[0041] The principles and spirit of the present invention will be described below with reference to several exemplary embodiments. It should be understood that these embodiments are provided only to enable those skilled in the art to better understand and implement the present invention, and are not intended to limit the scope of the present invention in any way. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.
[0042] Those skilled in the art know that the embodiments of the present invention can be implemented as a system, device, apparatus, method or computer program product. Therefore, the present invention can be specifically implemented in the following forms, namely: complete hardware, complete software (including firmware, resident software, microcode, etc.), or a combination of hardware and software.
[0043] It should be noted that any number of elements in the drawings is for illustration rather than limitation, and any naming is only for distinction and does not have any limiting meaning.
[0044] Reference below Figure 1 , Figure 1 FIG. 1 is a flow chart of an adaptive blanking timing circuit control method provided by an embodiment of the present invention. Figure 1 As shown, an adaptive blanking timing circuit control method 100 includes:
[0045] Step 101, determining a blanking time parameter according to an input voltage signal, and constructing an adaptive blanking timing circuit model to obtain a blanking time diagram;
[0046] Step 102, adjusting the blanking time parameter according to the load condition and the feedback signal to achieve dynamic control of the adaptive blanking timing circuit; and
[0047] Step 103, controlling the leading edge blanking time of the circuit according to the blanking time diagram and the adjusted blanking time parameters to optimize the load carrying capacity and standby power consumption of the circuit.
[0048] It should be noted that this embodiment relates to an adaptive blanking timing circuit control method, which dynamically adjusts the blanking time parameters by monitoring the input voltage signal and load conditions to achieve optimal control of the circuit. This method can automatically adjust the blanking time according to real-time voltage and load changes to adapt to different working conditions.
[0049] Specifically, the input voltage signal can be a DC voltage or an AC voltage, and the load condition can be a light load, a medium load, or a heavy load. The blanking time parameter is determined by a voltage signal detection module and a load condition detection module. These modules can be hardware circuits or software algorithms for real-time monitoring and analysis of input voltage and load conditions.
[0050] Preferably, the blanking time parameter adjustment can be achieved by an algorithm that calculates a new blanking time parameter based on the voltage value of the input voltage signal and the load condition. For example, a lookup table can be used to store the optimal blanking time parameters under different voltage and load conditions, or a mathematical model can be used to dynamically calculate the blanking time parameters. In addition, a feedback mechanism can be introduced to fine-tune the blanking time parameters according to the actual performance of the circuit to achieve more precise control.
[0051] In some embodiments, the adaptive blanking timing circuit control method according to claim 1 is characterized in that adjusting the blanking time parameter further includes determining the blanking time parameter according to the input voltage signal and the load condition.
[0052] It should be noted that this embodiment further refines how to adjust the blanking time parameters according to the input voltage signal and the load condition. Through this adjustment, the circuit can respond to different working conditions more accurately, thereby optimizing its performance.
[0053] Specifically, the process of adjusting the blanking time parameter can be implemented by the following steps: First, the first voltage value of the input voltage signal is determined by the voltage signal detection module, which can be the instantaneous value or average value of the voltage signal. Secondly, the second voltage value of the load condition is determined by the load condition detection module, which can be the current working state of the load, such as the voltage level corresponding to light load, medium load or heavy load. Then, when both voltage values meet the predetermined conditions, the blanking time parameter adjustment module will adjust the blanking time parameter according to this information.
[0054] Preferably, the predetermined condition may be that the voltage values of the input voltage signal and the load condition are both within a predetermined range. This range may be set according to the design requirements and operating conditions of the circuit. For example, if the voltage value of the input voltage signal is between 8V and 12V, and the voltage value of the load condition is between 3V and 5V, it may be considered that the predetermined condition is met. In this case, the blanking time parameter may be adjusted according to a preset formula, such as blanking time = α × (voltage value of the input voltage signal / reference voltage value)^β, where α and β are coefficients determined according to the load condition. In addition, a self-learning algorithm may be introduced to automatically adjust the values of α and β according to historical data to achieve a better control effect.
[0055] In some embodiments, determining the blanking time parameter according to the input voltage signal and the load condition further comprises:
[0056] determining a first voltage value of an input voltage signal;
[0057] determining a second voltage value for a load condition;
[0058] And when both the first voltage value and the second voltage value satisfy a predetermined condition, adjusting the blanking time parameter.
[0059] It should be noted that this embodiment describes in detail how to determine the blanking time parameters according to the input voltage signal and the load condition. This method allows the circuit to automatically adjust the blanking time under different voltage and load conditions to achieve more efficient power management.
[0060] Specifically, the process of determining the blanking time parameters includes the following steps: First, the first voltage value of the input voltage signal is determined by the voltage signal detection module. This value can be the peak value, effective value or other statistical value of the voltage signal. Secondly, the second voltage value of the load condition is determined by the load condition detection module, and this value can reflect the current state of the load, such as light load, medium load or heavy load. Then, when both voltage values meet the predetermined conditions, the blanking time parameter adjustment module will adjust the blanking time parameters according to this information. The predetermined condition can be that the voltage value is within a specific safety range, for example, the voltage value of the input voltage signal is between 8V and 12V, and the voltage value of the load condition is between 3V and 5V.
[0061] Preferably, the blanking time parameter can be adjusted by an algorithm, which calculates a new blanking time parameter based on the voltage value of the input voltage signal and the load condition. For example, a lookup table can be used to store the optimal blanking time parameters under different voltage and load conditions, or a mathematical model can be used to dynamically calculate the blanking time parameters.
[0062] Furthermore, a feedback mechanism can be introduced to fine-tune the blanking time parameters according to the actual performance of the circuit to achieve more precise control. In order to further improve the flexibility and adaptability of the system, a machine learning algorithm can be used to continuously optimize the calculation model of the blanking time parameters so that it can adapt to more complex and changing working conditions.
[0063] In some embodiments, the predetermined condition is that the voltage values of the input voltage signal and the load condition are both within a predetermined range.
[0064] It should be noted that this embodiment further clarifies how to adjust the blanking time parameters according to the voltage value of the input voltage signal and the load condition, and sets specific predetermined conditions. These conditions ensure that the blanking time parameters are adjusted within a safe voltage range.
[0065] Specifically, the predetermined condition means that the voltage values of the input voltage signal and the load condition must be within a preset safety range. For example, the safety range of the input voltage signal may be set to 8V to 12V, and the safety range of the load condition may be set to 3V to 5V. These ranges can be determined according to the requirements of the circuit design and the actual working conditions. When the voltage values of the input voltage signal and the load condition are both within their respective safety ranges, the blanking time parameter adjustment module adjusts the blanking time parameters according to this information.
[0066] Preferably, in order to ensure the stability and safety of the circuit, a threshold detection mechanism can be set. When the voltage value exceeds a preset safety range, the system will automatically enter a protection mode to prevent the circuit from being damaged.
[0067] Furthermore, a real-time monitoring system can be introduced to continuously track changes in voltage signals and load conditions to ensure that the blanking time parameters are always adjusted based on the latest data. In order to improve the response speed and accuracy of the system, a high-speed analog-to-digital converter ADC can be used to obtain the voltage signal, and an efficient algorithm can be used to quickly calculate the blanking time parameters.
[0068] In some embodiments, the leading edge blanking time of the control circuit corresponds to the value of the blanking time parameter.
[0069] It should be noted that this embodiment describes how to link the adjustment of the blanking time parameter with the leading edge blanking time control of the circuit. By ensuring that the leading edge blanking time corresponds to the value of the blanking time parameter, the response time of the circuit can be accurately controlled, thereby improving the performance of the circuit.
[0070] Specifically, the leading edge blanking time refers to the delay time before the circuit starts to respond after receiving the input signal. Control of this time is crucial for the fast response of the circuit. The value of the blanking time parameter can be determined by an algorithm that takes into account the input voltage signal and the load condition and calculates the appropriate leading edge blanking time. For example, the algorithm may calculate the blanking time parameter based on the voltage value of the input voltage signal and the voltage value of the load condition through a mathematical model.
[0071] Preferably, in order to achieve more precise control, a closed-loop control system can be used to dynamically adjust the leading edge blanking time. In this system, the value of the blanking time parameter is adjusted in real time according to the actual performance of the circuit. For example, if the response speed of the circuit is not fast enough, the system will automatically increase the value of the blanking time parameter to reduce the leading edge blanking time.
[0072] Furthermore, a prediction model can be introduced to predict future voltage and load changes based on historical data, so as to adjust the blanking time parameters in advance to adapt to the upcoming changes. This method can improve the adaptability and response speed of the circuit.
[0073] In some embodiments, the blanking time parameter is determined by the following formula:
[0074]
[0075] in, is the blanking time, is the voltage value of the input voltage signal, is the reference voltage value, and is a coefficient determined according to the load conditions.
[0076] It should be noted that this embodiment describes in detail how to determine the blanking time parameter by a specific mathematical formula. This method allows the circuit to dynamically adjust the blanking time according to the voltage value of the input voltage signal and the load condition to achieve more precise control.
[0077] Specifically, the blanking time parameter can be determined by the following formula:
[0078]
[0079] in, Indicates the blanking time, is the voltage value of the input voltage signal, is the reference voltage value, and These coefficients can be set according to the circuit design and load characteristics to ensure that the blanking time parameters can adapt to different working conditions.
[0080] Preferably, in order to improve the flexibility and accuracy of control, an adaptive algorithm can be used to dynamically adjust the coefficients and For example, these coefficients can be adjusted based on the historical data of the load and the changing trend of the input voltage signal. In addition, a feedback mechanism can be introduced to fine-tune these coefficients according to the actual performance of the circuit to achieve a better control effect. For example, if it is detected that the standby power consumption of the circuit is too high, the system can automatically increase To reduce the blanking time, the system can automatically increase the power consumption if the power consumption is too high when the load is detected. value to increase the blanking time and thus improve the circuit's load capacity.
[0081] In some embodiments, the optimal value of the blanking time parameter is solved by the following formula:
[0082]
[0083] in, is the standby power consumption, is the power consumption when loaded.
[0084] It should be noted that this embodiment describes how to solve the optimal value of the blanking time parameter through a specific mathematical formula. This method allows the circuit to optimize power consumption under different working conditions, thereby improving the efficiency of power management.
[0085] Specifically, the optimal value of the blanking time parameter can be solved by the following formula:
[0086]
[0087] in, represents the optimal value of the blanking time parameter, Indicates the standby power consumption, Indicates the power consumption when loaded. By adjusting the blanking time parameter, the optimal value that minimizes the total power consumption can be found.
[0088] Preferably, in order to achieve more accurate power consumption control, a more complex mathematical model can be used to solve the optimal value of the blanking time parameter. For example, a nonlinear optimization algorithm can be introduced to consider more circuit parameters and working conditions to find a more accurate optimal blanking time parameter.
[0089] Furthermore, a machine learning method can be used to learn the optimal blanking time parameters under different conditions through training data sets, thereby achieving adaptive power consumption management. This method can further improve the energy efficiency and response speed of the circuit.
[0090] In some embodiments, the input voltage signal includes a direct current voltage or an alternating current voltage;
[0091] The load conditions include light load, medium load or heavy load.
[0092] It should be noted that this embodiment involves the diversity of input voltage signals and the classification of load conditions to adapt to different power management requirements. By considering DC voltage or AC voltage and different load conditions, the circuit can more flexibly cope with various working conditions.
[0093] Specifically, the input voltage signal can be a DC voltage or an AC voltage, depending on the application scenario and design requirements of the circuit. The load condition can be a light load, a medium load, or a heavy load, and these classifications can be defined based on the actual power consumption and the working state of the circuit. For example, a light load may refer to a standby state, a medium load may refer to a normal working state, and a heavy load may refer to a high power output state.
[0094] Preferably, in order to better adapt to different input voltage and load conditions, an intelligent detection system can be designed to monitor the type of input voltage and the state of load in real time. This system can include a voltage detection sensor and a load detection circuit, which can provide accurate voltage and load information.
[0095] Furthermore, a multi-mode control strategy can be adopted to automatically switch control parameters according to different input voltage and load conditions to achieve the best power management effect. For example, when AC voltage input is detected, the system can automatically adjust the blanking time parameters to adapt to the characteristics of AC voltage; when heavy load is detected, the system can increase the blanking time to ensure stable output of the circuit.
[0096] The above-mentioned embodiments of the present invention have the following beneficial effects: the adaptive blanking timing circuit control method of the present invention can provide a flexible power management strategy, by dynamically adjusting the blanking time parameters according to the input voltage signal and the load condition, optimizing the circuit's load capacity and standby power consumption. This method can ensure that the circuit can maintain high efficiency and stability under different working conditions, while reducing the power consumption caused by voltage fluctuations or load changes, and improving the overall energy efficiency of the power supply system.
[0097] In addition, the control method of the present invention can also improve the response speed and adaptability of the power supply circuit by accurately controlling the leading edge blanking time of the circuit. By constructing an adaptive blanking timing circuit model and adjusting the blanking time parameters in real time according to the feedback signal, the method can effectively reduce the power consumption of the circuit in different working states, especially in the standby state. This method further improves the stability and efficiency of the circuit by determining the voltage value of the input voltage signal and the load condition and adjusting the blanking time parameters when the predetermined conditions are met.

The blanking time control module can adopt a higher performance processor to achieve faster response speed. In addition, a user interface can be introduced to allow the user to manually adjust the blanking time parameters as needed to adapt to specific application requirements.
