Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If optical fiber interface is used for communication between centralized controller and unit controller, then communication reliability is improved, but hot swap capability is lost and installation complexity increases
Solution Approach 1:
The patent introduces an electrical interface as an intermediary communication medium between the centralized controller and unit controller, replacing the optical fiber interface. This electrical interface enables hot swap capability while maintaining communication reliability through standardized electrical connections that support plug-and-play operations.
2Stability of the object's composition
If optical fiber installation is required for each power unit, then communication stability is improved, but on-site installation and maintenance reliability deteriorates
Solution Approach 1:
The patent replaces the mechanical optical fiber installation system with an electrical interface system. The electrical interface uses standardized connectors that eliminate the need for complex optical fiber routing and termination, significantly improving on-site installation and maintenance reliability while maintaining communication stability.
3Measurement precision
If optical fiber communication is used between controllers, then control precision is improved, but system complexity increases
Solution Approach 1:
The patent extracts the communication function from the optical fiber interface and implements it through a simplified electrical interface. This extraction removes the complex optical fiber infrastructure while preserving the essential control precision requirements through standardized electrical signaling protocols.

AI summary
A power system, a data center, and a charging device are provided, and relate to the field of electronic power. The power system includes a centralized controller (10) and three power modules (11). Each phase of an alternating current power supply is connected to one power module (11), and an input end of each power module (11) is connected to one phase of the alternating current power supply. Each power module (11) includes a low voltage controller (30) and at least two power units (20). Each power unit (20) includes a unit controller (201). The centralized controller (10) is connected to each low voltage controller (30) by using a bus. The centralized controller (10) sends a control signal to each unit controller (201) by using each low voltage controller (30), to control the unit controller (201) and/or a power conversion circuit (210). The power system can implement hot swap of the power module (11) and improve on-site operation reliability.
