DETAILED DESCRIPTION

[0038] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0039] As an important part of electrical equipment, the adapter is responsible for converting the power supply voltage into the working voltage required by the equipment. During the startup of the adapter, the power supply and environment will introduce instantaneous fluctuations and noise, especially when the equipment starts running, the fluctuations of current and power are more significant. These fluctuations will cause large errors in the monitoring data of effective power and current, which may cause damage to the adapter and electrical equipment or unstable startup, and even shorten the service life of the equipment.

[0040] Therefore, how to effectively control power fluctuations during the startup of electrical equipment to ensure that the adapter and the electrical equipment can start stably and avoid power overvoltage or equipment damage is a problem that needs to be solved urgently in current technology.

[0041] In order to improve the startup stability of the adapter and the electrical device, the embodiment of the present application first obtains the power information of the adapter and / or its own power fluctuation data before starting the electrical device. On this basis, the current startup scene is identified according to the acquired parameters, and a startup protection mechanism matching the current startup scene is determined. Finally, the startup of the adapter and the electrical device is controlled based on the startup protection mechanism. Among them, for the startup scene with unqualified power quality, the delayed startup time is calculated according to the power information and power fluctuation data of the adapter, the adapter is started first, and the electrical device is started after the delayed startup time.

[0042] In the embodiment of the present application, on the one hand, for various scenarios that may occur when the electrical device is started, a corresponding appropriate startup protection mechanism is designed respectively, and before starting, the most appropriate startup protection mechanism is matched according to the identified current startup scenario, and then the electrical device is started based on the startup protection mechanism. As a result, the adapter and the electrical device can be started each time based on a suitable startup protection mechanism to reduce the power fluctuation at startup, thereby improving the stability of the electrical device startup process. On the other hand, for the scenario where the power quality is most likely to be unqualified, the electrical device is delayed to start. By delaying the start-up, the startup spikes (i.e., instantaneous current shocks) of the adapter and the electrical device are staggered, so as to avoid the power supply system from bearing the startup shock of two devices at the same time, reduce the fluctuations of instantaneous voltage and current, reduce the pressure of the power supply system, and reduce the back pressure problem. Therefore, the startup process of the device can be carried out during a period when the power fluctuation is small or more stable, thereby reducing the problem of excessive back pressure of the adapter and improving the startup stability.

[0043] In the example of the present application, the execution subject of the adapter control method can be any control device with corresponding processing and control capabilities, and the control device can be the adapter itself or a device other than the adapter. When the execution subject control device is the adapter itself, the adapter can be equipped with a corresponding processor to implement the corresponding steps of the adapter control method and realize the smooth startup of the adapter and the electrical device. When the control device is a device other than the adapter (for example, a third-party electronic device, such as a computer, etc.), the control device can be connected to the adapter to realize the control of the adapter.

[0044] In order to illustrate the technical solutions described in the present application, the following description will be made through specific embodiments, taking the control device being the adapter itself as an example.

[0045] Figure 1 The following is a flowchart of the implementation of the adapter control method provided in the first embodiment of the present application, which is described in detail as follows: S101, obtaining real-time power data and power fluctuation amplitude of the adapter.

[0046] In an embodiment of the present application, real-time collection of adapter power-related data and power supply data can be achieved through sensors and data acquisition modules, and then real-time power data and power supply fluctuation amplitude can be calculated based on the collected power-related data.

[0047] The specific data type included in the power data is not limited here, and any parameter that can reflect the power situation of the adapter can be selected as the power data according to the actual situation. For example, in some optional embodiments, the power data can include any parameter of effective power and power factor.

[0048] The power fluctuation amplitude refers to the instantaneous variation range of current or voltage. If the power fluctuation amplitude is large, the current fluctuation at the startup moment will be more significant, increasing the possibility of current shock when the device starts. Similar to power data, the power fluctuation amplitude can include relevant data of the current fluctuation amplitude and / or the voltage fluctuation amplitude. For example, in some embodiments, the power fluctuation amplitude can include the maximum deviation value of the current within a period of time, and / or the maximum deviation value of the voltage within a period of time.

[0049] As an optional embodiment of the present application, the power data includes effective power and power factor. Accordingly, refer to Figure 2 , S101 specifically includes: S1011, obtaining the real-time voltage effective value, current effective value, and phase angle between the voltage and current of the adapter.

[0050] S1012, determining a power factor based on the phase angle.

[0051] In the embodiment of the present application, the power factor represents the phase relationship between current and voltage. The power factor is an indicator of the phase difference between current and voltage. When the power factor is low, the phase difference between the current waveform and the voltage waveform is large, resulting in an increase in the fluctuation amplitude of the current, thereby increasing the risk of current shock during startup.

[0052] Specifically, let the phase angle between voltage and current be θ , the power factor is , the calculation formula is as follows: =cos(θ) (1) The power factor can also be calculated by calculating the ratio of effective power to total power, that is: =cos(θ)= Pactive / Papparent (2) in, Papparent is Total power.

[0053] S1013, calculating effective power based on the voltage effective value, the current effective value and the power factor.

[0054] In the embodiment of the present application, effective power refers to the actual power obtained by the adapter from the power supply, and its calculation formula is as follows: (3) in, represents the effective power, Indicates the effective value of voltage, Indicates the effective value of the current, Indicates the power factor.

[0055] In the embodiment of the present application, the real-time and true power data of the adapter can be effectively reflected through the effective power and power factor, so as to provide accurate data for subsequent judgments.

[0056] As an optional embodiment of the present application, the power supply fluctuation amplitude includes the current fluctuation amplitude. Accordingly, reference Figure 3 , S101 specifically includes: S1014, obtaining the maximum current value and the minimum current value of the adapter within a recent preset time period.

[0057] S1015, calculating the current fluctuation amplitude according to the maximum current value and the minimum current value.

[0058] In the embodiment of the present application, the current fluctuation amplitude is used to reflect the instantaneous change of the adapter current, which is defined as the maximum deviation of the current within a period of time. Among them, the preset time length is the unit time length for judging the current deviation. The embodiment of the present application does not make too many restrictions on the specific value of the preset time length, and it can be set according to actual needs. For example, in some optional embodiments, it can be set to any value within 20ms to 500ms.

[0059] Based on the maximum current and the minimum current within the preset time, the current fluctuation amplitude can be determined by calculating the difference between the two, that is: (4) in, Indicates the current fluctuation amplitude, is the current value at time t, where t is any time within the preset time. Indicates the maximum current value, Indicates the minimum current value.

[0060] As an optional embodiment of the present application, the power supply fluctuation amplitude includes the voltage fluctuation amplitude. Accordingly, S101 specifically includes: S1016, obtaining a maximum voltage value and a minimum voltage value of the adapter within a recent preset time period.

[0061] S1017, calculating the voltage fluctuation amplitude according to the maximum voltage value and the minimum voltage value.

[0062] In the embodiment of the present application, the voltage fluctuation amplitude is used to reflect the instantaneous change of the adapter voltage, which is defined as the maximum deviation of the voltage within a period of time. Among them, the preset time length is the unit time length for judging the voltage deviation. The embodiment of the present application does not make too many restrictions on the specific value of the preset time length, and it can be set according to actual needs. For example, in some optional embodiments, it can be set to any value within 20ms to 500ms.

[0063] Based on obtaining the maximum voltage value and the minimum voltage value within the preset time, the voltage fluctuation amplitude can be determined by calculating the difference between the two. The principle is consistent with the above formula 3, so it is not repeated here.

[0064] S102: Perform real-time filtering on the acquired power data and power supply fluctuation amplitude.

[0065] Considering that during the startup of the adapter, the power supply and the environment will introduce instantaneous fluctuations and noise, especially when the device just starts to run, the fluctuations of current and power are more significant. These fluctuations will cause large errors in the monitoring data of effective power and current, affecting the stability of the device. That is, in actual applications, interference sources such as environmental fluctuations and power supply noise will cause great interference to the startup process of the adapter, and will also cause great interference to the data of the adapter. Therefore, in order to reduce the impact of instantaneous fluctuations of interference sources and improve the accuracy of monitoring data, after obtaining power data and power supply fluctuation amplitude, the embodiments of the present application will perform real-time filtering on the acquired data, so that the data is more accurate and reliable. Among them, the embodiments of the present application do not make too many restrictions on the specific filtering method used. Preferably, the adaptive filtering method can be used to achieve real-time filtering.

[0066] As an optional embodiment of the present application, the parameters of the adaptive filter can be adjusted by minimizing the estimation error method, and the effective power and current fluctuation amplitude can be filtered according to the adaptive filtering algorithm to reduce the impact of instantaneous environmental fluctuations and power supply noise on the adapter startup process. Specifically, Kalman filtering or minimum mean square error filtering can be used to implement adaptive filtering, where Kalman filtering is a widely used adaptive filtering algorithm, particularly suitable for estimating signals in dynamic systems. It adjusts the filtering parameters in real time through two steps (prediction and update): 1. Prediction: Based on the signal at the previous moment and the known system dynamics, predict the signal value at the current moment.

[0067] 2. Update: Combine the actual measured value and the predicted value, correct the prediction by minimizing the estimation error, and adjust the filter parameters. In this way, the Kalman filter can provide the best signal estimation in a noisy environment, reducing errors and fluctuations.

[0068] The LMS filter minimizes the mean square error between the output signal and the real signal by continuously adjusting the filter weights. In this method, the filter dynamically adjusts its own parameters through a step coefficient (learning rate) to suppress the noise of instantaneous fluctuations, thereby smoothing the changes in the effective power and current fluctuations.

[0069] Through the application of adaptive filtering algorithm, power data (such as effective power) and power fluctuation amplitude are filtered in real time, and the interference of instantaneous environmental fluctuations and power noise on the adapter startup process is effectively reduced. That is, the higher-frequency noise and fluctuation part in the input signal can be suppressed, while the low-frequency effective signal part (that is, long-term trend or stability information) can be retained. It can reduce the impact of instantaneous fluctuations on the data, and the filtered data is more stable and accurate, which can truly reflect the operating status of the adapter and improve the measurement accuracy, thereby improving the reliability of the monitoring system and the stability of the adapter startup process.

[0070] As an embodiment of the present application, when the power data includes a power factor, the power factor may not be filtered in real time. For example, when the power data includes effective power and power factor, the effective power may be filtered in real time without filtering the power factor. That is, it can be understood that in some optional embodiments, the power data and the power supply fluctuation amplitude may not be filtered in real time. In this case, after S101, the related operations of S103 may continue to be performed. It is known that only part of the data is filtered in real time.

[0071] As an optional embodiment of the present application, the power data includes effective power, and the power supply fluctuation amplitude includes current fluctuation amplitude. At this time, the real-time filtering of effective power and current fluctuation amplitude can be performed to reduce the impact of instantaneous fluctuations and improve the accuracy of monitoring data.

[0072] S103, identifying the current startup scene according to the power data and any data in the power supply fluctuation amplitude, and determining the target startup protection mechanism matched by the current startup scene. The startup protection mechanisms matched by different startup scenes are not completely the same.

[0073] In the embodiment of the present application, various scenarios that may occur when the electrical equipment is started are analyzed, and corresponding appropriate startup protection mechanisms are designed respectively. Specifically, in the embodiment of the present application, the startup scenario includes at least two categories of scenarios: power overload scenario and unqualified power quality scenario. Based on this, it is possible to identify whether the adapter may be overloaded according to the power data (i.e., whether it belongs to the power overload scenario), whether the power quality is qualified through the power data (i.e., whether it belongs to the unqualified power quality scenario), whether the power quality is qualified through the power fluctuation amplitude, and whether the power quality is qualified by combining the power data and the power fluctuation amplitude. Therefore, the data in the power data and the power fluctuation amplitude can be selected to perform startup scenario identification, thereby determining the current startup scenario.

[0074] As an embodiment of the present application, the power data includes effective power and power factor. Based on this, the scene recognition operation in S103 includes: The current startup scenario is identified according to at least one parameter of effective power, power factor, and power supply fluctuation amplitude.

[0075] As an optional embodiment of the present application, the power quality unqualified scenario can be subdivided on the basis of the above embodiment, and the power quality unqualified scenario can be further subdivided into the first type of power quality unqualified scenario, the second type of power quality unqualified scenario and the third type of power quality unqualified scenario, reference Figure 4 At this time, the "identifying the current startup scene" in S103 can be refined as follows: S10311: When the effective power exceeds the preset maximum withstand power, it is determined that the current startup scenario is a power overload scenario.

[0076] Effective power refers to the electrical energy absorbed by the adapter from the power supply and converted into useful work. When the effective power is too large (that is, greater than the maximum withstand power), it means that if it is directly started, the adapter may be overloaded, so it belongs to the power overload scenario. Among them, the maximum withstand power needs to be determined according to the specific adapter design parameters.

[0077] S10312: When the power factor is lower than a preset minimum factor threshold, it is determined that the current startup scenario belongs to the first category of unqualified power scenario.

[0078] The power factor is a measure of the phase difference between current and voltage. The power factor is usually between 0 and 1. A power factor close to 1 indicates that the current and voltage are almost the same and the energy transmission efficiency is high. If the power factor is too low (i.e., less than the minimum factor threshold, such as less than 0.9), it may indicate that the power quality is poor, which may affect the working efficiency of the adapter and may increase the loss of the device. The specific size of the minimum factor threshold can be set according to the actual situation and is not limited here.

[0079] S10313: When the power fluctuation amplitude is higher than the corresponding preset maximum fluctuation threshold, it is determined that the current startup scenario belongs to the second type of power failure scenario.

[0080] Among them, the power supply fluctuation amplitude can be the current fluctuation amplitude or the voltage fluctuation amplitude. The power supply fluctuation amplitude refers to the degree of fluctuation of the current waveform or the voltage waveform, which is usually related to factors such as power supply noise and instantaneous voltage fluctuation. When the voltage fluctuation is large, it will cause the electrical equipment to be unable to obtain stable power input when starting. When the current fluctuation amplitude is large, it may cause an unstable current waveform. And when the power supply quality is unqualified, the current fluctuation of the electrical equipment when starting will become more severe, which may cause the instantaneous reverse voltage of the power supply system to be too large.

[0081] In order to ensure stable operation of the equipment, the power supply fluctuation range must be limited. Therefore, when the power supply fluctuation range is higher than the maximum fluctuation threshold, it means that the current power supply is unqualified and needs to be controlled. The specific size of the maximum fluctuation threshold can be set according to the actual situation and is not limited here.

[0082] S10314, calculating a power quality index according to the power factor and the power fluctuation amplitude, and when the power quality index exceeds a preset maximum index threshold, determining that the current startup scenario belongs to the third category of unqualified power scenario.

[0083] The power supply fluctuation amplitude may be a current fluctuation amplitude or a voltage fluctuation amplitude.

[0084] The Power Quality Index (PQI) is a comprehensive indicator for measuring power quality, including factors such as voltage fluctuation, harmonic distortion, and frequency stability. The preset range is dynamically adjusted based on the adapter's load steady-state range and real-time environmental conditions. If the power quality does not reach the preset range, it indicates that power fluctuations may affect the stable startup of the adapter.

[0085] Specifically, the power factor and power fluctuation amplitude can be combined to calculate the power quality index.

[0086] PQI=w 1 ×(1-p f )+w 2 ×CF / CF max (5) in PQI represents the power quality index, p f Indicates the power factor, CF Indicates the power supply fluctuation amplitude, CF maxrepresents the highest fluctuation threshold, w 1 and w 2 is a weight coefficient that reflects the relative importance of power factor and power fluctuation to power quality. PQI The lower the power quality, the better. When the current fluctuation amplitude is used to represent the power fluctuation amplitude, CF Replaced with CFA to indicate the current fluctuation amplitude, CF max Will be replaced by CFA max Indicates the highest current fluctuation threshold. w 1 and w 2 It reflects the relative importance of power factor and current fluctuation to power quality. As an embodiment of the present application, w 1 < w 2 That is, the impact of power fluctuation on power quality is more important.

[0087] As an optional embodiment of the present application, when multiple scene requirements are met at the same time, the current startup scene can belong to multiple scenes at the same time. That is, the identification of the current startup scene is not a multiple-choice 1 process, but one or more scenes are selected from multiple scenes. At this time, the current startup scene belongs to these scenes at the same time, that is, it can be considered that these selected scenes are all the current startup scene.

[0088] As an optional embodiment of the present application, Figure 4 Based on the embodiment of the multiple scenarios shown, a suitable startup protection mechanism can be set for each scenario. Figure 5 At this time, "determining the target startup protection mechanism matching the current startup scenario" in S103 can be refined as follows: S10321: When the current startup scenario is a power overload scenario, the target startup protection mechanism includes: performing overload protection on the adapter.

[0089] S10322: When the current startup scenario belongs to the first type of unqualified power scenario, the target startup protection mechanism includes: correcting the power factor or compensating the power factor.

[0090] Among them, the embodiments of the present application do not impose too many restrictions on the specific power factor correction or compensation strategy, which can be set according to actual needs.

[0091] As an optional embodiment of the present application, in the startup protection mechanism corresponding to the first type of power supply unqualified scenario, while correcting or compensating the power factor, the delayed startup time can also be calculated based on the power data and the power supply fluctuation amplitude.

[0092] S10323, when the current startup scenario belongs to the second type of unqualified power scenario, the target startup protection mechanism includes: performing current stabilization control on the startup current.

[0093] Among them, the embodiment of the present application does not impose too many restrictions on the specific current stabilization control strategy, which can be set according to actual needs.

[0094] As an optional embodiment of the present application, in the startup protection mechanism corresponding to the second type of power supply unqualified scenario, while the startup current is controlled in a current stabilization manner, the delayed startup time can also be calculated based on the power data and the power supply fluctuation amplitude.

[0095] S10324: When the current startup scenario belongs to the third category of unqualified power scenario, the target startup protection mechanism includes: improving power quality or other protection measures.

[0096] The embodiments of the present application do not limit the specific strategies for improving power quality and other protective measures, which can be set according to actual needs. For example, feedback can be given to the user to switch to a new power source.

[0097] As an optional embodiment of the present application, in the startup protection mechanism corresponding to the third type of power supply unqualified scenario, while improving the power supply quality or other protection measures, the delayed startup time can also be calculated based on the power data and the power supply fluctuation amplitude.

[0098] The calculation of the delayed start time in the above steps can be found in Figure 6 Description of the illustrated embodiment.

[0099] S104, controlling the startup of the adapter and the electrical device based on the target startup protection mechanism.

[0100] After determining the target startup protection mechanism corresponding to the current startup scenario, the embodiment of the present application can control the startup of the adapter and the electrical device based on the target startup protection mechanism. For example, for a power overload scenario, the adapter and the electrical device can be started on the basis of overload protection of the adapter. For another example, for a first type of power supply unqualified scenario, the adapter and the electrical device can be started on the basis of correcting the power factor or compensating the power factor. For another example, for a second type of power supply unqualified scenario, the adapter and the electrical device can be started on the basis of current stabilization control of the startup current. And for example, for a third type of power supply unqualified scenario, the adapter and the electrical device are started on the basis of improving the power quality. In addition, if it involves calculating the delayed startup time, when controlling the startup of the adapter and the electrical device, the adapter is controlled to start first, and the electrical device is controlled to start after the delayed startup time.

[0101] In the embodiment of the present application, the most appropriate startup protection mechanism is matched according to the identified current startup scene before startup, and then the electrical device is started based on the startup protection mechanism. As a result, the electrical device can be started each time based on the appropriate startup protection mechanism to reduce power fluctuations during startup, and has strong scene compatibility, which can cope with various possible startup scenes, thereby improving the stability of the startup process of the electrical device.

[0102] Specifically, by real-time monitoring of effective power, power factor and current fluctuation amplitude, combined with the power quality index, it is possible to promptly detect whether the adapter exceeds the maximum power or power quality range, so as to take corresponding startup protection mechanisms, such as protection or compensation measures to start, to ensure the safe and stable operation of the equipment.

[0103] As an optional embodiment of the present application, when multiple scene requirements are met at the same time, the current startup scene can belong to multiple scenes at the same time, and the startup protection mechanism can be executed synchronously. For example, when the effective power in S10311 exceeds the preset maximum withstand power, and the power factor in S10312 is lower than the preset minimum factor threshold, it can be determined that the current startup scene belongs to both the power overload scene and the first category of unqualified power supply scene. At this time, the startup protection mechanisms associated with the two are the target startup protection mechanisms of the current startup scene, that is, the protection mechanisms of the two will run at the same time. On the one hand, the adapter is overloaded based on S10321, and on the other hand, the power factor is corrected or compensated based on S10322. On the basis of these two, the adapter and electrical equipment are started again.

[0104] As an optional embodiment of the present application, in the scenario where the power quality is not qualified, in order to avoid the instantaneous current impact at startup causing excessive reverse voltage of the adapter, the adapter and the electrical device can be started in time-sharing mode to achieve the startup peaks of the adapter and the electrical device staggered, thereby avoiding excessive instantaneous reverse voltage of the power supply, reducing system load, and improving startup stability. Figure 6 , the embodiments of the present application include: S1033, when the current startup scenario is a scenario where the power quality is unqualified, the target startup protection mechanism includes: calculating a delayed startup time according to power data and power fluctuation amplitude.

[0105] It can be understood that any unqualified power supply scenario (including but not limited to the first unqualified power supply scenario, the second unqualified power supply scenario and the third unqualified power supply scenario in the above embodiments) belongs to the unqualified power supply quality scenario. In the embodiment of the present application, the unqualified power supply quality scenario will start the adapter and the electrical device in time-sharing, that is, delay the start of the electrical device.

[0106] In order to avoid excessive reverse pressure on the adapter caused by current shock during startup, the embodiment of the present application adopts the method of adjusting the delayed startup time ( Δt ) to stagger the startup peak of the electrical equipment and the fluctuation of the power supply system. In the embodiment of the present application, the power supply fluctuation amplitude includes the current fluctuation amplitude, and the delayed startup time calculation formula is as follows: Δt=α×(1− )+β×CFA (6) in: Δt is the adjusted delayed start time; is the power factor, which reflects the phase difference between current and voltage. 1− It reflects the degree of power loss when the power factor is low, and also indicates the risk caused by power supply fluctuations. The smaller it is, the longer the startup delay needs to be, so as to give the electrical equipment enough time to start stably when the fluctuation is large. CFA is the current fluctuation amplitude of the power supply, which reflects the degree of power fluctuation. A larger CFA indicates that the power fluctuation is large, and a longer startup delay is also required to smooth the fluctuation and reduce the impact at startup. α and β are adjustment parameters, which respectively control the influence of power factor and power fluctuation amplitude on startup delay.

[0107] The above parameters can be adjusted according to actual needs to optimize the stability of device startup. (1- ): Power Factor Affects the degree of current fluctuation, 1− The larger the value, the more serious the power fluctuation is, and the greater the impact that may be generated during startup. By multiplying the adjustment coefficient α, the startup delay can be appropriately extended to avoid the impact caused by fluctuations. When the power fluctuation is large (i.e., the CFA is large), a longer startup delay is also required so that the device can start gradually and stably to avoid the reverse voltage problem caused by excessive instantaneous current fluctuations. By adjusting the delayed startup time, the startup peaks of the adapter and the electrical equipment are staggered, thereby avoiding excessive instantaneous reverse voltage of the power supply, reducing the system load, and improving startup stability. In practical applications, the values ​​of the adjustment parameters α and β need to be selected according to the actual characteristics of the device and power supply. For example: if the power quality is relatively poor (i.e., the power factor is low and the power fluctuation amplitude is large), it is necessary to appropriately increase α and β, so that the startup delay is longer to ensure that the device starts in a stable environment. If the power supply is relatively stable (i.e., the power factor is high and the power fluctuation amplitude is small), α and β can be appropriately reduced to shorten the startup delay to increase the startup speed of the device. By adjusting the delayed startup time Δt, the impact of unqualified power quality on the startup process of the adapter can be effectively reduced. Specifically, the effects of power factor and power fluctuation amplitude on the delay are controlled by adjusting parameters α and β respectively, ensuring that the device can avoid power fluctuation spikes when starting up, thereby improving the stability of the startup process and avoiding excessive reverse voltage of the adapter.

[0108] During the startup of the adapter and electrical equipment, unqualified power quality (such as voltage fluctuations, poor power factor, etc.) may cause a current surge (i.e., the startup current is too large) when the electrical equipment starts. This current surge will cause the adapter's reverse voltage to be too large, which may cause equipment damage or instability. Therefore, it is very important to avoid these problems by properly adjusting the delayed startup time (Δt).

[0109] S1041, controlling the adapter to start, and controlling the electrical equipment to start after the delayed start time.

[0110] On the basis of determining the delayed start time, when controlling the adapter and the electrical device to start, the adapter is started first, and then the electrical device is started after the delayed start time after the adapter is started. For example, assuming that the delayed start time is 1s, the adapter is controlled to start first, and then the electrical device is controlled to start 1s after the adapter is started.

[0111] By calculating the delayed start time Δt, there are at least the following benefits: 1. Stagger the startup spikes. The startup spikes (i.e., instantaneous current shocks) of the adapter and electrical equipment can be staggered to avoid the power supply system from being subjected to the startup shocks of two devices at the same time, reduce instantaneous voltage and current fluctuations, reduce the pressure on the power supply system, and reduce reverse pressure problems.

[0112] 2. By delaying the startup, the startup process of the device can be carried out during a period when the power fluctuation is smaller or more stable, thereby reducing the problem of excessive reverse voltage of the adapter and improving startup stability.

[0113] 3. By reasonably adjusting the delayed start time, ensure that electrical equipment starts smoothly, and do not cause startup failure or instability in adapters and other devices due to excessive current fluctuations.

[0114] Therefore, the embodiments of the present application can achieve stable startup of the adapter and the electrical device, avoiding power overvoltage or device damage.
