AI Technical Summary

Technical Problem

In multi-node servers, independent power supply modules lead to unbalanced loads and overload operation, affecting the scalability and adaptability of the power supply system. Furthermore, the failure of a single power supply module or AC interruption affects the stability and reliability of the server.

Method used

A multi-power module parallel power supply system is adopted, which realizes power resource sharing and redundancy backup through DC bus and power management module. The power management unit, DC-DC conversion unit and switching components in the power management module are used to coordinate the start-up and shutdown of power modules and load sharing.

Benefits of technology

It improves the scalability and adaptability of the power supply system, avoids overloading of a single module, extends the life of the power supply module, and maintains the stable operation of the computing unit in the event of a fault or AC interruption, thereby enhancing the reliability and fault tolerance of the multi-node server.
