Core Design Contradiction:

Loss of energyVSDevice complexity

Solution Approach 1:

The patent segments the power conversion function into multiple capacitors (first capacitor and second capacitor) that can be independently configured to charge at different voltage levels. This segmentation allows the system to handle multiple voltage levels while maintaining manageable circuit complexity through modular capacitor configuration.

Inventive Principle:

Solution Approach 2:

The patent dynamically configures the capacitors based on the input voltage level detected. When input voltage is at the first level, capacitors charge accordingly; when at the second level, they charge differently. This dynamic adaptation optimizes power efficiency while the control logic manages complexity by responding to voltage conditions rather than requiring fixed complex circuitry.
