Engineering Contradiction Analysis
1Loss of energy
If conventional power supply structure and components are used, then power efficiency is improved to some extent, but the output voltage cannot be automatically adjusted for different electronic products, so overall efficiency cannot be further improved
Solution Approach 1:
The power supply system dynamically adjusts the output voltage based on real-time detection of input power and stored data. The control module continuously monitors the relationship between output voltage and input power, automatically changing the voltage level to find the optimal operating point that minimizes input power consumption for the current output requirement.
Solution Approach 2:
The system implements a feedback mechanism where the control module detects input voltage and input current values, calculates input power, and uses this information to adjust the output voltage. The control module stores the relationship between output voltage values and corresponding input power values, and uses this stored data to make intelligent voltage adjustment decisions.
2Device complexity
If output voltage is manually fixed for different electronic products, then device complexity is reduced, but the overall efficiency of the power supply cannot be further improved
Solution Approach 1:
The power supply system performs self-optimization by automatically detecting input power consumption at different output voltage levels and selecting the voltage that minimizes power consumption. The control module independently makes voltage adjustment decisions based on stored data without requiring external intervention, enabling the system to self-optimize its efficiency.
Solution Approach 2:
The system changes the output voltage parameter dynamically based on detected input power consumption patterns. By varying the output voltage within a range and storing the corresponding input power values, the system identifies and maintains the optimal voltage parameter that achieves minimum input power consumption for given output requirements.

AI summary
A smart power supply system is provided. An input end connecting to a power supply provides power to a control module, so that the control module can receive an application voltage range from an electronic product, and then control a power module according to the application voltage range to make an output voltage value of an output end increased gradually according to the application voltage range from low to high. In the process that the output voltage value of the output end is increased gradually, the control module detects an input voltage value and an input current value and the output voltage value to calculate and store an input power correspondingly, and then control the power module according to the output voltage value, which corresponds to the minimum input power of the stored input powers to make the output voltage value of the output end be an optimum voltage value.
