Technical Field

[0001] The present invention relates to the technical field of electronic equipment, and in particular to a high-efficiency power conversion control method and a power adapter. Background Art

[0002] With the rapid development of information technology and consumer electronics, power adapters, as an important component of various electrical devices, are widely used in mobile phones, laptops, televisions, home appliances and industrial equipment. The main function of the power adapter is to convert the input voltage into a stable output voltage suitable for the operation of the equipment while maintaining efficient energy conversion.

[0003] Existing high-efficiency power conversion control methods mostly optimize energy efficiency through fixed conversion ratios or control strategies based on preset load and temperature conditions. For example, some control methods adjust the output of the power adapter by using linear regulation or optimization algorithms based on load prediction in order to achieve higher conversion efficiency. In addition, many power adapters also use temperature control mechanisms. When the temperature reaches the set threshold, the system will automatically reduce power output or adjust the working state to avoid damage caused by overheating.

[0004] Existing power adapters usually use a fixed conversion ratio or only perform simple power adjustments according to load changes, and cannot perform fine adjustments according to real-time environmental changes. The temperature control systems of many power adapters only rely on simple temperature thresholds to decide whether to reduce the output power, and fail to consider the complex relationship between temperature and load. This temperature control strategy based on simple control rules is often too lagging and cannot respond in time when the temperature rises, resulting in overheating of the device or reduced energy efficiency. Therefore, the present invention provides a high-efficiency power conversion control method and a power adapter to solve the deficiencies in the prior art. Summary of the invention

[0013] Preferably, the operating temperature feedback is provided by real-time monitoring of the operating temperature of the power adapter. When the temperature approaches the set upper temperature limit When the temperature exceeds the safe temperature, the temperature feedback mechanism is triggered to adjust the working state of the power adapter according to the monitored temperature data. The temperature feedback mechanism includes the introduction of a temperature penalty factor. The temperature penalty factor is dynamically adjusted according to the deviation between the temperature and the safe temperature to limit the conversion ratio when the temperature rises.

[0021] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Please refer to the attached Figure 1 The embodiment of the present invention provides a high-efficiency power conversion control method, which collects the input voltage, current, load and temperature data of the power adapter in real time, combines the optimal control theory and the Pontryagin maximum principle to calculate the optimal conversion ratio, includes a signal detection module, a calculation processing module, a feedback adjustment module, a temperature control module and an output module, realizes dynamic optimization of the working state of the power adapter under different load and ambient temperature conditions, thereby maximizing the conversion efficiency and ensuring the safe and stable operation of the equipment, reducing energy loss and extending the service life of the equipment, including the following steps: S1.

Conversion efficiency, temperature status, load adaptability, stability, reliability and safety status of the output power adapter.

[0023] For step S1, in this embodiment, the signal detection module is the core component of data acquisition, responsible for obtaining the key working parameters of the power adapter through various sensors, and can monitor various operating indicators of the power adapter in real time, providing necessary data support for the subsequent calculation of the optimal conversion ratio and dynamic adjustment of the output.

[0024] Generally, the signal detection module includes a voltage sensor, a current sensor, a load monitoring sensor, and a temperature sensor. The voltage sensor is used to monitor the input voltage of the power adapter in real time. The output data will provide a basis for calculating the input power and controlling the conversion efficiency of the power adapter. The current sensor measures the input current of the power adapter. , and together with the voltage data, calculate the input power of the power adapter , the calculation formula is: ; in, Indicates the input power of the power adapter. Indicates the input voltage of the power adapter. Indicates the input current of the power adapter. The load of the power adapter can be obtained by the relationship between the output power and the load. Specifically, the load and the output power of the power adapter The relationship between them is usually: ; in, The output voltage of the power adapter, which indicates the voltage at the output end of the power adapter when it is working. Indicates the load of the power adapter. Indicates the output power of the power adapter. The temperature sensor is responsible for measuring the operating temperature of the power adapter. This is an important basis for temperature control and regulation to prevent the power adapter from being damaged in an overheated state. The temperature sensor is usually a thermistor (NTC or PTC), which can accurately obtain the temperature information inside or outside the power adapter.

[0025] As an option, the sensor of the signal detection module can exchange data with the computing processing module through wireless transmission technology. For example, data can be transmitted to the central processing unit in real time through wireless technologies such as Bluetooth, Wi-Fi or Zigbee. This method facilitates data sharing between different power adapters, while reducing the complexity of wiring and improving the flexibility and scalability of the system.

[0026] Specifically, in terms of temperature monitoring, the operating temperature of the power adapter The protection of the power adapter is crucial. When the operating temperature of the power adapter exceeds a certain threshold, the system needs to respond based on the real-time temperature data and take corresponding temperature control measures. The acquisition cycle of the temperature sensor is generally a few milliseconds to tens of milliseconds to ensure the real-time data and to be able to reflect the working status of the power adapter in a timely manner.

[0027] In some embodiments, the signal detection module can also combine the filtering algorithm to remove noise from the collected voltage, current, load and temperature data. For example, using a Kalman filter or a low-pass filter can effectively filter out high-frequency noise in the signal, thereby improving the accuracy and stability of the data. This is particularly important for ensuring the efficient operation of the power adapter, especially in the case of large load fluctuations or temperature changes. The accurate collection of data provides a key basis for subsequent control strategies.

[0028] In another possible implementation, each sensor in the data acquisition module can use different sampling frequencies. Specifically, the sampling frequency of voltage and current is relatively high, usually hundreds of hertz, to ensure that the input power of the power adapter can be accurately tracked. The sampling frequency of temperature and load can be relatively low, usually tens of hertz, to avoid excessive calculation burden while meeting the requirements of temperature control and load regulation.

[0029] For step S2, in this embodiment, the calculation of the optimal conversion ratio of the power adapter adopts the optimal control theory, especially the Pontryagin maximum principle. Through this theory, the system can dynamically adjust the working parameters of the power adapter according to the input data, so that it can avoid overheating and loss while ensuring the conversion efficiency. The optimal conversion ratio of the power adapter The calculation formula is as follows: ; in, Indicates the conversion efficiency of the power adapter, which depends on the optimal conversion ratio of the power adapter , power adapter load and the operating temperature of the power adapter relationship, is the input power of the power adapter, which is calculated from the input voltage and current. is the optimal conversion ratio of the power adapter. The goal of calculating the optimal conversion ratio is to maximize the conversion efficiency of the power adapter.

[0030] In general, the conversion efficiency It will change with the load and temperature of the power adapter. Specifically, when the load increases, the power adapter may need to increase the output power to maintain load stability. When the temperature rises, the system will adjust the conversion ratio to prevent overheating. By calculating the optimal conversion ratio, the power adapter can dynamically adjust under these conditions to maintain optimal efficiency.

[0031] As an option, the calculation of the optimal conversion ratio can also be combined with other optimization algorithms, such as genetic algorithms or particle swarm algorithms, to more accurately solve the problem of maximizing the conversion efficiency. These algorithms can quickly find the optimal solution under given constraints through an iterative optimization process, especially when dealing with complex load and temperature variation patterns, and can provide higher calculation accuracy.

[0032] Specifically, the calculation processing module calculates the load of the power adapter according to the and the operating temperature of the power adapter The real-time changes of the power adapter are combined with historical data and forecast information to calculate the optimal conversion ratio of the dynamic power adapter. This process is generally achieved through iterative solution, that is, after each calculation, the optimal conversion ratio will be applied to the adjustment of the power adapter, and as the system state changes, the calculation results will be continuously updated. This dynamic adjustment can ensure that the power adapter can maintain efficient and stable operation under any environmental conditions.

[0033] In one possible implementation, the computing and processing module can also predict the trend of load fluctuation and temperature change through a model based on the historical data of the load and temperature of the power adapter, so as to adjust the conversion ratio in advance to avoid efficiency loss or overheating due to sudden load changes or temperature fluctuations. For example, a machine learning model based on time series data (such as an LSTM network) is used to predict future load and temperature changes, and adjust the conversion ratio accordingly.

[0034] In this embodiment, the calculation of the optimal conversion ratio adopts the Pontryagin maximum principle. This theoretical method can be constructed by constructing the Hamiltonian To perform optimal control, where: ; in, Indicates the conversion efficiency of the power adapter. is the state equation of the power adapter, reflecting the load of the power adapter and the operating temperature of the power adapter Optimal conversion ratio for power adapter The impact of The optimal conversion ratio for the power adapter The rate of change over time, It is the co-variable of temperature control and is used to adjust the balance between temperature and energy efficiency.

[0035] In general, the system calculates the derivative of the Hamiltonian and solves its optimization to obtain the optimal conversion ratio of the power adapter. , the optimization condition is: ; Among them, the Hamiltonian Combining the conversion efficiency and temperature control of the power adapter, the optimal conversion ratio of the power adapter can be obtained by solving the equation , thereby improving the energy efficiency of the power adapter.

[0036] This condition will be solved at each time point in the system processing process to obtain the conversion ratio that best suits the current working conditions. By solving this optimization problem, the power adapter can effectively control the temperature while ensuring conversion efficiency to avoid overheating or energy waste.

[0037] In some embodiments, the calculation of the optimal conversion ratio may also be solved in combination with numerical methods. For example, using a gradient descent method or a dynamic programming method can speed up the calculation process and improve the real-time response capability of the system. Numerical methods can effectively solve the complexity of solving the optimal conversion ratio in the case of load fluctuations or large temperature changes.

[0038] In another implementation, the calculation processing module may make predictions based on historical load data and temperature trends, and calculate the optimal conversion ratio in the future in advance, further improving the adaptability and responsiveness of the system. This prediction method allows the power adapter to make adjustments in advance when the load changes greatly, avoiding inefficiency or overheating of the system during actual operation.

[0039] Specifically, the optimal conversion ratio of the power adapter is calculated It will be used in the feedback regulation module to adjust the output power and working mode of the power adapter in real time. Through this process, the system can achieve fine control of the power adapter, thereby improving energy utilization and reducing energy waste.

[0040] In some embodiments, the calculation processing module may combine a temperature penalty factor to further optimize the calculation of the conversion ratio. is based on the current operating temperature of the power adapter Dynamically adjusted, if the temperature is too high, the system will reduce the power output by reducing the conversion ratio, thereby reducing the temperature. For example, when the temperature exceeds a certain preset threshold, the temperature penalty factor Increases, forcing the system to reduce output power to avoid the risk of overheating.

[0041] For step S3, in this embodiment, the output regulation is achieved through a feedback control mechanism, combining the input power and real-time monitoring data to adjust the output power of the power adapter. The relationship between output power and input power can be expressed by the following formula: ; in, It is based on the optimal conversion ratio of the power adapter , power adapter load and the operating temperature of the power adapter Adjusted conversion efficiency, is the power adapter input power, To output power to the power adapter, in order to ensure that the power adapter works at optimal efficiency, the feedback regulation module dynamically adjusts the output power according to the optimal conversion ratio.

[0042] Generally, when the load of the power adapter increases or the temperature rises, the system will adjust the output power appropriately to adapt to the changes. For example, when the load increases, in order to maintain a stable output voltage, the power adapter needs to increase the output power; and when the temperature rises, the system will limit the output power by adjusting the optimal conversion ratio to prevent the system from overheating.

[0043] Alternatively, the process of regulating the output power is usually achieved by adjusting the switching element (e.g., MOSFET, IGBT), the operating state of the switching element is driven by a control signal, which adjusts the duty cycle of the power adapter according to the calculated optimal conversion ratio and output power demand. : ; in, Indicates the output power of the power adapter. is the switching cycle, is the duty cycle of the power adapter, which indicates the ratio of the on-time of the switching element to the total cycle. Indicates the input power of the power adapter. Adjusting the duty cycle can effectively control the output power and ensure that the output of the power adapter is consistent with the calculated optimal power.

[0044] Specifically, when the power adapter has the optimal conversion ratio When it increases, it means that the system needs to provide more output power to maintain high efficiency. At this time, the feedback control system will increase the duty cycle to allow more power output; when the temperature rises or the load decreases, the system controls the output power by reducing the duty cycle to prevent overheating and excessive power output. In this way, the power adapter can achieve precise power regulation, maximize efficiency and maintain system stability.

[0045] In some embodiments, the feedback regulation module may be combined with a temperature control strategy to further optimize the output power. When the preset safety threshold is exceeded, the temperature penalty factor will automatically increase. The power adapter reduces the output power, thereby reducing the temperature and protecting the device from overheating damage. This strategy can be achieved through the following formula: ; in, It is the output power of the power adapter after temperature control adjustment. Indicates the output power of the power adapter. is the upper temperature limit, Indicates the operating temperature of the power adapter. Represents the temperature penalty factor. As the temperature exceeds the safe range, the temperature penalty factor Increases, forcing the system to reduce output power and thus control the temperature of the power adapter.

[0046] In another possible implementation, the feedback regulation module can optimize the regulation of output power by working with an external temperature control system. For example, when the temperature control system detects that the device is overheating, the feedback regulation module will quickly lower the output power according to the temperature control requirements and gradually resume normal operation after the temperature returns to a safe range.

[0047] For step S4, the safety and stability of the power adapter are improved, especially under high load or high temperature environment. By monitoring the operating temperature of the power adapter and automatically adjusting the output power and conversion ratio according to the temperature change, the system can be ensured to operate smoothly under various working conditions and prevent damage or efficiency reduction caused by overheating.

[0048] In this embodiment, the operating temperature of the power adapter The temperature sensor is used for real-time monitoring and the temperature data is transmitted to the control system. When the operating temperature exceeds the set temperature limit, When the system automatically takes adjustment measures to reduce the output power of the power adapter Or adjust the optimal conversion ratio of the power adapter , to reduce the thermal load of the system and avoid equipment damage or efficiency loss due to overheating.

[0049] Generally, the power adapter will maintain a certain temperature range under normal working conditions. Usually, this range is determined by the design parameters of the device. However, when the load increases or the ambient temperature rises, the temperature of the power adapter will rise accordingly. In this case, in order to prevent overheating, the system will dynamically adjust the output power and conversion ratio to keep the temperature within a safe range. Specifically, the temperature control strategy can be implemented by the following formula: ; in, It is the output power of the power adapter after temperature control adjustment. is the power adapter output power, is the temperature penalty factor, which indicates the effect of temperature rise on output power. is the operating temperature of the power adapter, The upper temperature limit is set. When the operating temperature of the power adapter Exceeding the set temperature limit When the system increases the temperature penalty factor , reducing output power and thus alleviating the thermal burden on the equipment.

[0050] As an option, the temperature penalty factor It can be a dynamically changing value, adjusted according to the temperature changes monitored in real time. When the power adapter is working, It can be adjusted according to the temperature curve. For example, when the temperature rises rapidly, the temperature penalty factor can be increased rapidly, forcing the system to reduce output power; when the temperature drops, the temperature penalty factor can be reduced, thereby restoring normal output power.

[0051] Specifically, the temperature monitoring module will regularly measure the operating temperature of the power adapter and dynamically adjust the output power and conversion ratio through the control system. For example, when the temperature of the power adapter approaches the critical value, the system will start the preset cooling strategy and gradually reduce the output power to ensure that the temperature does not continue to rise. If the temperature continues to rise and exceeds the set maximum temperature value, the system will trigger the protection mechanism to cut off some unnecessary power output or limit the power upper limit, thereby minimizing damage caused by overheating.

[0052] In another possible implementation, the temperature control module not only manages the temperature by adjusting the output power, but also can combine the system's workload information to intelligently predict the temperature change trend and respond in advance. For example, through a machine learning model or an empirical prediction algorithm, the system can predict future temperature changes based on load history and temperature change patterns, and make adjustments before the temperature approaches the threshold to avoid the occurrence of a critical state.

[0053] In some embodiments, temperature regulation not only relies on the temperature penalty factor, but can also be comprehensively adjusted in combination with load change information. When the load increases, the system will appropriately increase the conversion ratio, but at the same time limit it according to the temperature conditions to avoid excessive output power causing a sharp increase in temperature. Specifically, the system will dynamically optimize the combination of output power and conversion ratio based on the relationship between load and temperature, so as to meet load requirements while maintaining a safe temperature.

[0054] For step S5, the working state of the power adapter is continuously adjusted according to the real-time changing load and ambient temperature data to cope with possible load fluctuations and changes in ambient temperature, thereby further improving the adaptability and operating efficiency of the power adapter.

[0055] In this embodiment, the working state of the power adapter is adjusted based on the load of the power adapter collected in real time. and the operating temperature of the power adapter Data will be passed to the control system as input. Based on this real-time data, the system will calculate whether the output power or conversion ratio needs to be adjusted to maintain efficient power conversion and stable working conditions.

[0056] Specifically, when the load or ambient temperature changes, the system will adjust the power adapter according to the load of the real-time power adapter. and the operating temperature of the power adapter Data dynamically calculates the required power adapter output power Optimal conversion ratio with power adapter . These data can be expressed by the following relationship: ; in, is the power adapter output power, For the dynamic calculation of conversion efficiency, The input power of the power adapter. According to the real-time load and temperature changes, the system can flexibly adjust the optimal conversion ratio of the power adapter. and output power to keep the power adapter in optimal operating condition.

[0057] Generally, when the load increases, the output power of the power adapter needs to increase to meet the load demand. At this time, the system will adjust the optimal conversion ratio of the power adapter. To ensure maximum energy efficiency. When the ambient temperature is high, the system will automatically reduce the output power and adjust the conversion ratio to avoid overheating and ensure that the device operates within a safe temperature range.

[0058] As an option, when the load and temperature change, the system can use a predictive model-based approach to estimate future load fluctuations and temperature changes. By predicting future load changes, the system can make corresponding adjustments in advance to avoid instability caused by sudden loads or temperature fluctuations. For example, by predicting future load patterns through machine learning algorithms, and adjusting the working state of the power adapter based on these predictions, it can improve adaptability and responsiveness.

[0059] Specifically, the system inputs the load of the power adapter that changes in real time and the operating temperature of the power adapter Data, combined with the optimal conversion ratio of the power adapter calculated previously , dynamically adjust the output power. When the load changes, the system will gradually increase the output power to meet the load requirements; when the temperature changes, the system will adjust the output power according to the preset temperature control strategy to avoid overheating and equipment damage.

[0060] In some embodiments, the system may utilize feedback control algorithms, such as a PID control algorithm, to precisely regulate the output power. By setting the desired load and temperature range, the system will adjust the conversion ratio and output power based on real-time data to ensure that the power adapter always remains in the best condition during load changes and temperature fluctuations.

[0061] As a further improvement, the system can also be optimized in combination with historical data. When the power adapter is running continuously for a period of time, the system can learn the changing patterns of historical load and temperature, predict future changing trends and adjust the working state in advance. For example, the system can establish a prediction model based on past temperature and load data to optimize the output power and conversion ratio in advance.

[0062] For step S6, by further optimizing the temperature management strategy, based on the real-time operating temperature feedback of the power adapter, the temperature penalty factor is used to dynamically adjust the temperature control mechanism to protect the device from overheating or damage and ensure the safety and long-term reliability of the system.

[0063] In this embodiment, the temperature penalty factor Use the following calculation formula for dynamic adjustment: ; in, is the temperature penalty factor, is the proportionality coefficient of the penalty factor, is the operating temperature of the power adapter, The upper temperature limit is set.

[0064] Specifically, the temperature penalty factor When the system detects that the temperature exceeds the preset range, the output power of the power adapter will automatically increase according to the output power of the power adapter after temperature control adjustment. As the temperature returns to a safe range, the temperature penalty factor It will gradually return to normal values, and the system will increase the output power again to ensure that the power adapter can operate smoothly under changes in load and temperature.

[0065] In some embodiments, the temperature penalty factor The size of can be dynamically changed instead of being a constant. In different working environments, the system can adjust the increase of the temperature penalty factor according to the speed and amplitude of temperature change. For example, when the power adapter is in a state of rapid heating, the temperature penalty factor can be increased rapidly to reduce the power output as quickly as possible and prevent the temperature from rising sharply. In the case of relatively gentle temperature changes, the temperature penalty factor will increase relatively slowly to avoid over-adjustment and negative impact on system performance.

[0066] Specifically, the temperature penalty factor The dynamic adjustment can also be optimized in combination with load data. Generally, an increase in load will lead to an increase in power demand, which will increase the temperature. In this case, the system will adjust according to the relationship between real-time load and temperature. , in order to achieve the best temperature control effect. For example, if the system is under a higher load, the temperature will rise more rapidly, and the temperature penalty factor It may affect the output power more strongly; while under lower load conditions, the temperature rises more slowly and the impact of the temperature penalty factor on the output power is relatively small.

[0067] In this embodiment, the operating temperature of the power adapter It is controlled by the temperature equation, and its change is expressed by the following formula: ; in, Reflects the load of the power adapter and the operating temperature of the power adapter Optimal conversion ratio for power adapter impact.

[0068] In order to further improve the conversion efficiency and manage the temperature, the system needs to consider the balance between temperature and conversion efficiency during the optimization process. Specifically, the objective function of the system can be defined as follows: ; in, Indicates the optimal conversion ratio by optimizing the power adapter , is the temperature penalty factor, is the first term in the objective function, The second target function.

[0069] Specifically, the optimization process solves the above objective function to obtain the optimal conversion ratio of the power adapter. , and adjust the working mode of the power adapter accordingly, by introducing a temperature penalty factor , the system can actively reduce the output power when the temperature is too high, thereby lowering the temperature and avoiding overheating problems.

[0070] In some embodiments, the temperature penalty factor Depending on the operating temperature of the power adapter Dynamically adjust when the power adapter's operating temperature When approaching the preset safety limit, Will increase, thereby prompting the system to reduce power output, achieving the effect of controlling temperature. The optimized temperature management is combined with the optimized conversion efficiency process to ensure that the power adapter always operates in an efficient and safe state.

[0071] As a further improvement, the temperature management strategy not only relies on current temperature data, but can also be optimized in combination with historical data. By analyzing past temperature change trends, the system can predict future temperature changes and adjust the size of the temperature penalty factor in advance to avoid sudden overheating problems. For example, by performing regression analysis on historical load and temperature data, the system can predict possible temperature peaks in the future based on the load and temperature change patterns, and reduce output power in advance.

[0072] For step S7, the various working states of the power adapter are comprehensively evaluated, and key performance indicators such as conversion efficiency, temperature state, load adaptability, stability and reliability, and safety state are output. These performance indicators not only provide a basis for long-term monitoring and maintenance of the equipment, but also help users and technicians understand the working status of the power adapter in real time and make further adjustments as needed.

[0073] In this embodiment, the system continuously monitors the working status of the power adapter through the control module and outputs the following key indicators to the user interface or cloud monitoring platform: conversion efficiency , Working temperature of power adapter , power adapter load , system stability and reliability, and security status. These indicators are calculated and fed back using the following formula: ; in, Output power for the power adapter, is the input power of the power adapter, It reflects the energy conversion efficiency of the power adapter under different working conditions and can directly measure the energy efficiency of the power adapter.

[0074] Generally speaking, the conversion efficiency of the power adapter It is affected by input voltage, current, load and temperature. When the load is large or the temperature is high, the conversion efficiency usually decreases. By calculating the real-time conversion efficiency, the system can promptly feedback whether the power adapter is in the best working state. If the conversion efficiency drops significantly, the system can restore the best efficiency by adjusting the output power and conversion ratio.

[0075] Power adapter operating temperature It will also become one of the key parameters for evaluating the operating status of the power adapter. Real-time monitoring of the operating temperature of the power adapter can effectively prevent the device from overheating or damage. The temperature data is used to calculate the temperature penalty factor and trigger the temperature control strategy when it exceeds the safety threshold, thereby ensuring the safety of the system.

[0076] As an option, a power adapter load It can be evaluated by the responsiveness of the power adapter. Specifically, load adaptability reflects the stability and flexibility of the power adapter when the load changes. For example, when the load fluctuates greatly, the power adapter should be able to quickly adjust the output power to avoid system instability or inefficiency due to too fast load changes.

[0077] Specifically, the stability and reliability of the system usually depend on multiple factors, such as the comprehensive performance of conversion efficiency, temperature management and load response. By continuously monitoring these parameters, the system can evaluate the overall stability of the power adapter and provide feedback and adjustment strategies as needed. In addition, monitoring of the safety status is also one of the core parts of this step. The safety status usually includes whether the power adapter is in an abnormal state such as overload, overheating or short circuit. The system ensures that the power adapter can operate within a safe range under any circumstances through real-time monitoring.

[0078] In some embodiments, the system can also calculate a comprehensive health score of the power adapter based on multiple factors such as conversion efficiency, temperature status, load adaptability, etc. This score can help users or operation and maintenance personnel determine whether the power adapter requires further inspection or maintenance, and ensure the long-term reliability of the equipment through regular evaluation.

[0079] To further enhance the intelligence of the system, the output performance indicators can be optimized in combination with machine learning or artificial intelligence algorithms. For example, by learning from historical data, the system can predict the performance of the power adapter under different environmental conditions and adjust the operating strategy in advance based on the prediction results. This can prevent possible failures or performance degradation in advance and ensure that the power adapter is always in the best working condition.

[0080] As an improved solution, the system can also synchronize the output key performance indicators to the cloud monitoring platform. Users can obtain the real-time operation data of the power adapter through remote access, further improving the management efficiency and response speed of the power adapter.

[0081] The high-efficiency power adapter described below and the high-efficiency power conversion control method described above can be referred to each other.

[0082] Please refer to the attached Figure 2 The present invention also provides a high-efficiency power adapter, which can adjust its working state in real time under different load and ambient temperature conditions by combining a signal detection module, a calculation processing module, a feedback adjustment module, a temperature control module and an output module, thereby maximizing the conversion efficiency and ensuring the safe and stable operation of the equipment. By optimizing the conversion ratio and the intelligent temperature control strategy, the power adapter not only improves the energy utilization efficiency, but also effectively avoids the overheating problem, prolongs the service life of the equipment, and meets the requirements of efficient, safe and reliable operation.

[0083] The signal detection module is used to collect multiple working parameters of the power adapter in real time, including input voltage, input current, output voltage, output current, load and temperature. These data provide an important basis for subsequent control and optimization. Temperature and load changes have a direct impact on the efficiency and safety of the power adapter, and the input and output currents are closely related to the power conversion efficiency of the power adapter.

[0084] The signal detection module is usually composed of multiple high-precision sensors, which can stably and accurately collect data during the operation of the power adapter. Through precise data collection, the system can timely identify the working status of the power adapter and make adjustments when necessary.

[0085] The calculation and processing module is used to calculate the optimal conversion ratio of the power adapter according to the collected real-time data through optimal control theory and Pontryagin maximum principle. The calculation result will be input into the feedback adjustment module as feedback to guide the power adapter to adjust the working state under different load and temperature conditions.

[0086] This module uses advanced calculation algorithms to calculate the optimal conversion ratio in real time based on data such as input voltage, input current, load and temperature, and dynamically adjust the control strategy. In order to maximize the conversion efficiency of the system, the calculation processing module combines these calculation results with real-time data to ensure that the power adapter always works in the best operating state.

[0087] The feedback regulation module is used to adjust the output voltage and current of the power adapter according to the optimal conversion ratio provided by the calculation processing module. By continuously adjusting the output, the feedback regulation module ensures that the power adapter can adapt to changes under different load and ambient temperature conditions and always achieve the optimal conversion efficiency.

[0088] The feedback regulation module monitors the working status of the power adapter in real time through a closed-loop control mechanism to ensure that the voltage and current output are consistent with the optimal conversion ratio. When the load changes or the temperature fluctuates, the feedback regulation module can respond quickly and automatically adjust the output power and conversion ratio to cope with changes in external conditions.

[0089] The temperature control module is responsible for real-time monitoring of the operating temperature of the power adapter and taking regulatory measures when the temperature reaches the preset threshold to prevent the device from overheating. Through the temperature sensor, the system can detect the temperature change of the power adapter in time and adjust the output power or conversion ratio according to the real-time temperature.

[0090] When the temperature approaches the set upper temperature limit When the temperature control module automatically increases the temperature penalty factor , forcing the system to reduce output power to ensure that the device temperature does not continue to rise, thereby avoiding overheating problems. In addition, the temperature control module can also make predictions based on historical temperature data and load changes, and take measures in advance to prevent overheating.

[0091] The output module is used to provide users with the final working status of the power adapter, including key information such as conversion efficiency, output power, load adaptability, temperature status, etc. Through the display or other data output interface, users can view the operating status of the power adapter in real time to ensure that the device is always in a safe and efficient working state.

[0092] In addition, the output module can also synchronize the working status data of the power adapter to the remote monitoring system or cloud platform, so that operation and maintenance personnel can remotely monitor the operation of the equipment, perform diagnosis and maintenance in a timely manner, and further improve the reliability and service life of the power adapter.

[0093] The device of this embodiment can be used to execute the above method embodiment, and its principles and technical effects are similar, which will not be repeated here.
