Engineering Contradiction Analysis
1Reliability
If resistors are connected in parallel on output terminals to reduce voltage, then voltage offset is reduced, but power supply efficiency deteriorates due to power loss
Solution Approach 1:
The patent replaces the passive resistor-based voltage reduction mechanism with an active DC-to-DC converting unit that can dynamically adjust output voltages. This substitution transforms the system from passive energy dissipation to active energy conversion, significantly reducing power loss while maintaining voltage regulation capability.
Solution Approach 2:
The patent changes the operating parameters by introducing a regulating circuit that can dynamically adjust the conversion ratio of the DC-to-DC converter. This allows the system to adaptively change output voltages based on load conditions, optimizing both voltage regulation and power efficiency under different operating scenarios.
2Reliability
If passive circuit architecture is used to reduce voltage on output terminals, then voltage offset is reduced, but the ability to correspondingly adjust output voltages deteriorates
Solution Approach 1:
The patent replaces the fixed passive circuit architecture with a controllable active DC-to-DC converting unit. This substitution enables dynamic voltage adjustment capability while maintaining offset reduction, as the converter can be controlled to provide different output voltages based on system requirements.
Solution Approach 2:
The patent introduces dynamic control capability through the regulating circuit that can adjust the DC-to-DC conversion parameters in real-time. This transforms the static passive voltage reduction into a dynamic active regulation system, enabling the system to adaptively respond to changing load conditions and maintain optimal voltage levels.

AI summary
A power supply apparatus including a multi-outputs power supply circuit and a first regulating circuit is provided. The multi-outputs power supply circuit has a plurality of output terminals. The multi-outputs power supply circuit provides a first voltage from one output terminal among the output terminals and provides a second voltage from another one output terminal among the output terminals, where a rated voltage value of the first voltage is greater than a rated voltage value of the second voltage. The first regulating circuit is coupled between the one output terminal and the another one output terminal, where the first regulating circuit is enabled when the first voltage exceeds a first threshold, and begins to regulate the second voltage after being enabled.
