Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the photovoltaic panel is connected directly to the tank module through a switching device, then the device complexity is reduced, but the solar energy efficiency and charging efficiency deteriorate
Solution Approach 1:
The circuit is divided into multiple process modules (first process module and second process modules) that operate in parallel. Each module independently processes current from the photovoltaic panel, allowing the system to maximize power extraction while maintaining manageable complexity through modular architecture
Solution Approach 2:
The patent implements dynamic current modulation through control modules that adjust the operation of process modules based on real-time conditions. The interlaced operation of parallel modules allows dynamic optimization of power transfer efficiency while adapting to varying solar input and battery charging requirements
2Productivity
If multiple process modules are used to maximize power output, then the solar energy efficiency is improved, but the device complexity increases
Solution Approach 1:
The system uses multiple process modules (first process module and second process modules) that can operate in parallel to process current from different photovoltaic panels or different portions of the same panel, enabling maximum power point tracking and improved overall efficiency
Solution Approach 2:
Multiple process modules are combined in a parallel architecture where they share common control logic and output stages. This merging approach allows the system to achieve high power output efficiency while managing complexity through standardized, reusable module designs
3Productivity
If the control module manages all current flow to optimize charging, then the charging efficiency is improved, but the risk of control module damage from excessive power increases
Solution Approach 1:
The current management function is segmented across multiple process modules that operate in parallel. Each process module handles a portion of the total current, distributing the power management burden and reducing the risk to any single control element while maintaining efficient charging throughput
Solution Approach 2:
Process modules serve as intermediary components between the photovoltaic panels and the tank module. These intermediaries perform current modulation and protection functions, shielding the main control module from excessive power conditions while enabling optimized charging control

AI summary
A photovoltaic circuit configured to supply an output current to a tank module is provided. The photovoltaic circuit comprises a photovoltaic transformation module, a first process module, a plurality of second process modules, and a first control module. The process modules are connected to each other in parallel. The process modules in the parallel connection are connected to the photovoltaic transformation module and the tank module in series. The first control module is connected to the first process module and generates a control signal to the process modules in response to a divided current, a modulation current, and a last output current generated by the first process module. Thereby, the process modules interlacedly output the corresponding modulation current as the output current supplied to the energy reserve module.
