Embodiment Construction
[0033] The core of the present invention is to provide a power supply circuit and server for the device to be refreshed. When the system power supply is normal, the AC power supply of the system provides the power required for refreshing the device to be refreshed; when the system power supply is abnormal, switch from the backup power supply to The device to be refreshed provides the power required for refresh to avoid the risk of refresh failure when the system suddenly has an abnormal power supply; and when the device to be refreshed is refreshed, the backup power supply is always ready to seamlessly switch to the Standby power supply.
[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described e...

The invention discloses a power supply circuit of to-be-refreshed equipment and a server. The conversion circuit converts the alternating current power supply into a first power supply for supplying power to the equipment to be refreshed when system power supply is normal; when the to-be-refreshed equipment is refreshed, the alternative circuit outputs a second power supply for supplying power tothe to-be-refreshed equipment by utilizing the electric energy of the standby power supply; the switching circuit judges whether system power supply is normal or not when the to-be-refreshed equipmentis refreshed; if yes, a conversion circuit is switched to supply power to the to-be-refreshed equipment; and if not, the alternative circuit is switched to supply power to the to-be-refreshed device.Visibly, when system power supply is normal, the alternating-current power supply supplies electric energy required by equipment refreshing; when the system power supply is abnormal, the standby power supply provides electric energy required by equipment refreshing, so that the risk of refreshing failure caused by sudden abnormal power supply of the system is avoided; and when the to-be-refreshedequipment is refreshed, the standby power supply is in a time preparation state so as to seamlessly switch to the standby power supply to supply power when the system suddenly supplies power abnormally.
Description
technical field [0001] The invention relates to the field of servers, in particular to a power supply circuit of a device to be refreshed and a server. Background technique [0002] In the field of servers, BMC (Baseboard Management Controller, Baseboard Management Controller) is a monitoring and management device, which is responsible for monitoring hardware devices (such as fans, temperature sensors, voltage sensors, etc.) around the server. At present, the BMC firmware can be refreshed in various ways such as the web, offline programming tools, and refresh tools in the server system to increase the functions of the BMC. Among the various refresh methods, on-site users use more refresh methods to refresh through the web and refresh tools in the server system, but these two refresh methods all have the risk of refresh failure when the server is suddenly powered off. [0003] Therefore, how to provide a solution to the above technical problems is a problem that those skille...
