Single-Converter Power Shutdown for Output and Auxiliary Rails
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power systems with separate power converters for output and auxiliary power face increased costs and space limitations, and can disrupt the power down sequence, leading to issues with fault logging and data integrity.
Innovation Solution
A power system with a single power converter that provides both output and auxiliary power, managed by a controller that interrupts power based on thresholds to maintain a proper power down sequence, eliminating the need for an additional converter and ensuring reliable data logging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate power converters are used for output power and auxiliary power, then power conversion functions are provided, but system size and cost increase
Solution Approach 1:
The patent combines the output power converter and auxiliary power converter into a single integrated power converter. The controller manages both output power and auxiliary power conversion functions within one converter unit, eliminating the need for separate converters and reducing overall system size while maintaining both power conversion capabilities
Solution Approach 2:
The single power converter is designed to perform multiple functions: it can convert power for the main output and simultaneously provide auxiliary power conversion. The controller dynamically allocates the converter's capacity between output power and auxiliary power based on system needs, making the converter a universal power conversion solution
2Adaptability or versatility
If separate power converters are used for output power and auxiliary power, then power conversion is provided, but device complexity increases
Solution Approach 1:
The patent merges two separate power converters into one integrated unit. The single converter includes control circuitry that manages both output power conversion and auxiliary power conversion, reducing the number of discrete components and simplifying the overall device architecture
Solution Approach 2:
The integrated power converter is designed as a multi-functional device that can operate in different modes: providing full output power, providing auxiliary power, or operating in power-saving mode. This universal design reduces device complexity by eliminating the need for multiple specialized converters
3Duration of action of moving object
If output power is interrupted first during power loss, then power down sequence is established, but auxiliary power interruption is delayed
Solution Approach 1:
The controller is configured to interrupt output power before interrupting auxiliary power during a power loss event. This preliminary action ensures that the auxiliary power continues to supply the load for a longer duration, providing a buffer period that allows for complete power down sequencing and reliable data logging before the auxiliary power is finally interrupted
