Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple analog converters are used to meet varied voltage requirements, then voltage conversion capability is improved, but device complexity increases
Solution Approach 1:
The patent employs a universal digital DC/DC converter that can be configured to output multiple different voltages through software control rather than requiring separate analog converters for each voltage level. This multi-functional approach allows a single converter to replace multiple specialized converters, reducing overall system complexity while maintaining the ability to provide various voltage requirements.
Solution Approach 2:
The patent utilizes digital control to dynamically change the output voltage parameters of the DC/DC converter based on system requirements. By changing control parameters through software rather than hardware reconfiguration, the system can adapt to different voltage needs without adding physical converter components, thereby simplifying the power supply structure.
2Power
If analog DC/DC converters are used for voltage conversion, then voltage conversion is achieved, but monitoring capability deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the microcontroller continuously monitors the output voltage of the DC/DC converter and adjusts control parameters accordingly. This closed-loop feedback system ensures real-time monitoring of power supply status, enabling the system to detect and respond to overvoltage conditions, thereby improving reliability while maintaining voltage conversion capability.
Solution Approach 2:
The patent introduces a microcontroller as an intermediary between the DC/DC converter and the monitoring system. This intermediary component provides the monitoring capability that analog converters lack, allowing the system to achieve both voltage conversion and effective monitoring functions through the coordinating role of the microcontroller.
3Ease of operation
If sequence control chip is added for current sequence requirements, then sequence control capability is improved, but device complexity increases
Solution Approach 1:
The patent merges the sequence control function with the microcontroller that already exists for monitoring and voltage regulation. By combining multiple control functions (monitoring, voltage regulation, and sequence control) into a single microcontroller unit, the system achieves sequence control capability without adding separate control chips, thereby avoiding increased device complexity.
Solution Approach 2:
The microcontroller is designed to perform multiple functions including voltage monitoring, voltage regulation control, and sequence control of power supply currents. This multi-functional approach allows a single component to replace what would traditionally require multiple specialized chips, simplifying the overall control structure while maintaining comprehensive control capability.

AI summary
A single-board power supply structure and a method for providing a power supply are provided. An operational processor sends control signals capable of controlling the output of the power supply to a DC/DC converter. The DC/DC converter converts a received bus voltage into a required power supply voltage according to the received control signals. The operational processor may further monitor the output of the power supply and report the monitored result to a connected upper-layer machine, and may also control the sequence of a plurality of the outputs of the power supply converted by the DC/DC converter by controlling the time for sending the control signals. The structure and the method provided by the present invention can both uniformly, timely, and effectively monitor the output of the single-board power supply.
