Innovation Solution
Implementing a power circuit with a time-slice power-on and power-off mechanism, where the power supply voltage slowly increases or decreases during switching, using a power module and a power feeding module with delay units and current/voltage sources to control the static operating current, reducing the impact on the power supply and improving stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the power circuit is switched on or off quickly, then the switching speed is improved, but the voltage fluctuation of the power supply increases and component aging accelerates
Solution Approach 1:
The patent applies preliminary action by gradually increasing the power supply voltage before full power operation through a soft-start mechanism. The power feeding module controls the static operating current to ramp up slowly, preventing sudden voltage fluctuations that would cause component stress and aging, thus improving reliability while maintaining acceptable switching speed.
Solution Approach 2:
The patent implements dynamics by making the power supply voltage change dynamically during switching transitions. The power feeding module adjusts the static operating current in real-time based on the switching state, creating a controlled voltage ramp-up and ramp-down profile that reduces voltage fluctuations and component stress, thereby improving reliability without completely sacrificing switching speed.
2Productivity
If the power circuit is switched on or off quickly, then the switching efficiency is improved, but the voltage fluctuation of the power supply increases
Solution Approach 1:
The patent applies preliminary action by pre-charging the power supply voltage through the power feeding module before the power circuit reaches full power. This gradual voltage buildup prevents sudden draws that cause voltage fluctuations, maintaining power supply stability while achieving efficient switching through controlled transitions.
Solution Approach 2:
The patent introduces the power feeding module as an intermediary between the power supply and the power circuit. This intermediary controls the static operating current to gradually establish the power supply voltage, acting as a buffer that prevents direct sudden changes and voltage fluctuations, thereby maintaining stability while enabling efficient switching operation.
3Stability of the object's composition
If the power supply voltage increases slowly during switching on, then the stability of the power supply is improved, but the switching time increases
Solution Approach 1:
The patent applies preliminary action by implementing a controlled soft-start sequence where the power feeding module gradually increases the static operating current to establish the power supply voltage. This preliminary gradual buildup ensures stability by preventing sudden voltage changes, while the controlled nature of the ramp-up minimizes the time penalty compared to uncontrolled switching.
Solution Approach 2:
The patent implements dynamics by making the voltage increase rate adjustable through the power feeding module's control of the static operating current. The system dynamically balances the ramp-up speed to achieve sufficient stability while minimizing switching time, optimizing the trade-off between these two parameters through active control rather than fixed behavior.
