081] In this embodiment, the target component may include but is not limited to: a power management integrated circuit (PMIC).

[0082] In this embodiment, in the first state, the first voltage conversion component (such as a DC-DC converter) is used to provide power to the target component, which helps to reduce or alleviate the high noise problem generated by the second power path when the power consumption is unstable. In addition, the target component assists the first voltage conversion component to more accurately control the output voltage, more reasonably power the load in the electronic device, and ensure the safety of the load's power consumption.

[0083] In the second state, the second voltage conversion component can efficiently perform voltage conversion and output the converted voltage to the target component. The target component can provide a more sophisticated voltage regulation function. By assisting the second voltage conversion component with the target component, the precise voltage requirements of different loads can be met.

[0084] Of course, in this embodiment, the electronic device may also adopt a primary power supply scheme, in which the target component may include: the load of the electronic device. The first voltage conversion component (e.g., a DC-DC converter) may be used as the only power conversion and regulation unit, directly connected to the target component (e.g., a CPU) to provide the required voltage and current for it.

[0085] As another optional embodiment of the present application, a control method is provided in Embodiment 4 of the present application. This embodiment is mainly an implementation method for obtaining the first target parameter in Embodiment 3. Obtaining the first target parameter may include but is not limited to at least one of the following:

[0086] Step S21: Obtain load parameters of a target component of the electronic device.

[0087] The load parameters may be used to characterize the power required by the load connected to the target component. For example, the load parameters may include but are not limited to key indicators such as voltage, current, and power.

[0088] In electronic devices, changes in the power demand of loads (such as CPUs, GPUs, etc.) are one of the main reasons for unstable power consumption. By monitoring load parameters (such as voltage, current, power, etc.), it is possible to accurately determine whether the electronic device is about to enter a state of unstable power consumption (i.e., the first state). When the change amplitude of the load parameter meets the set amplitude threshold, it can be determined that the electronic device has entered the first state, so that the first power path is enabled in time to reduce or alleviate the higher noise problem generated by the second power path when the power consumption is unstable.

[0089] For example, the load connected to the target component may include a CPU. The load parameters of the CPU may include its operating voltage (such as 1.2V, 1.5V, etc.), operating current (such as 2A, 3A, etc.) and power requirements (such as power consumption upper limit of 6W, 8W, etc.). When the CPU performs high-load tasks (such as running large games or video rendering), its current and power requirements will increase significantly, while the voltage demand may remain relatively stable or fluctuate within a certain range. By monitoring the load parameters of the CPU in real time, it is possible to accurately determine whether the electronic device has entered the first state. When the electronic device enters the first state, the first power path can be enabled in time to reduce or alleviate the problem of higher noise generated by the second power path when the power consumption is unstable.

[0090] Step S22: Obtain system operating parameters of the electronic device.

[0091] The system operating parameters may be used to characterize the operating status of the electronic device.

[0092] In this embodiment, the system operation parameters may be collected through hardware sensors and / or API interfaces. The system operation parameters may include but are not limited to: CPU usage, memory occupancy, disk read and write speed, network throughput, etc.

[0093] In this embodiment, the change of the system operation parameters can indirectly reflect the change of the power demand of the load and the power consumption stability of the electronic device. By monitoring the system operation parameters, it is possible to more accurately determine whether the electronic device is about to enter a state of unstable power consumption. When the change amplitude of the system operation parameters meets the set amplitude threshold, it can also be determined that the electronic device enters the first state, and the first power path can be enabled in time to reduce or alleviate the high noise problem generated by the second power path when the power consumption is unstable.

[0094] As another optional embodiment of the present application, a control method is provided in Embodiment 5 of the present application. This embodiment is mainly an implementation method of determining that the electronic device is switched from the first state to the second state in Embodiment 2. Determining that the electronic device is switched from the first state to the second state may include but is not limited to at least one of the following:

[0095] Step S31: If the timing duration meets a set duration threshold, it is determined that the electronic device is switched from the first state to the second state.

[0096] In this embodiment, the processor may start timing when the first target signal is obtained. At the current moment, the timing duration is obtained, that is, the timing duration is the duration from when the first target signal is obtained to the current moment.

[0097] If the timing duration meets the set duration threshold, it can be determined that the electronic device has transitioned from a first state with unstable power consumption to a relatively stable second state.

[0098] In this embodiment, historical data (such as historical data that can reflect power consumption) can be collected and statistically analyzed to determine the average time or typical time required for the electronic device to transition from a first state in which power consumption is unstable to a second state in which power consumption is relatively stable. The set duration threshold can be determined based on the average time or typical time.

[0099] In this embodiment, by comparing the timing duration and setting the duration threshold, it can be ensured that the electronic device has sufficient time to transition from the first state in which power consumption is unstable to the second state in which power consumption is relatively stable, and state switching can be avoided when the electronic device is not yet completely stable, thereby reducing the noise generated by unstable power consumption.

[0100] Step S32: Obtain a second target signal to determine that the electronic device switches from the first state to the second state, wherein the second target signal indicates that at least one of the following items is detected: an operation stage of the electronic device; or an operation content of the electronic device. The operation stage and / or operation content of the electronic device may reflect an improvement in power consumption stability.

[0101] The operation stage of the electronic device may include: displaying the login interface of the operating system; the operating system is fully started and runs stably (eg, entering the user's desktop).

[0102] The operation content of the electronic device may include: transient changes in the boot process, such as the loading of the driver program. Transient changes in the content can reflect the transition of the electronic device from power-on or sleep to stable operation, that is, the power consumption of the electronic device is relatively stable compared to the power consumption during the power-on process or the wake-up process. The operation content of the electronic device can also be the screen content displayed after the electronic device is detected from the beginning of loading the high-power consumption scene to the completion of loading, such as from the start of the game program to the stable output screen, or from the static screen to the dynamic screen output display.

[0103] In this embodiment, when the operation stage and / or operation content of the electronic device is detected, it usually means that the initialization process of the operating system (such as hardware initialization, operating system loading, driver loading) has been completed. When the initialization of the operating system is completed, the power consumption of the electronic device usually tends to be stable. Therefore, when the second target signal is obtained, it can be determined that the electronic device switches from the first state to the second state.

[0104] Step S33, obtaining a second target parameter. If the second target parameter does not meet the set amplitude threshold, determining that the electronic device switches from the first state to the second state; the second target parameter represents the amplitude of the power consumption change of the electronic device.

[0105] When an electronic device operates normally, its power consumption (eg, parameters such as voltage, current, power consumption, etc. that characterize power consumption) usually fluctuates within a relatively stable range.

[0106] The electronic device (eg, CPU) may collect parameters characterizing power consumption in real time or periodically, and determine a variation range of the parameters characterizing power consumption within a period of time to obtain a second target parameter.

[0107] The electronic device can directly transmit the obtained second target parameter to the processor (eg, EC or MCU, etc.) through an internal communication bus or a dedicated interface. This method is simple and direct, and can ensure that the processor obtains accurate power consumption change information in a timely manner.

[0108] In order to achieve more efficient power consumption monitoring and state switching in some cases, a dedicated pin (or signal channel) can be set on the processor. There is a certain proportional relationship between the voltage change of the pin and the second target parameter. As the second target parameter changes (i.e., the increase or decrease in the power consumption change), the voltage of the pin will also change accordingly. The processor can indirectly infer the second target parameter of the processor by monitoring the voltage change of the pin and using the known proportional relationship. This method can provide higher flexibility and response speed in practical applications.

[0109] After obtaining the second target parameter, the processor may determine whether the second target parameter satisfies a set amplitude threshold, and if the second target parameter does not satisfy the set amplitude threshold, determine that the electronic device switches from the first state to the second state.

[0110] In this embodiment, by collecting parameters characterizing power consumption in real time or periodically and determining the variation range thereof, the power consumption state of the electronic device can be accurately reflected. Such accurate monitoring helps the electronic device to reliably switch from the first state to the second state when the power consumption is stable, thereby better meeting the power supply requirements of the target component in different power consumption states.

[0111] As another optional embodiment of the present application, a control method is provided for embodiment 6 of the present application. This embodiment is mainly an implementation of the first power path and the second power path in embodiment 1. The first power path may include but is not limited to: the first power path includes: a first voltage conversion component and a switch component; the switch component is used to turn on or off the electrical connection between the first voltage conversion component and the target component;

[0112] The second power supply path includes: a second voltage conversion component; the second voltage conversion component adjusts the voltage received by the second voltage conversion component by using a capacitor as an energy storage element, and outputs the adjusted voltage to the target component.

[0113] The noise generated by the second voltage conversion component in the first state is higher than the noise generated by the first voltage conversion component in the first state.

[0114] The second voltage conversion component may include, but is not limited to, a SCVR or a BUCK circuit. The target component may include, but is not limited to, a plurality of PMICs.

[0115] like Figure 4 As shown, if the power supply architecture of the electronic device adopts a primary power supply solution, the target component is a load such as a CPU. When the electronic device enters the first state, the switch component can conduct the electrical connection between the first voltage conversion component and the target component. In addition, the second voltage conversion component is prohibited from supplying power to the target component. The first voltage conversion component can adjust the voltage from the power adapter and output the adjusted voltage to the load.

[0116] like Figure 5As shown, if the power supply architecture of the electronic device adopts a two-level power supply scheme, the target component (e.g., multiple PMICs) can be used to assist the first voltage conversion component (e.g., 5V or 3.3V DC-DC) or the second voltage conversion component (e.g., SCVR or BUCK circuit) to power the load in the electronic device (e.g., a P-core cluster for processing complex computing tasks, an E-core cluster for providing high-efficiency and low-power computing capabilities, a graphics processing unit, a memory processor, etc.). When the electronic device enters the first state, the switch component can conduct the electrical connection between the first voltage conversion component and the target component. In addition, the second voltage conversion component prohibits powering the target component.

[0117] The first voltage conversion component can convert the voltage from the power adapter (VBUS) or the battery (Battery) into a voltage level suitable for processing by the target component. The target component can adjust and distribute the voltage converted by the first voltage conversion component to provide stable voltage and current for different loads (such as P-core clusters for processing complex computing tasks, E-core clusters for providing high-performance and low-power computing capabilities, graphics processing units, memory processors, etc.).

[0118] When the electronic device switches from the first state to the second state, the switch component can disconnect the electrical connection between the first voltage conversion component and the target component, and the second voltage conversion component can supply power to the target component.

[0119] The second voltage conversion component can convert the voltage from the power adapter into a voltage level suitable for processing by the target component. The target component can adjust and distribute the voltage converted by the second voltage conversion component to provide stable voltage and current for different loads (such as P-core clusters for processing complex computing tasks, E-core clusters for providing high-performance and low-power computing capabilities, graphics processing units, memory processors, etc.).

[0120] In this embodiment, the first power path includes a first voltage conversion component and a switch component, which can be quickly turned on when the electronic device enters the first state, and the first voltage conversion component provides a stable power supply for the target component. Compared with the second voltage conversion component (such as SCVR), the first voltage conversion component (such as DC-DC converter) generates lower noise when the power consumption is unstable, which helps to reduce or alleviate the noise problem when the power consumption is unstable.

[0121] Furthermore, the second voltage conversion component (e.g., SCVR) can use a capacitor as an energy storage element for voltage regulation, and has higher energy storage density and conversion efficiency than a conventional inductive buck regulator, which helps to reduce the energy consumption of the power supply system and improve the overall energy efficiency of the electronic device. Furthermore, when the electronic device switches from the first state to the second state, the second voltage conversion component can provide a wider and more flexible voltage range, providing a stable output voltage for the target component to meet the power supply requirements of the target component in different power consumption states.

[0122] As another optional embodiment of the present application, a control method is provided in Embodiment 7 of the present application. This embodiment is mainly an implementation method of controlling the conduction of the first power path in Embodiment 6. Controlling the conduction of the first power path may include but is not limited to the following steps:

[0123] Step S41, stop sending the first control signal to the second voltage conversion component, and send the second control signal to the switch component to enable the switch component to conduct the electrical connection between the first voltage conversion component and the target component; the first control signal is used to control the second voltage conversion component to supply power to the target component.

[0124] When the electronic device enters the first state, the processor may stop sending the first control signal to the second voltage conversion component (such as SCVR). The first control signal is originally used to instruct the second voltage conversion component to start working and supply power to the target component (such as PMIC). However, in the first state, since it is desired to use the first voltage conversion component (such as DC-DC converter) to supply power first and reduce the generation of noise, the first control signal is temporarily stopped.

[0125] At the same time, the processor can send a second control signal to the switch component. The second control signal is used to control the switch component to close, thereby conducting the electrical connection between the first voltage conversion component and the target component. Once the electrical connection is established, the first voltage conversion component can start working, converting the electrical energy from the power adapter or the battery into a voltage level suitable for the target component to process, and stably supplying power to the target component.

[0126] It should be noted that after the second voltage conversion component receives the first control signal to stop sending, it can automatically enter the standby state or stop working completely, so as to avoid unnecessary noise in the first state. This is because the second voltage conversion component (such as SCVR) usually contains energy storage elements such as capacitors, which may generate noise such as vibration or howling when the power consumption is unstable or the load increases suddenly. In the first state, due to the instability of power consumption, the use of the second voltage conversion component may aggravate this noise problem.

[0127] Therefore, by giving priority to the first voltage conversion component and stopping the operation of the second voltage conversion component, the noise generation can be effectively reduced while ensuring the normal power supply of the electronic device. This control strategy not only improves the overall performance of the electronic device, but also significantly improves the user's auditory experience.

[0128] As another optional embodiment of the present application, refer to Figure 6 , is a flow chart of a control method provided in Example 8 of the present application, such as Figure 6 As shown, the method may include but is not limited to the following steps:

[0129] Step S201: determine that the electronic device enters a first state, and control a first power path to be turned on; the first power path is used to enable a first voltage conversion component to supply power to a target component of the electronic device.

[0130] Step S202: before determining that the electronic device switches from the first state to the second state, determine whether the first voltage conversion component meets the power supply requirement of the target component.

[0131] Determining whether the first voltage conversion component meets the power supply requirement of the target component may include but is not limited to at least one of the following:

[0132] It is detected whether the first voltage conversion component can provide the voltage required by the target component.

[0133] It is detected whether the first voltage conversion component can provide sufficient current to meet the power consumption requirement of the target component.

[0134] If not, execute step S203; if so, execute step S204.

[0135] Step S203: Control the first power path to be disconnected, and control the second power path to be connected.

[0136] Compared with the first voltage conversion component, the second voltage conversion component in the second power supply path has a wider and more flexible voltage output range, and can therefore better meet the diverse power supply requirements of the target components.

[0137] For example, if the first voltage conversion component is a DC-DC converter, the DC voltage value that it can stably output is 5V. However, in the first state, the voltage required by the target component is as high as 6V. At this time, the first voltage conversion component cannot meet the power supply demand of the target component. However, the SCVR in the second power path can provide a higher voltage value, so that it can match the voltage demand of the target component in the first state. Therefore, after detecting that the first voltage conversion component cannot meet the power supply demand, the first power path can be controlled to be disconnected, and the second power path can be turned on at the same time to ensure that the target component can obtain the required voltage, thereby maintaining its normal operation.

[0138] Step S204, determining that the electronic device switches from the first state to the second state, controlling the first power path to be disconnected, and controlling the second power path to be turned on; the second power path is used to enable the second voltage conversion component to power the target component; the second power path generates higher noise in the first state than the first power path generates in the first state.

[0139] In this embodiment, before determining that the electronic device switches from the first state to the second state, if the first voltage conversion component does not meet the power supply demand of the target component, the first power path can be controlled to be disconnected and the second power path can be turned on. Although at this stage, the use of the second power path may generate relatively high noise, the priority is to ensure that the power supply demand of the target component is met, so as to ensure that the target component can obtain a stable and sufficient power supply at each stage, thereby ensuring the overall performance and stability of the electronic device.
