Engineering Contradiction Analysis
1Reliability
If an extra testing voltage source is used to test the over voltage protection function, then the testing can be performed, but the device complexity and cost increase
Solution Approach 1:
The patent combines the testing voltage source function with the power supply apparatus itself. The power supply apparatus outputs its original output voltage to serve as the testing voltage, eliminating the need for a separate testing voltage source. This merging of functions reduces device complexity and cost while maintaining the ability to test over voltage protection.
Solution Approach 2:
The power supply apparatus is designed to serve multiple functions: it acts as both the power source under test and the testing voltage source. By utilizing the original output voltage for testing purposes, the system achieves multi-functionality, reducing the need for additional dedicated testing equipment.
2Reliability
If the testing is completed with extra energy stored in the system, then the over voltage protection can be tested, but the energy release becomes slow after testing
Solution Approach 1:
The patent introduces a switch unit as an intermediary component that controls the energy release path. This switch unit enables rapid discharge of stored energy by providing a dedicated low-impedance path, solving the slow energy release problem while maintaining the ability to store energy during testing.
3Reliability
If an extra testing voltage source and complete energy release system are added, then the testing function is achieved, but the circuit structure becomes complicated and costly
Solution Approach 1:
The patent merges the testing voltage source function with the power supply apparatus's existing output capability. By using the original output voltage for testing purposes through the test contact, the system eliminates the need for separate voltage source equipment, reducing overall circuit complexity and cost.
Solution Approach 2:
The power supply apparatus performs self-testing by utilizing its own original output voltage as the testing voltage. The system tests its over voltage protection function using its inherent capabilities rather than requiring external testing equipment, achieving a self-service approach that simplifies the overall system.
