Abstract

The invention discloses a main-standby power supply circuit and storage power supply equipment. The main-standby power supply circuit comprises a voltage stabilization buffer circuit, a PSU anti-backflow control circuit, a BBU anti-backflow control circuit and an overcurrent protection circuit. The voltage stabilization buffer circuit carries out voltage stabilization and voltage buffer processingon a power supply signal output by the PSU; when the PSU / BBU loses power, the PSU / BBU anti-backflow control circuit prevents a PSU / BBU power supply rear-end current from flowing back into the power supply line of the PSU / BBU; the over-current protection circuit detects a current signal input to an electric load and judges whether the current signal is greater than a preset over-current thresholdvalue or not, and if so, a load power supply line is cut off; and if not, the load power supply line is kept to be connected. Therefore, the main-standby power supply circuit is simple in overall design, and the voltage stabilization buffer circuit, the PSU anti-backflow control circuit, the BBU anti-backflow control circuit and the overcurrent protection circuit are all constructed by discrete devices so that cost is relatively low, and a fault loss is relatively small.

Description

technical field [0001] The invention relates to the field of power supply, in particular to a main and backup power supply circuit and storage power supply equipment. Background technique [0002] On storage servers, data reliability is particularly important. In order to ensure that the data on the storage server is not lost, most of the existing designs of the storage server adopt a dual power supply design of PSU (Power Supply Unit, power supply unit) and BBU (Battery Backup Unit, battery backup unit), and its working principle is as follows: When the main power PSU fails to supply power normally, the backup power BBU supplies power to the system to maintain the normal business data storage of the system and avoid data loss. However, most of the existing main and backup power supply lines are designed with integrated chips to ensure the safety and reliability of the main and backup power supply. Big loss. [0003] Therefore, how to provide a solution to the above techn...
