Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a high-voltage capacitor is used as the storage capacitor, then the SMPS can store and release energy effectively, but the control scheme becomes fixed and cannot adapt to low-voltage capacitor configurations
Solution Approach 1:
The patent implements dynamic adaptability by detecting the capacitor type (high-voltage or low-voltage) and automatically switching between different control schemes. The controller dynamically adjusts its operation mode based on the connected capacitor, enabling the SMPS to maintain reliable energy storage and release functionality across different capacitor configurations without requiring manual reconfiguration or separate control circuits.
2Ease of manufacture
If a low-voltage capacitor is used as the storage capacitor, then the SMPS can operate with lower voltage components, but the traditional control scheme becomes inapplicable and requires redesign
Solution Approach 1:
The patent creates a universal control scheme that can handle both high-voltage and low-voltage capacitor configurations within a single SMPS design. The controller incorporates multiple control modes (boost control for high-voltage capacitors, buck control for low-voltage capacitors) and automatically selects the appropriate mode based on capacitor detection, eliminating the need for separate control circuits for different capacitor types and simplifying manufacturing.
3Adaptability or versatility
If the SMPS is designed to support both high-voltage and low-voltage capacitor configurations, then versatility is improved, but the control system complexity increases
Solution Approach 1:
The patent reduces control system complexity through dynamic adaptation and automatic mode switching. The controller detects the capacitor type and automatically selects the appropriate control scheme (boost or buck mode) without requiring complex manual configuration or multiple independent control circuits. This dynamic approach maintains versatility while minimizing the actual operational complexity at any given time.
Solution Approach 2:
The controller performs self-configuration by automatically detecting the capacitor type and adjusting its control parameters accordingly. The system eliminates the need for external configuration or manual intervention, making the complexity management automatic and transparent to the user while still supporting multiple capacitor configurations.

AI summary
A switch mode power supply (SMPS) with control scheme selection for high-voltage configuration and low-voltage configuration of the SMPS. The SMPS operates in at least a charge state or a release state. The SMPS has a mode control module receiving a mode setting signal indicative of the configuration of the SMPS and a state indication signal indicative of the state of the SMPS. The SMPS selects a boost control module or a buck control module to control the SMPS according to the mode setting signal and the state indication signal.
