Parallel Power Supply Built-in Test Switch Self-Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional parallel power supplies require insertion into a system or fixture for power detection, which can risk damaging data or the system and necessitate frequent adjustments, and often lack suitable test fixtures due to differing pin configurations.
Innovation Solution
Incorporating a built-in test switch and control unit within the parallel power supply to generate detection signals, enabling internal power detection without system or fixture insertion, using a display or audio unit to indicate operational status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the parallel power supply is inserted into a system or fixture for power detection, then the operation status can be detected, but the risk of damaging data or the system increases
Solution Approach 1:
The power supply performs self-detection of its own operation status through a built-in test switch and control unit, eliminating the need for external system or fixture insertion. The self-detection mechanism allows the power supply to test its own functionality independently, thereby achieving power detection capability without exposing the system or data to damage risks.
2Productivity
If the parallel power supply is frequently inserted and pulled out of the system for detection, then the operation status can be checked, but the system may be damaged
Solution Approach 1:
The power supply independently performs self-detection through its built-in test switch without requiring removal from or insertion into the system. This eliminates frequent physical connections and disconnections, thereby maintaining high detection efficiency while preventing system damage that would result from repeated插拔 operations.
3Adaptability or versatility
If different types of test fixtures are used for different pin configurations, then various power supplies can be tested, but the device complexity increases
Solution Approach 1:
Each power supply is equipped with a built-in test switch and self-detection capability, allowing it to independently test its own operation status. This eliminates the need for multiple external test fixtures with different pin configurations, thereby maintaining versatility in testing different power supply types while significantly reducing device complexity.
4Measurement precision
If the parallel power supply is inserted into a fixture for yield management, then quality detection can be performed, but the process time increases
Solution Approach 1:
The power supply performs self-detection through its built-in test switch without requiring external fixture insertion. The control unit automatically enables the detection mechanism upon receiving a detection signal, allowing quality detection to be performed quickly and accurately without the time-consuming process of physical insertion and removal from fixtures.
