Solution Overview
Problem
The existing power supply apparatus requires a large number of power source conversion modules to achieve high reliability, leading to increased costs and space occupancy, especially for high-power devices, due to the need for N+N standby configurations.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If N+N standby is performed on power sources, then reliability is improved, but the number of power source conversion modules increases
Solution Approach 1:
The patent merges the functions of multiple power source conversion modules into a single integrated module. The power source conversion module is designed to accept multiple power sources (line-A and line-B) and automatically switch between them, eliminating the need for separate conversion modules for each power source while maintaining N+N standby capability.
Solution Approach 2:
The power source conversion module is designed with multi-functionality to handle both line-A and line-B power sources within a single device. The module can perform power conversion for either power source independently, making it a universal solution that replaces multiple specialized modules while maintaining the required reliability through automatic switching between power sources.
2Reliability
If the number of power source conversion modules is increased, then power supply reliability is improved, but space occupancy increases
Solution Approach 1:
The patent combines multiple power source conversion functions into a single integrated module, significantly reducing the space required. Instead of having separate conversion modules for line-A and line-B power sources, the invention integrates both conversion capabilities within one module, thereby reducing the total area occupied while maintaining the ability to provide redundant power supply.
3Reliability
If the number of power source conversion modules is increased, then power supply reliability is improved, but production costs increase
Solution Approach 1:
The patent merges multiple conversion functions into a single module, reducing the total number of components that need to be manufactured and assembled. This integration reduces production costs by eliminating redundant manufacturing processes while maintaining the reliability benefits of having multiple power source options.
Solution Approach 2:
The universal design of the power source conversion module allows a single type of module to serve multiple purposes (handling both line-A and line-B power sources), simplifying the manufacturing process and reducing costs associated with producing and managing multiple specialized module types.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution decreases the number of power source conversion modules needed while maintaining high reliability, reducing production costs and space requirements by allowing N+N standby with only N modules, and optionally adding more for enhanced redundancy.
Implementation Method 1
the conversion unit is configured to rectify an alternating current voltage output by the one alternating current power source, which is in the normal working state, in the channel closed by the detection and switching unit, and convert the alternating current voltage into a direct current voltage required by the load
