[0061] Example
[0062] See also Figure 1 The present invention provides a technical solution: a charging module input voltage system for a mining charger includes:
[0063] The voltage adaptation control module uses a microcontroller (MCU) to measure and calculate real-time load demand based on current load current and voltage data, automatically adjusts the transformer output voltage, and continuously adjusts the power conversion rate according to the voltage feedback signal to optimize the voltage output of the next stage and obtain the adjusted voltage state;
[0064] The rectification and filtering module performs digital filtering and waveform reconstruction based on the adjusted voltage state. By analyzing the current current waveform, the performance parameters of the filter capacitor are calculated and adjusted, and the waveform characteristics are matched to obtain waveform smoothing output information.
[0065] The voltage and current regulation module analyzes the charging standards of various mining equipment based on waveform smoothing output information, dynamically adjusts the current and voltage parameters of the charging interface by programming the microcontroller to control the electronic switch (referring to transistors such as MOSFET, IGBT, etc.), determines the optimal voltage and current output configuration, and obtains the charging interface control parameters;
[0066] The charging system monitoring module predicts the power demand of mining equipment based on the charging interface control parameters, automatically monitors the voltage and current status, adjusts the charger output voltage in real time to maintain the optimal voltage and current status, and monitors the operating status of the charger to obtain power management records.
[0067] The adjusted voltage state specifically includes voltage stability, voltage output accuracy, and response speed. The waveform smoothing output information includes noise level, harmonic reduction information, and stability enhancement results. The charging interface control parameters include output configuration, adjustment sensitivity, and safety limits. The power management records include event logs, efficiency data, and maintenance reminder information.
[0068] See also Figure 2 , the steps for automatically adjusting the transformer output voltage are as follows:
[0069] Use the microcontroller to collect current load current and voltage data, measure and calculate real-time load demand, and determine voltage adjustment requirement information;
[0070] The instantaneous values of current and voltage are continuously collected by current sensors and voltage sensors installed in the load circuit. The data collection frequency is set to once per second to ensure that the dynamic change trends of current and voltage can be accurately captured. The collected signals are converted into digital signals by the analog-to-digital converter (ADC) and then transmitted to the microcontroller memory unit. The microcontroller calls the internal data analysis module to perform peak detection, instantaneous value screening and data correction on the values collected every second. The correction algorithm performs zero point adjustment and proportional factor correction based on the sensor calibration parameters to eliminate the interference of errors on the data. For the obtained correction data, the microcontroller uses a recursive method to calculate the average current demand value within one minute, and calls the reference voltage data to calculate the instantaneous voltage deviation. The voltage deviation value is obtained by subtracting the instantaneous value of the current voltage from the reference voltage. The maximum value of all deviation values is extracted as the key voltage deviation. This information is used to further judge the voltage adjustment requirements.
[0071] Based on the voltage adjustment demand information, the output voltage of the transformer is automatically adjusted using the formula:
[0072] ;
[0073] Match the real-time load demand and get the adjusted transformer state, where: Represents the adjusted output voltage, which is the voltage provided to the load after the transformer adjusts. is the current input voltage of the transformer, the original voltage entering the transformer, and the reference value of the adjustment process. is the voltage deviation, which indicates the difference between the current voltage and the target voltage. It is the voltage amount that needs to be adjusted. The average current demand is the current demand, which is calculated based on the average value of the load current over a period of time. It is the voltage regulation coefficient, which is used to adjust the influence of voltage deviation on output voltage. is the current influence coefficient, which indicates the strength of the current demand in voltage regulation and is used to adjust the impact of current changes on the output voltage;
[0074] The following data was collected: the current transformer input voltage Volts, voltage regulation factor , Volts, indicating that the current voltage needs to be adjusted down by 5 volts to match the safe operating voltage of the device. The current influence coefficient indicates the sensitivity of current changes to voltage adjustments, Amperes, the current demand, plug the value into the formula:
[0075] ;
[0076] The results show that through real-time adjustment of voltage and current, it is possible to ensure that the power supply operates at a safer and more efficient voltage level, so that the system can meet current power needs while protecting equipment.
[0077] See also Figure 3 , the specific steps for obtaining the adjusted voltage state are:
[0078] Receive the voltage feedback signal from the transformer, monitor the output voltage in real time, and calculate the deviation from the target voltage to obtain the current voltage deviation information;
[0079] The voltage sensor array is used to collect data at the output end of the transformer. The sensor can continuously monitor the voltage fluctuation data and transmit the data to the microcontroller through the digital signal interface. The microcontroller decodes the received signal and extracts the actual voltage value and fluctuation range. The information is compared with the set target voltage parameters in real time, and the current voltage deviation information is obtained by calculating the difference between the two. The microcontroller uses the target voltage as a reference value, and cyclically accumulates and compares the voltage data collected each time, and finally generates an output data stream containing the voltage deviation result.
[0080] Based on the current voltage deviation information, the microcontroller is used to adjust the power conversion rate using the formula:
[0081] ;
[0082] Optimizing the voltage output of the next stage , get the adjusted voltage state, where, is the currently monitored output voltage, is the voltage deviation, is the adjustment factor, which determines the effect of the deviation adjustment on the output voltage;
[0083] By dynamically adjusting the voltage to respond to voltage deviations, we can effectively match load requirements, reduce energy consumption and increase overall efficiency. The following data are monitored: Volts, the currently monitored output voltage, Volt, voltage deviation, means the current voltage is lower than the target voltage, Adjustment coefficient, the value is based on historical data analysis and response requirements, and the voltage output of the next stage is calculated using the parameters:
[0084] ;
[0085] The results show that through subtle adjustments, the system can quickly respond to voltage changes, maintain the stability of voltage output, and ensure that load demand is met. It also shows the accuracy and response speed of system adjustments, which plays an important role in maintaining equipment safety and energy efficiency.
[0086] See also Figure 4 , the specific steps for adjusting the performance parameters of the filter capacitor are:
[0087] Based on the adjusted voltage state, digital filtering and waveform reconstruction are performed to collect current peak and fundamental frequency data to obtain a current waveform characteristic set;

The collected signals include the instantaneous value of the current and the waveform change characteristics. The signal data is first preprocessed to eliminate external interference sources, such as high-frequency noise or DC offset. Then, digital filtering technology is used to extract the key characteristics of the waveform, such as fundamental frequency components, harmonic components and transient fluctuations. The data is normalized to ensure that the waveform data of different sampling nodes can be uniformly standardized for analysis. After normalization, the current waveform is reconstructed in combination with Fourier transform. The peak current and fundamental frequency data are further extracted through the reconstructed waveform, and the analysis results are organized into a set of current waveform characteristic sets.
[0089] Based on the current waveform characteristic set, the theoretical capacitance value and withstand voltage index of the filter capacitor are calculated using the formula:

It is the voltage corresponding to the current peak, and is the voltage reading when the current reaches its peak. It is a new withstand voltage index, which is the highest voltage that the capacitor should be able to withstand after adjustment;

[0098] Calculate the withstand voltage index:
[0099] ;
[0100] ;
[0101] The results show that the calculated capacitance value of the filter capacitor is 0.0745F and the withstand voltage value is 19V, which meets the performance requirements of the current waveform characteristic set and can be used for adjusting the configuration of the performance parameters of the filter capacitor.
[0102] Adjust the performance parameters of the filter capacitor or replace it based on the performance parameter adjustment configuration, and verify the effect of the capacitor adjustment to obtain the adjusted filter capacitor;

If the capacitance or withstand voltage of the existing capacitor does not meet the requirements, select a capacitor model that meets the calculated value for replacement. At the same time, install the adjusted or replaced capacitor into the actual circuit. After the installation is completed, collect the current waveform data of the adjusted circuit through current waveform monitoring, compare and analyze the new waveform data with the theoretical calculated value to verify whether the adjustment or replacement operation is correct, and finally record the adjustment status of the capacitor.

The correction operation is completed by adjusting the characteristic parameters of the filter capacitor, and finally generate preliminary waveform matching information for the next step of analysis and optimization.
[0107] Based on the preliminary waveform matching information, the waveform processing parameters are adjusted using Fourier transform, including adjusting the threshold and filter coefficient, and the current waveform is continuously optimized to obtain waveform smoothing output information;
[0108] The waveform processing parameters are adjusted using Fourier transform. The Fourier transform step includes converting the time domain characteristics of the current waveform into frequency domain characteristics, and extracting the corresponding amplitude and phase information in the spectrum. The distribution of frequency components is used to analyze the optimization requirements of the filter parameters. By adjusting the threshold and coefficient of the filter, the filtering characteristics in the frequency domain are re-optimized to eliminate high-frequency components or low-frequency noise. Finally, a new filter configuration is generated. This configuration is applied to the current waveform for continuous optimization to obtain waveform smoothing output information to ensure that the current waveform meets the matching requirements.
