Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a power supply delivers pulsed power with high voltage and current amplitudes, then the power delivery capability is improved, but the system complexity increases
Solution Approach 1:
The system is divided into modular components including energy storage modules (supercapacitors and batteries), converter modules (DAB and DC-DC converters), and control modules. Each module performs a specific function and can be independently managed, allowing high power delivery while maintaining manageable system complexity through modular architecture.
Solution Approach 2:
A dual-active-bridge (DAB) converter is introduced as an intermediary component between the energy storage system and the pulsed power load. The DAB converter facilitates bidirectional energy transfer and galvanic isolation, enabling efficient power delivery while simplifying the control of the overall system.
2Adaptability or versatility
If the system adapts to individual entity characteristics and system statuses, then the adaptability is improved, but the control complexity increases
Solution Approach 1:
The control system dynamically adjusts energy distribution based on real-time entity characteristics and system status. The controller monitors voltage, current, and energy levels, and automatically reconfigures the energy storage and conversion components to optimize performance for different load requirements, achieving adaptability through dynamic control strategies.
Solution Approach 2:
The system incorporates feedback mechanisms where the controller continuously monitors system parameters (voltage, current, energy levels) and entity characteristics, then adjusts the operation of converters and energy storage components accordingly. This closed-loop control enables the system to adapt to changing conditions while maintaining manageable control complexity through automated feedback-based adjustment.
3Power
If energy is compressed in time and space for pulsed power delivery, then the power density is improved, but the energy management complexity increases
Solution Approach 1:
Energy is pre-stored in supercapacitors and batteries before the pulsed power demand occurs. The system charges the energy storage components during off-periods, allowing rapid energy delivery when needed without requiring continuous high-power generation, thus achieving high power density while simplifying energy management through advance energy preparation.
Solution Approach 2:
The system operates in periodic cycles of charging and discharging energy storage components. During non-pulse periods, energy is accumulated in the supercapacitors and batteries; during pulse periods, energy is rapidly delivered to the load. This periodic operation pattern enables high power density delivery while managing energy storage and conversion in a systematic, controllable manner.
