Engineering Contradiction Analysis
1Power
If larger capacitors or additional buffer capacitors are used to meet peak power requirements, then the power supply capability is improved, but the device size and cost increase
Solution Approach 1:
The energy storage function is segmented between two distinct components: a first energy storage element for bulk energy storage and a second energy storage element for peak power delivery. This segmentation allows each component to be optimized for its specific function, reducing the total volume required compared to using a single large capacitor for both purposes.
Solution Approach 2:
The first boost circuit acts as an intermediary between the first energy storage element and the second energy storage element. It transfers energy from the first energy storage element to the second energy storage element during normal operation, enabling the second energy storage element to maintain sufficient charge to meet peak power demands without requiring excessive capacitance.

3Adaptability or versatility
If the power conversion system dynamically adjusts to meet varying power requirements, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The system dynamically switches between two operational modes based on real-time voltage level detection. The control circuit monitors the voltage across the first energy storage element and automatically transitions between boost mode and direct transfer mode, providing adaptive response to varying power demands without requiring complex continuous control algorithms.
Solution Approach 2:
The detection circuit provides real-time feedback on the voltage level of the first energy storage element to the control circuit. This feedback mechanism enables the control circuit to make informed decisions about when to activate the boost circuit versus when to use direct energy transfer, achieving dynamic adaptability through simple threshold-based control.

AI summary
The present disclosure relates to a power conversion system. A first boosting circuit of the power conversion system is coupled between a first energy storage element and a second energy storage element. A switching element of the power conversion system is coupled to the first boost circuit in parallel. When the first voltage value is lower than a first preset level, the control circuit turns off the switching element and drives the first booster circuit to maintain a second voltage value according to the first voltage value, so that the power conversion system operates in a first state. When the first voltage value is equal to or larger than the first preset level, the control circuit turns on the switching element and turns off the first boost circuit, so that the power conversion system operates in a second state.
