Abstract

The invention provides a power system provided with stand-by power, comprising a stand-by power module and a first power supply module; wherein the stand-by power module only comprises an alternating current power supply input terminal, a stand-by power supply unit and a monitoring unit, the monitoring unit monitors whether the input alternating current power supply is cut off or not, so as to provide a control signal; the first power supply module is provided with an alternating current power supply input terminal, a controlled unit and a conversion unit, the controlled unit is connected with the output terminal of the stand-by power supply unit and is controlled by the control signal, so as to access the power supply provided by the stand-by power supply unit, and the conversion unit isused for carrying out corresponding conversion on the power supply provided by the stand-by power supply unit or the input alternating current power supply, so as to output a power supply required byload. As the controlled unit is arranged in the first power supply module, hot plug of the stand-by power module can be realized, and further the reliability of load power supply is improved.

Description

technical field [0001] The invention relates to a power supply system, in particular to a power supply system with backup power supply. Background technique [0002] In many key industries, such as banking, telecommunications, securities, etc., in order to ensure the safety and stability of online transactions and background databases, it is necessary to require the storage devices supporting these important businesses to work continuously and stably around the clock to achieve 24-hour uninterrupted operation. However, the prerequisite for the continuous and stable operation of the storage device is that its power supply has extremely high reliability. Generally speaking, in the key industries mentioned above, a single power supply is often unable to meet the harsh power supply requirements of the storage system. More generally, these storage devices use a dual power supply parallel power supply system. For example, in the Chinese patent document with the patent number 0224...
