Abstract

The invention discloses a power management method, which is applied to an IT system. The IT system comprises a first power supply group and a second power supply group. The method comprises the stepsof obtaining rated power of the first power supply group, rated power of the second power supply group and current power of the IT system; and if the current power of the IT system is smaller than orequal to a first percentage of the rated power of any power supply group in the two power supply groups, turning off a uniform current signal between the first power supply group and the second powersupply group, increasing an output voltage of the first power supply group and reducing an output voltage of the second power supply group. An embodiment of the invention furthermore provides a powermanagement apparatus. By adopting the method and the apparatus, the business stability can be ensured.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a power management method and device. Background technique [0002] A current information technology (Information technology, IT) system includes equipment such as a server, a memory, a switch, and a minicomputer. The system power supply of these devices is usually powered by 220V AC, 110V AC, -48V DC, or 240V high voltage DC. The internal power supply of each device is usually powered by a voltage of 12V or lower. The functional module that converts 220V to 12V is called the primary power supply module. In the primary power supply module, output power: input power = conversion efficiency. [0003] In an IT system, in order to achieve the purpose of backup, there are often multiple power sources. The main purpose of the backup is to maintain the normal operation of the system when one set of power supply input is powered off, and another set of power supplies can still pro...
