[0056] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present application. However, those skilled in the art should clearly understand that the present application can 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 avoid unnecessary details from interfering with the description of the present application.
[0057] As an important component of electrical equipment, the adapter undertakes the function of converting the power supply voltage into the working voltage required by the equipment. During the startup process of the adapter, the power supply and the environment will introduce instantaneous fluctuations and noises. Especially when the equipment starts to run, the fluctuations of current and power are relatively significant. These fluctuations will cause large errors in the monitoring data of the effective power and current, and further lead to possible damage or unstable startup of the adapter and electrical equipment, and even shorten the service life of the equipment.
[0058] Therefore, how to effectively control the power supply fluctuations during the startup process of electrical equipment, ensure the stable startup of the adapter and electrical equipment, and avoid overvoltage of the power supply or damage to the equipment is an urgent problem to be solved in the current technology.
[0059] To improve the stability of the adapter and the electrical device during startup, in the embodiments of the present application, before starting the electrical device, the power information of the adapter and / or its own power fluctuation data are acquired first. On this basis, according to the acquired parameters, the current startup scenario is identified, and a startup protection mechanism matching the current startup scenario is determined. Finally, based on this startup protection mechanism, the startup of the adapter and the electrical device is controlled. Among them, for the startup scenario with unqualified power quality, the delay startup time is calculated according to the power information of the adapter and the power fluctuation data. First, the adapter is started, and then the electrical device is started after the delay startup time.
[0060] In the embodiments of the present application, on the one hand, for various scenarios that may occur when the electrical device starts up, corresponding appropriate startup protection mechanisms are designed respectively, and the most suitable startup protection mechanism is matched according to the identified current startup scenario before startup, and then the electrical device is started based on this startup protection mechanism. Thus, the adapter and the electrical device can each reduce the power fluctuation during startup by starting based on an appropriate startup protection mechanism, thereby improving the smoothness during the startup process of the electrical device. On the other hand, for the scenario where the power quality is most likely to be unqualified, the electrical device is started with a delay. By delaying the startup, the startup spikes (i.e., instantaneous current surges) of the adapter and the electrical device are staggered, avoiding the power system from bearing the startup impacts of both devices simultaneously, reducing the fluctuations of the instantaneous voltage and current, reducing the pressure on the power system, and reducing the backpressure problem. Therefore, the startup process of the device can be carried out during a period with less or more stable power fluctuations, thereby reducing the problem of excessive backpressure of the adapter and improving the startup stability.
[0061] In the examples of the present application, the execution subject of the adapter control method can be any control device with corresponding processing and control capabilities. This 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 internally provided with a corresponding processor to implement the respective steps of the adapter control method, realizing the smooth startup of the adapter and the electrical device. When the control device is a device other than the adapter (such as a third-party electronic device, such as a computer, etc.), this control device can be connected to the adapter to realize the control of the adapter.
[0062] To illustrate the technical solutions described in the present application, hereinafter, the control device is taken as the adapter itself as an example, and specific embodiments are used for illustration.
[0063] Figure 1 The following shows the implementation flowchart of the adapter control method provided by the first embodiment of the present application, which is described in detail as follows:
[0064] S101, acquire the real-time power data and the power fluctuation amplitude of the adapter.
[0065] In the embodiments of the present application, the real-time collection of adapter power-related data and power supply data can be achieved through sensors and data acquisition modules, and then the real-time power data and power supply fluctuation amplitude can be calculated based on the collected power-related data.
[0066] Among them, the specific data types included in the power data are not limited here too much, and any parameter that can reflect the adapter power situation can be selected as the power data according to the actual situation. For example, in some alternative embodiments, the power data may include any parameter among the active power and the power factor.
[0067] The power supply fluctuation amplitude refers to the instantaneous change range of current or voltage. If the power supply fluctuation amplitude is large, the current fluctuation at the start moment will be more significant, increasing the possibility of current impact when the device starts. Similarly to the power data, the power supply fluctuation amplitude may include relevant data of the current fluctuation amplitude and / or the voltage fluctuation amplitude. For example, in some embodiments, the power supply fluctuation amplitude may 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.
[0068] As an alternative embodiment of the present application, the power data includes the active power and the power factor. Correspondingly, referring to Figure 2 , S101 specifically includes:
[0069] S1011, obtaining the effective voltage value, the effective current value of the adapter in real time, and the phase angle between the voltage and the current.
[0070] S1012, determining the power factor based on the phase angle.
[0071] In the embodiments of the present application, the power factor represents the phase relationship between the current and the voltage. The power factor is an index to measure the phase difference between the current and the 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 current fluctuation amplitude, thereby increasing the risk of current impact during startup.
[0072] Specifically, let the phase angle between the voltage and the current be θ , and the power factor be , the calculation formula is as follows:
[0073] = cos(θ) (1)
[0074] It is also possible to calculate the power factor by calculating the ratio of the active power to the total power, that is:
[0075] = cos(θ) = Pactive / Papparent (2)
[0076] Among them,Papparent is Total power.
[0077] S1013. Calculate the active power based on the effective voltage, effective current, and power factor.
[0078] In the embodiment of the present application, the active power represents the actual power obtained by the adapter from the power supply, and its calculation formula is as follows:
[0079] (3)
[0080] Where, represents the active power, represents the effective value of the voltage, represents the effective value of the current, represents the power factor.
[0081] In the embodiment of the present application, through the active power and the power factor, the real-time and true power data situation of the adapter can be effectively reflected, providing accurate data for subsequent judgments.
[0082] As an optional embodiment of the present application, the power supply fluctuation range includes the current fluctuation range. Correspondingly, referring to Figure 3 , S101 specifically includes:
[0083] S1014. Obtain the maximum current value and the minimum current value of the adapter within the most recent preset time period.
[0084] S1015. Calculate the current fluctuation range according to the maximum current value and the minimum current value.
[0085] In the embodiment of the present application, the current fluctuation range is used to reflect the instantaneous change situation of the adapter current, and is defined as the maximum deviation of the current within a period of time. Among them, the preset time period is the unit time period for judging the current deviation. The embodiment of the present application does not limit the specific value of the preset time period too much and can be set according to actual needs. For example, in some optional embodiments, it can be set to any value within 20 ms to 500 ms.
[0086] On the basis of obtaining the maximum current value and the minimum current value within the preset time period, the difference between the two can be obtained to determine the current fluctuation range, that is:
[0087] (4)
[0088] Where, represents the current fluctuation range, is the current value at time t, where t is any time within the preset time period, represents the maximum current value, represents the minimum current value.
[0089] As an alternative embodiment of the present application, the power fluctuation range includes the voltage fluctuation range. Correspondingly, S101 specifically includes:
[0090] S1016, obtaining the maximum voltage value and the minimum voltage value of the adapter within the most recent preset time period.
[0091] S1017, calculating the voltage fluctuation range based on the maximum voltage value and the minimum voltage value.
[0092] In the embodiment of the present application, the voltage fluctuation range is used to reflect the instantaneous change of the adapter voltage and is defined as the maximum deviation of the voltage within a period of time. Among them, the preset time period is the unit time period for judging the voltage deviation. The embodiment of the present application does not limit the specific value of the preset time period too much and can be set according to actual needs. For example, in some alternative embodiments, it can be set to any value within 20 ms to 500 ms.
[0093] Based on obtaining the maximum voltage value and the minimum voltage value within the preset time period, the difference between the two can be obtained to determine the voltage fluctuation range. Its principle is the same as the above formula 3, so it will not be elaborated here.
[0094] S102, performing real-time filtering on the obtained power data and the power fluctuation range.
[0095] Considering that during the startup process of the adapter, the power supply and the environment will introduce instantaneous fluctuations and noises. Especially when the device starts to run, the fluctuations of the current and power are relatively significant. These fluctuations will cause large errors in the monitoring data of the effective power and current, affecting the stability of the device. That is, in practical applications, interference sources such as environmental fluctuations and power supply noises 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 influence of the instantaneous fluctuations of the interference sources and improve the accuracy of the monitoring data, in the embodiment of the present application, after obtaining the power data and the power fluctuation range, the obtained data will be subjected to real-time filtering, so that the data is more accurate and reliable. Among them, the embodiment of the present application does not limit the specific filtering method used too much. Preferably, an adaptive filtering method can be selected to achieve real-time filtering.
[0096] As an alternative embodiment of the present application, the parameters of the adaptive filtering can be adjusted by the minimum estimation error method, and the effective power and the current fluctuation range can be filtered according to the adaptive filtering algorithm to reduce the influence of instantaneous environmental fluctuations and power supply noises on the startup process of the adapter. Specifically, Kalman filtering or least mean square error filtering can be used to achieve adaptive filtering. Among them, Kalman filtering is a widely used adaptive filtering algorithm, especially suitable for estimating signals in dynamic systems. It adjusts the filtering parameters in real time through two steps (prediction and update):
[0097] 1. Prediction: Based on the signal at the previous moment and the known system dynamics, predict the signal value at the current moment.
[0098] 2. Update: Combine the actual measured value and the predicted value, and correct the prediction by minimizing the estimation error to adjust the parameters of the filter. In this way, the Kalman filter can provide an optimal signal estimation in a noisy environment, reducing errors and fluctuations.
[0099] The LMS filter minimizes the mean square error between the output signal and the true signal by continuously adjusting the weights of the filter. In this method, the filter dynamically adjusts its own parameters through a step coefficient (learning rate), suppressing the instantaneous fluctuating noise, thereby smoothing the changes in the effective power and current fluctuation amplitudes.
[0100] Through the application of the adaptive filtering algorithm, after the power data (such as effective power) and the power supply fluctuation amplitude are filtered in real time, the interference of instantaneous environmental fluctuations and power supply noise on the adapter startup process is effectively reduced. That is, the high-frequency noise and fluctuation parts in the input signal can be suppressed, while the low-frequency effective signal parts (i.e., 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 state of the adapter, improve the measurement accuracy, and thus improve the reliability of the monitoring system and the stability of the adapter startup process.
[0101] As an embodiment of the present application, when the power data includes the power factor, the power factor may not be filtered in real time. For example, when the power data includes the effective power and the power factor, the effective power among them can be filtered in real time while the power factor is not filtered. That is, it can be understood that in some alternative embodiments, the power data and the power supply fluctuation amplitude may not be filtered in real time either. At this time, after S101, the relevant operations of S103 can be continued. It is known that only some of the data are filtered in real time.
[0102] As an alternative embodiment of the present application, the power data includes the effective power, and the power supply fluctuation amplitude includes the current fluctuation amplitude. At this time, by filtering the effective power and the current fluctuation amplitude in real time, the influence of instantaneous fluctuations can be reduced, and the accuracy of the monitoring data can be improved.
[0103] S103. According to any data in the power data and the power supply fluctuation amplitude, identify the current startup scenario, and determine the target startup protection mechanism that matches the current startup scenario. Among them, the startup protection mechanisms matched by different startup scenarios are not completely the same.
[0104] In the embodiments of the present application, various scenarios that may occur when an electrical device starts up are analyzed, and corresponding appropriate start-up protection mechanisms are designed respectively. Specifically, in the embodiments of the present application, the start-up scenarios at least include two major categories of scenarios: power overload scenarios and power quality unqualified scenarios. Based on this, it is possible to identify whether an adapter may be in an overload scenario (i.e., whether it belongs to a power overload scenario) according to power data, identify whether the power quality is qualified (i.e., whether it belongs to a power quality unqualified scenario) through power data, identify whether the power quality is qualified through the power fluctuation amplitude, and identify whether the power quality is qualified by combining power data and power fluctuation amplitude, etc. Therefore, data in either power data or power fluctuation amplitude can be selected to identify the start-up scenario, so as to determine the current start-up scenario.
[0105] As an embodiment of the present application, the power data includes active power and power factor. Based on this, the operations of scenario identification in S103 include:
[0106] Identify the current start-up scenario according to at least one parameter among the active power, power factor, and power fluctuation amplitude.
[0107] As an optional embodiment of the present application, on the basis of the foregoing embodiment, the power quality unqualified scenario can be further subdivided. The power quality unqualified scenario is further subdivided into a first type of power unqualified scenario, a second type of power unqualified scenario, and a third type of power unqualified scenario. Refer to Figure 4 At this time, "identifying the current start-up scenario" in S103 can be refined as:
[0108] S10311, when the active power exceeds the preset maximum tolerable power, it is determined that the current start-up scenario belongs to the power overload scenario.
[0109] The active power refers to the electrical energy absorbed by the adapter from the power supply and converted into useful work. When the active power is too large (i.e., greater than the maximum tolerable power), it indicates that the adapter may be overloaded if directly started at present. Therefore, it belongs to the power overload scenario. Among them, the maximum tolerable power needs to be determined according to the specific adapter design parameters.
[0110] S10312, when the power factor is lower than the preset minimum factor threshold, it is determined that the current start-up scenario belongs to the first type of power unqualified scenario.
[0111] 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.
[0112] 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.
[0113] 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.
[0114] 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.
[0115] 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.
[0116] The power supply fluctuation amplitude may be a current fluctuation amplitude or a voltage fluctuation amplitude.
[0117] 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.
[0118] Specifically, the power factor and power fluctuation amplitude can be combined to calculate the power quality index.
[0119] PQI = w 1 ×(1-p f)+w 2 ×CF / CF max (5)
[0120] Wherein PQI represents the power quality index, p f represents the power factor, CF represents the power supply fluctuation amplitude, CF max represents the highest fluctuation threshold, w 1 and w 2 are weight coefficients, reflecting the relative importance of the power factor and power supply fluctuation to the power quality. Usually, PQI the lower it is, the better the power quality. Among them, when the current fluctuation amplitude is used to characterize the power supply fluctuation amplitude, then CF can be replaced by CFA to represent the current fluctuation amplitude, CF max will be replaced by CFA max represents the highest current fluctuation threshold. At this time w 1 and w 2 reflect the relative importance of the power factor and current fluctuation to the power quality. As an embodiment of the present application, w 1 < w 2 that is, the influence importance of the power supply fluctuation on the power quality is higher.
[0121] As an alternative embodiment of the present application, when multiple scenario requirements are met simultaneously, the current startup scenario can belong to multiple scenarios at the same time. That is, the identification of the current startup scenario is not a process of selecting one from multiple options, but selecting one or more scenarios from multiple scenarios. At this time, the current startup scenario belongs to these scenarios at the same time, that is, it can be considered that these selected scenarios are all the current startup scenarios.
[0122] As an alternative embodiment of the present application, on the basis of the embodiment of multi-scenario refinement shown in Figure 4 , a suitable startup protection mechanism can be set for each scenario. Referring to Figure 5 , at this time, "determining the target startup protection mechanism matching the current startup scenario" in S103 can be refined as:
[0123] S10321, when the current startup scenario belongs to the power overload scenario, the target startup protection mechanism includes: performing overload protection on the adapter.
[0124] S10322, when the current startup scenario belongs to the first type of power supply unqualified scenario, the target startup protection mechanism includes: correcting the power factor or compensating the power factor.
[0125] Among them, the embodiments of the present application do not limit the specific power factor correction or compensation strategy too much and can be set according to actual needs.
[0126] 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 the power factor or compensating the power factor, the delay startup time can also be calculated according to the power data and the power supply fluctuation range.

[0132] 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 delay startup time can also be calculated according to the power data and the power supply fluctuation range.
[0133] Among them, for the calculation of the delay startup time in each of the above steps, specific reference can be made to Figure 6 the relevant descriptions in the embodiments shown.
[0134] S104, control the startup of the adapter and the electrical equipment based on the target startup protection mechanism.
[0135] After determining the target startup protection mechanism corresponding to the current startup scenario, the embodiments 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 the power overload scenario, the adapter and the electrical device can be started on the basis of overloading protection for the adapter. For another example, for the first type of power supply unqualified scenario, the adapter and the electrical device can be started on the basis of correcting or compensating the power factor. For yet another example, for the second type of power supply unqualified scenario, the adapter and the electrical device can be started on the basis of stabilizing the startup current for the startup current control. And for example, for the third type of power supply unqualified scenario, the adapter and the electrical device can be started on the basis of improving the power quality. In addition, if the calculation of the delayed startup time is involved, when controlling the startup of the adapter and the electrical device, the adapter is first controlled to start, and the electrical device is then controlled to start after the delayed startup time.
[0136] In the embodiments of the present application, before startup, the most suitable 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. Thus, each time the electrical device can reduce the power fluctuation during startup by starting based on the appropriate startup protection mechanism, has a strong scenario compatibility ability, can cope with various possible startup scenarios, and thus improves the smoothness during the startup process of the electrical device.
[0137] Specifically, by real-time monitoring the active power, power factor, and current fluctuation amplitude, and combining with the power quality index, it can be timely detected whether the adapter exceeds the maximum tolerated power or the power quality range, so as to adopt corresponding startup protection mechanisms, such as protection or compensation measures for startup, to ensure the safe and stable operation of the device.
[0138] As an optional embodiment of the present application, when multiple scenario requirements are satisfied simultaneously, the current startup scenario can belong to multiple scenarios at the same time, and at this time, the startup protection mechanisms can be executed synchronously. For example, when both the active power in S10311 exceeds the preset maximum tolerated power and the power factor in S10312 is lower than the preset minimum factor threshold are satisfied simultaneously, it can be determined that the current startup scenario belongs to both the power overload scenario and the first type of power supply unqualified scenario. At this time, the startup protection mechanisms respectively associated with both are the target startup protection mechanisms for the current startup scenario, that is, the protection mechanisms of both will run simultaneously. On the one hand, the adapter is subjected to overload protection based on S10321, and on the other hand, the power factor is corrected or compensated based on S10322. On the basis of both, the adapter and the electrical device are then started.
[0139] As an alternative embodiment of the present application, for the scenario of unqualified power quality, to avoid excessive backpressure on the adapter caused by the current impact during startup, the adapter and the electrical device can be started at different times to stagger the startup peaks of the adapter and the electrical device, thereby avoiding excessive instantaneous backpressure on the power supply, reducing the system load, and improving startup stability. Refer to Figure 6 , the embodiments of the present application include:
[0140] S1033, when the current startup scenario belongs to the scenario of unqualified power quality, the target startup protection mechanism includes: calculating the delay startup time according to the power data and the power fluctuation amplitude.
[0141] It can be understood that any scenario of unqualified power supply (including but not limited to the first type, the second type, and the third type of scenarios of unqualified power supply in the above embodiments) belongs to the scenario of unqualified power quality. In the embodiments of the present application, for the scenario of unqualified power quality, the adapter and the electrical device will be started at different times, that is, the electrical device will be started with a delay.
[0142] To avoid excessive backpressure on the adapter caused by the current impact during startup, the embodiments of the present application adopt an adjusted delay startup time ( Δt ) to stagger the startup peak of the electrical device and the fluctuation of the power supply system. In the embodiments of the present application, the power fluctuation amplitude includes the current fluctuation amplitude, and the calculation formula for the delay startup time is as follows:
[0143] Δt = α×(1 - ) + β×CFA (6)
[0144] Where: Δt is the adjusted delay startup time; is the power factor, which reflects the phase difference between the current and the voltage. 1− reflects the degree of power loss when the power factor is low, and also represents the risk caused by power fluctuations. The smaller, the longer the startup delay is required to give the electrical device 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 supply fluctuation. A larger CFA indicates a larger power supply fluctuation, and a longer startup delay is also required to smooth the fluctuation and reduce the impact during startup. α and β are adjustment parameters that respectively control the influence of the power factor and the power supply fluctuation amplitude on the startup delay.
[0145] The above parameters can be adjusted according to actual needs to optimize the startup stability of the device. (1 - ): Power factor affects the degree of current fluctuation, 1− The larger it is, the more serious the power supply fluctuation is, and the greater the impact that may occur during startup. By multiplying by the adjustment coefficient α, the startup delay can be appropriately extended to avoid the impact caused by the fluctuation. When the power supply fluctuation degree is large (i.e., CFA is large), a longer startup delay is also required so that the device can start stably step by step and avoid the problem of reverse voltage caused by excessive instantaneous current fluctuation. By adjusting the startup delay time, it is ensured that the startup spikes of the adapter and the electrical device are staggered, thereby avoiding excessive instantaneous reverse voltage of the power supply, reducing the system load, and improving the 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 the power supply. For example: if the power supply quality is relatively poor (i.e., low power factor and large power supply fluctuation range), then α and β need to be appropriately increased, 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., high power factor and small power supply fluctuation range), then α and β can be appropriately reduced to shorten the startup delay to improve the startup speed of the device. By adjusting the startup delay time Δt, the impact of unqualified power supply quality on the startup process of the adapter can be effectively reduced. Specifically, the influence of the power factor and the power supply fluctuation range on the delay is controlled by adjusting the parameters α and β respectively to ensure that the device can avoid the spikes of the power supply fluctuation during startup, thereby improving the stability of the startup process and avoiding excessive reverse voltage of the adapter.
[0146] During the startup process of the adapter and the electrical device, unqualified power supply quality (such as voltage fluctuation, poor power factor, etc.) may cause current impact (i.e., excessive instantaneous startup current) at the moment of startup of the electrical device. This current impact will cause excessive reverse voltage of the adapter, which may lead to device damage or instability. Therefore, it is crucial to avoid these problems by reasonably adjusting the startup delay time (Δt).
[0147] S1041, control the adapter to start, and then control the electrical device to start after the startup delay time.
[0148] On the basis of determining the startup delay time, when controlling the adapter and the electrical device to start, start the adapter first, and then start the electrical device after the startup delay time after the adapter starts. For example, assuming the startup delay time is 1s, then control the adapter to start first, and then control the electrical device to start 1s after the adapter starts.
[0149] By calculating the startup delay time Δt, there are at least the following benefits:
[0150] 1. Stagger the startup spikes. The startup spikes (i.e., instantaneous current impact) of the adapter and the electrical device can be staggered, avoiding the power supply system from bearing the startup impacts of two devices simultaneously, reducing the fluctuations of instantaneous voltage and current, reducing the pressure on the power supply system, and reducing the reverse voltage problem.
[0151] 2. By delaying the startup, the startup process of the device can be carried out during a period with less power fluctuation or more stable power supply, thereby reducing the problem of excessive backpressure of the adapter and improving the startup stability.
[0152] 3. By reasonably adjusting the delay startup time, it is ensured that the electrical equipment starts up smoothly and there will be no startup failure or instability of devices such as adapters due to excessive current fluctuations.
[0153] Therefore, the embodiments of the present application can excellently achieve the stable startup of the adapter and the electrical equipment, avoiding overvoltage of the power supply or damage to the equipment.
[0154] It should be specifically noted that the embodiments of the present application can be implemented independently or can be combined with Figure 5 the shown embodiments for combined implementation. That is, on the basis of time-sharing startup, for each refined scenario of unqualified power quality, at the same time, according to Figure 5 the content of the shown embodiments, operations such as power factor correction / compensation or current stability control are carried out.
