Engineering Contradiction Analysis
1Stability of the object's composition
If a capacitor type booster is used, then the output voltage is more stable, but the voltage increase is slower
Solution Approach 1:
The patent combines a capacitor type booster and an inductor type booster in parallel within the same power conversion system. The controller selectively activates either the capacitor type booster or the inductor type booster based on system requirements, allowing the system to achieve both stable output voltage and rapid voltage increase capability.
2Productivity
If an inductor type booster is used, then the output current is greater and voltage increases rapidly, but the output voltage is more unstable
Solution Approach 1:
The patent combines a capacitor type booster and an inductor type booster in parallel within the same power conversion system. The controller selectively activates either the capacitor type booster or the inductor type booster based on system requirements, allowing the system to achieve both stable output voltage and rapid voltage increase capability.
Solution Approach 2:
The patent implements dynamic control by using a controller to selectively switch between the capacitor type booster and the inductor type booster based on real-time system requirements. This dynamic switching allows the system to adapt its characteristics - using the inductor type booster when rapid voltage increase is needed and the capacitor type booster when stable output voltage is prioritized.
