Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If regulator parameters are continuously tuned to maintain optimal performance, then performance optimization is improved, but energy consumption increases
Solution Approach 1:
The system implements periodic parameter updates at predetermined time intervals rather than continuous tuning. The regulator parameter update unit updates the regulator parameter only at these specific intervals, allowing the system to maintain optimal performance while significantly reducing the energy consumption associated with continuous parameter adjustment and monitoring.
2Adaptability or versatility
If regulator parameters are updated frequently to adapt to component aging, then adaptability is improved, but productivity decreases due to operation interruptions
Solution Approach 1:
The system performs parameter updates at predetermined time intervals before significant performance degradation occurs. By proactively updating the regulator parameter at scheduled intervals, the system adapts to component aging effects before they impact power conversion performance, eliminating the need for reactive interruptions to maintain productivity.
Solution Approach 2:
The power conversion operation continues uninterrupted while the regulator parameter is updated at predetermined intervals. The update mechanism is designed to work seamlessly within the ongoing conversion operation, ensuring that the useful action of power conversion remains continuous without being interrupted by parameter adjustment procedures.
3Manufacturing precision
If manual tuning of regulator parameters is performed to optimize performance, then manufacturing precision is improved, but ease of operation deteriorates
Solution Approach 1:
The regulator parameter update unit automatically updates the regulator parameter based on predetermined time intervals and performance data, eliminating the need for manual tuning operations. The system serves itself by autonomously adjusting parameters to maintain optimal performance, thereby improving ease of operation while preserving the precision that would otherwise require skilled manual intervention.
Solution Approach 2:
The system uses performance feedback from the power conversion operation to automatically adjust the regulator parameter. The regulator parameter update unit receives feedback information and uses it to determine appropriate parameter updates, replacing manual tuning with an automated feedback-driven adjustment mechanism that maintains precision while simplifying operation.

AI summary
An electric switch-mode power converter comprises: a parameter predictor for predicting and updating at least one regulator parameter of a regulator controlling a switching device of the converter, a performance feedback signal generator for providing a performance feedback signal indicative of a performance of the conversion operation, wherein the parameter predictor is configured to predict an update of the regulator parameter based on the performance feedback signal and during update intervals, the intervals being during the power conversion operation and being separated by pauses without update.
