1Use of energy by moving object
If voltage regulator adjusts voltage based on system parameters using lookup tables, then power delivery efficiency is improved, but device complexity increases
Solution Approach 1:
The patent pre-calculates and stores optimal voltage mappings in lookup tables during system configuration or initialization. These tables map system parameters (like power demand levels) to optimal input and output voltage values. During operation, the voltage regulator simply queries these pre-computed tables rather than performing complex real-time optimization calculations, thus improving efficiency while keeping the runtime device complexity manageable.
Solution Approach 2:
The lookup tables serve as an intermediary data structure between the system parameters and the voltage regulation logic. Instead of directly computing optimal voltages from parameters, the system uses the tables as a mediator that has already performed the complex mapping relationship, simplifying the real-time control while maintaining optimization benefits.
2Adaptability or versatility
If multiple voltage values are maintained for different system parameters, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent maintains multiple voltage values in the lookup tables corresponding to different system parameters such as power demand levels, thermal conditions, and load types. By changing the voltage parameters based on the current system state and querying the appropriate table entries, the system achieves high adaptability to varying operating conditions without requiring complex real-time decision logic.
