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

[0004] Existing power adapters typically use fixed conversion ratios or perform simple power adjustments based on load changes, failing to fine-tune adjustments based on real-time environmental changes. Many power adapter temperature control systems rely solely on simple temperature thresholds to determine whether to reduce output power, failing to consider the complex relationship between temperature and load. These simple control-rule-based temperature control strategies often lag behind and fail to respond promptly to rising temperatures, leading to device overheating or reduced energy efficiency. Therefore, the present invention provides a high-efficiency power conversion control method and power adapter to address these shortcomings in the existing technology. Summary of the Invention

[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the present specification. 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 making creative efforts are within the scope of protection of the present invention.

[0051] Please see the attached Figure 1 An embodiment of the present invention provides a high-efficiency power conversion control method. By collecting the input voltage, current, load, and temperature data of a power adapter in real time, and combining optimal control theory and the Pontryagin maximum principle to calculate the optimal conversion ratio, the method includes a signal detection module, a calculation and processing module, a feedback adjustment module, a temperature control module, and an output module. This method dynamically optimizes the working state of the power adapter under different load and ambient temperature conditions, thereby maximizing conversion efficiency and ensuring safe and stable operation of the device, reducing energy loss, and extending the service life of the device. The method includes the following steps:

[0052] S1. Real-time collection of power adapter input voltage, input current, load, and temperature data;

[0053] S2. Calculate the optimal conversion ratio of the power adapter based on the collected data;

[0054] S3. adjusting the output of the power adapter based on the calculated optimal conversion ratio;

[0055] S4. Monitor the operating temperature of the power adapter and automatically adjust the output power and conversion ratio;

[0056] S5. Continuously adjust the working state of the power adapter based on real-time changes in load and ambient temperature data;

[0057] S6. Dynamically adjust the temperature management strategy using a temperature penalty factor based on the operating temperature feedback of the power adapter;

[0058] S7. The conversion efficiency, temperature status, load adaptability, stability, reliability and safety status of the output power adapter.

[0059] For step S1, in this embodiment, the signal detection module is the core component of data acquisition, responsible for obtaining the key operating 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 output.

[0060] 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 the 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. Calculate the input power of the power adapter together with the voltage data , the calculation formula is:

[0061] ;

[0062] 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:

[0063] ;

[0064] 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.

[0065] Alternatively, the signal detection module's sensors can exchange data with the computing and processing module via wireless transmission technologies. For example, wireless technologies such as Bluetooth, Wi-Fi, or Zigbee can be used to transmit data to the central processing unit in real time. This approach facilitates data sharing between different power adapters, reduces wiring complexity, and improves system flexibility and scalability.

[0066] Specifically, in terms of temperature monitoring, the operating temperature of the power adapter Protecting the power adapter is crucial. When the operating temperature of the power adapter exceeds a certain threshold, the system needs to respond based on real-time temperature data and take appropriate temperature control measures. The temperature sensor's acquisition cycle is generally a few milliseconds to tens of milliseconds to ensure real-time data and timely reflection of the power adapter's operating status.

[0067] In some embodiments, the signal detection module can also combine filtering algorithms 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 load fluctuations or large temperature changes. Accurate data collection provides a key basis for subsequent control strategies.

[0068] In another possible implementation, the various sensors in the data acquisition module can use different sampling frequencies. Specifically, the voltage and current sampling frequencies are higher, typically hundreds of hertz, to ensure accurate tracking of the power adapter's input power. Temperature and load sampling frequencies, on the other hand, can be relatively low, typically tens of hertz, to avoid excessive computational overhead while still meeting temperature control and load regulation requirements.

[0069] 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 operating parameters of the power adapter according to the input data to ensure the conversion efficiency while avoiding overheating and loss. The optimal conversion ratio of the power adapter The calculation formula is as follows:

[0070] ;

[0071] 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.

[0072] 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.

[0073] Alternatively, the calculation of the optimal conversion ratio can also be combined with other optimization algorithms, such as genetic algorithms or particle swarm optimization, to more accurately solve the problem of maximizing conversion efficiency. These algorithms can quickly find the optimal solution under given constraints through an iterative optimization process, and can provide high calculation accuracy, especially when dealing with complex load and temperature variation patterns.

[0074] 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 status 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.

[0075] In one possible implementation, the computing and processing module can also use a model to predict load fluctuations and temperature trends based on historical data about the power adapter's load and temperature. This allows the module to proactively adjust the conversion ratio to avoid efficiency loss or overheating caused by sudden load or temperature fluctuations. For example, a machine learning model based on time series data (such as an LSTM network) can be used to predict future load and temperature changes and adjust the conversion ratio accordingly.

[0076] 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:

[0077] ;

[0078] 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 a co-state variable of temperature control, which is used to adjust the balance between temperature and energy efficiency.

[0079] 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 conditions are:

[0080] ;

[0081] 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 this equation. , thereby improving the energy efficiency of the power adapter.

[0082] This condition is solved at each point in time during the system processing 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.

[0083] In some embodiments, the optimal conversion ratio may be calculated using numerical methods. For example, gradient descent or dynamic programming can accelerate the calculation process and improve the system's real-time responsiveness. Numerical methods can effectively address the complexity of finding the optimal conversion ratio under load fluctuations or large temperature variations.

[0084] In another implementation, the calculation processing module may predict the optimal conversion ratio in the future based on historical load data and temperature trends, further improving the system's adaptability and responsiveness. This prediction method allows the power adapter to make adjustments in advance when the load fluctuates significantly, avoiding inefficiency or overheating during actual operation.

[0085] 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.

[0086] 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 Dynamic adjustment, 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.

[0087] For step S3, in this embodiment, the output regulation is achieved through a feedback control mechanism, which combines 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:

[0088] ;

[0089] 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.

[0090] Generally speaking, when the load on 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; when the temperature rises, the system will limit the output power by adjusting the optimal conversion ratio to prevent the system from overheating.

[0091] As an option, the process of regulating the output power is usually achieved by adjusting the switching element (such as MOSFET, IGBT), the working state of the switching element is driven by the control signal, which adjusts the duty cycle of the power adapter according to the calculated optimal conversion ratio and output power demand. :

[0092] ;

[0093] in, Indicates the output power of the power adapter. is the switching period, Is the duty cycle of the power adapter, which represents 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.

[0094] Specifically, when the power adapter has the optimal conversion ratio When the temperature 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.

[0095] 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 its output power, thereby lowering the temperature and protecting the device from overheating. This strategy can be achieved through the following formula:

[0096] ;

[0097] in, It is the output power of the power adapter after temperature control adjustment. Indicates the output power of the power adapter. is the set 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, thereby controlling the temperature of the power adapter.

[0098] In another possible implementation, the feedback regulation module can optimize the regulation of output power by coordinating 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.

[0099] In step S4, the safety and stability of the power adapter are improved, especially in high-load or high-temperature environments. By monitoring the operating temperature of the power adapter and automatically adjusting the output power and conversion ratio according to temperature changes, the system can ensure smooth operation under various operating conditions and prevent damage or efficiency loss caused by overheating.

[0100] 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 upper 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.

[0101] Generally, a power adapter maintains a certain temperature range under normal operating conditions. This range is usually determined by the device's design parameters. However, when the load increases or the ambient temperature rises, the power adapter's temperature will rise accordingly. In this case, 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 using the following formula:

[0102] ;

[0103] 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.

[0104] As an option, the temperature penalty factor It can be a dynamically changing value, which is 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.

[0105] Specifically, the temperature monitoring module regularly measures the power adapter's operating temperature and dynamically adjusts the output power and conversion ratio through the control system. For example, when the power adapter's temperature approaches a critical value, the system activates a preset cooling strategy, gradually reducing the output power to prevent the temperature from rising further. If the temperature continues to rise and exceeds the set maximum temperature, the system triggers a protection mechanism, cutting off unnecessary power output or limiting the power ceiling to minimize damage caused by overheating.

[0106] In another possible implementation, the temperature control module not only manages temperature by adjusting output power, but can also combine the system's workload information to intelligently predict temperature change trends and respond in advance. For example, through machine learning models or empirical prediction algorithms, 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.

[0107] 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.

[0108] In 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.

[0109] 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 The data is then 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 operation.

[0110] Specifically, when the load or ambient temperature changes, the system will adjust the power adapter's load according to the real-time 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:

[0111] ;

[0112] in, is the power adapter output power, For the conversion efficiency of dynamic calculation, The system can flexibly adjust the optimal conversion ratio of the power adapter according to the real-time load and temperature changes. and output power to keep the power adapter in optimal operating condition.

[0113] Generally, when the load increases, the power adapter output power 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.

[0114] Alternatively, when load and temperature fluctuate, the system can employ predictive modeling to anticipate future load fluctuations and temperature changes. By predicting future load changes, the system can make appropriate adjustments in advance to avoid instability caused by sudden load or temperature fluctuations. For example, machine learning algorithms can predict future load patterns and adjust the power adapter's operating state based on these predictions, improving adaptability and responsiveness.

[0115] 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 demand; and when the temperature changes, the system will adjust the output power according to the preset temperature control strategy to avoid overheating and equipment damage.

[0116] In some embodiments, the system may utilize feedback control algorithms, such as PID control algorithms, to precisely regulate the output power. By setting the desired load and temperature range, the system adjusts the conversion ratio and output power based on real-time data to ensure that the power adapter always remains in optimal condition during load changes and temperature fluctuations.

[0117] As a further improvement, the system can also incorporate historical data for optimization. When the power adapter operates continuously over a period of time, the system can learn from historical load and temperature changes to predict future trends and adjust operating conditions in advance. For example, the system can build a predictive model based on past temperature and load data to optimize output power and conversion ratio in advance.

[0118] For step S6, by further optimizing the temperature management strategy, based on the real-time operating temperature feedback of the power adapter, the temperature control mechanism is dynamically adjusted using the temperature penalty factor to protect the device from overheating or damage and ensure the safety and long-term reliability of the system.

[0119] In this embodiment, the temperature penalty factor Use the following calculation formula for dynamic adjustment:

[0120] ;

[0121] in, is the temperature penalty factor, is the proportional coefficient of the penalty factor, is the operating temperature of the power adapter, The upper temperature limit is set.

[0122] Specifically, the temperature penalty factor When the system detects that the temperature exceeds the preset range, it will automatically increase. At this time, the output power of the power adapter will be adjusted according to the output power of the power adapter after temperature control. 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.

[0123] In some embodiments, the temperature penalty factor The size of the temperature penalty factor can change dynamically rather than being a constant. In different working environments, the system can adjust the increase in the temperature penalty factor according to the speed and magnitude of temperature changes. For example, when the power adapter is in a state of rapid temperature rise, the temperature penalty factor can be increased rapidly to reduce power output as quickly as possible and prevent the temperature from rising sharply. When the temperature changes relatively slowly, the temperature penalty factor will increase relatively slowly to avoid over-adjustment that has a negative impact on system performance.

[0124] Specifically, the temperature penalty factor Dynamic adjustment can also be optimized in combination with load data. Generally speaking, 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. To achieve the best temperature control effect, for example, if the system is under a high load, the temperature will rise more rapidly, and the temperature penalty factor It may have a stronger impact on the output power; 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.

[0125] 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:

[0126] ;

[0127] in, Reflects the load of the power adapter and the operating temperature of the power adapter Optimal conversion ratio for power adapter impact.

[0128] In order to further improve conversion efficiency and manage 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:

[0129] ;

[0130] 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.

[0131] 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.

[0132] In some embodiments, the temperature penalty factor According to the working temperature of the power adapter Dynamic adjustment, when the operating temperature of the power adapter When approaching the preset safety limit, Will increase, thereby prompting the system to reduce power output to achieve the effect of temperature control. 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.

[0133] As a further improvement, temperature management strategies can be optimized not only by relying on current temperature data but also by incorporating historical data. By analyzing past temperature trends, the system can predict future temperature fluctuations and adjust the temperature penalty factor in advance to avoid sudden overheating. For example, by performing regression analysis on historical load and temperature data, the system can predict possible future temperature peaks based on load and temperature variation patterns and reduce output power in advance.

These performance indicators not only provide a basis for long-term monitoring and maintenance of the device, but also help users and technicians understand the power adapter's operating status in real time and make further adjustments as needed.

[0135] 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:

[0137] 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.

[0138] In general, the conversion efficiency of the power adapter It is affected by input voltage, current, load, and temperature. Conversion efficiency typically decreases under heavy loads or high temperatures. By calculating real-time conversion efficiency, the system provides timely feedback on whether the power adapter is operating optimally. If conversion efficiency drops significantly, the system can restore optimal efficiency by adjusting output power and conversion ratio.

[0139] Power adapter operating temperature It also becomes a key parameter for evaluating the operating status of the power adapter. Real-time monitoring of the power adapter's operating temperature can effectively prevent device overheating or damage. Temperature data is used to calculate a temperature penalty factor and trigger temperature control strategies when safety thresholds are exceeded, thereby ensuring system safety.

[0140] As an option, a power adapter load This can be assessed by the power adapter's responsiveness. Specifically, load adaptability reflects the adapter's stability and flexibility in response to load changes. For example, in the presence of large load fluctuations, the power adapter should be able to quickly adjust its output power to avoid system instability or inefficiency caused by rapid load changes.

[0141] 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 adjust strategies as needed. In addition, monitoring 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.

[0142] 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.

[0143] 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 always remains in the best working condition.

[0144] As an improved solution, the system can also synchronize the output key performance indicators to the cloud monitoring platform. Users can obtain real-time operating data of the power adapter through remote access, further improving the management efficiency and response speed of the power adapter.

[0147] 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.

Through precise data collection, the system can timely identify the working status of the power adapter and make adjustments when necessary.

[0149] The calculation and processing module is used to calculate the optimal conversion ratio of the power adapter based on 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 its working state under different load and temperature conditions.

[0150] 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 system's conversion efficiency, 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.

By continuously adjusting the output, the feedback regulation module ensures that the power adapter can adapt to changes in different load and ambient temperature conditions and always achieve the optimal conversion efficiency.

[0152] 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.

[0153] The temperature control module monitors the power adapter's operating temperature in real time and takes regulatory action when the temperature reaches a preset threshold to prevent overheating. Using a temperature sensor, the system can detect temperature changes in the power adapter and adjust the output power or conversion ratio based on the real-time temperature.

[0154] When the temperature approaches the set upper 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.

[0155] The output module provides users with the power adapter's final operating status, including key information such as conversion efficiency, output power, load adaptability, and temperature. Through the display or other data output interfaces, users can view the power adapter's operating status in real time, ensuring the device is always operating safely and efficiently.

[0156] In addition, the output module can also synchronize the working status data of the power adapter to the remote monitoring system or cloud platform, allowing operation and maintenance personnel to 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.
