AI Technical Summary

Technical Problem

In the CRPS power architecture, existing general-purpose redundant power supplies lack independent input source selection signals and cannot perform power switching.

Method used

By multiplexing the bits in the power address bits of the general redundant power supply as control signals to trigger input source switching, and using internal combinational logic circuits to analyze the high and low level states of the bits, automatic selection and switching of the input source can be achieved.

Benefits of technology

Dual-input switching of a general-purpose redundant power supply is achieved without adding extra pins, improving the system's flexibility and reliability under pin-restricted conditions.

Abstract

This application provides an input source switching method, apparatus, universal redundant power supply, and server. The method includes: acquiring a power switching signal, wherein the power switching signal represents the level state of a target signal in the universal redundant power supply; the target signal corresponds to a bit in the power address bits that is multiplexed to trigger an input source switching action, and the power address bits are the address bits of an address setting pin in the universal redundant power supply; the level state is used to instruct the universal redundant power supply to select an input source; and switching the input source of the universal redundant power supply according to the power switching signal. This method is used to implement input source switching of a universal redundant power supply.
