Abstract

The embodiment of the invention provides power supply device and method. The method comprises the following steps of: controlling a first power supply to be opened for supplying power for a power receiving device and controlling a standby power supply of the first power supply to shut down; when the first power supply is in failure, leading a cell to be in a power supply state and controlling the standby power supply of the first power supply to start to supply power for the power receiving device. By using the power supply device and method, data in the power receiving device can not be lost due to power failure; and because the first power supply and the standby power supply of the first power supply do not simultaneously supply power for the power receiving device, the efficiency of the power supply is improved.

Description

technical field [0001] The invention relates to power supply technology, in particular to a power supply device and a power supply method. Background technique [0002] The operating efficiency of the power supply varies with the load of the power supply. Generally speaking, when the ratio of the load of the power supply (that is, the output power of the power supply) to the maximum power that the power supply can provide is 50%, the efficiency of the power supply is the highest. [0003] In the data storage device, the power consumption of the device changes continuously with the business volume, and the power consumption is high when the business volume is large. Generally, the ratio of the power required by the data storage device to the maximum power consumption of the data output device is about 50%. [0004] The power supply in the data storage device is usually 1+1 backup or 2+2 backup, which is to ensure that the data in the data storage device will not be lost due...
