Embodiment

[0021] A method for seamless switching between a server power adapter and a battery power supply, including detecting the input and output voltages of a power adapter switch, and when the input voltage is greater than the output voltage, the control switch is turned on; when the input voltage is lower than the output voltage, the power control chip controls the switch to be turned off ; Detect the input and output voltage of the battery-powered switch. When the input voltage is greater than the output voltage, the control switch is turned on; when the input voltage is lower than the output voltage, the power control chip controls the switch to be turned off. Both the power adapter and the battery power supply are connected to the load through a switch, and are used to provide power to the server.

Abstract

The embodiment of the invention provides a server power adapter and battery power supply seamless switching method, which comprises the following steps of detecting the input and output voltage of a power adapter switch; when the input voltage is greater than the output voltage, controlling the switch to be switched on; when the input voltage is smaller than the output voltage, controlling the switch to be switched off by a power supply control chip; detecting the input and output voltage of a battery power supply switch; when the input voltage is greater than the output voltage, controlling the switch to be switched on; when the input voltage is smaller than the output voltage, controlling the switch to be switched off by the power supply control chip. The power adapter and the battery power supply are both connected with a load through the switch, and are used for providing electric energy provide sth for the server. The method provided by the embodiment of the invention solves the problem of system power off or partial component power off caused by voltage drop possibly generated during the conventional switching from the power adapter to the battery power supply of the server.The product stability of the server is improved. The invention also provides a server power adapter and battery power supply seamless switching circuit.

Description

technical field [0001] The present invention relates to the field of servers. Background technique [0002] The current server design method for the power adapter and battery power supply is to use the power control chip to control the power adapter power path and the battery power path respectively, and use the system timing control chip to control the switch of the two power paths to achieve the purpose of system power switching. [0003] The problem with the existing design method of using the timing controller to control the switching between the power adapter and the battery power supply is that when the voltage of the power adapter drops out of the normal voltage range, the power control chip will send out an abnormal alarm signal, and the timing controller will receive the alarm signal Finally, it takes a period of processing before sending a control signal to the battery-powered control chip. [0004] At the same time, it takes a period of time for the battery-power...
