The invention discloses an energy-saving power supply system, belonging to a server power supply system. The system has the structure comprising power supply modules and a load unit, wherein each power supply module is used for converting AC commercial power into intermediate DC bus voltage, and the plurality of power supply modules are connected with each other in parallel to expand capacity forsupply power for the load unit; a DC bus between the power supply modules and the load unit is provided with a current detection unit which is used for sampling current output by the power supply modules and carrying out current-voltage conversion; the current detection unit is connected with a comparing control unit and provides the information obtained after current-voltage conversion for the comparing control unit; and the comparing control unit is connected with the power supply modules, receives the information provided by the current detection unit, outputs a control signal after comparing the information with the preset threshold value inside the comparing control unit, and controls on and off of the power supply modules. Compared with the prior art, the energy-saving power supply system has the characteristics of high efficiency energy conservation, high reliability, long service life, etc.
Description
technical field [0001] The invention relates to a server power supply system, in particular to an energy-saving power supply system. Background technique [0002] Now, from the perspective of pursuing high efficiency and high benefits, enterprises have put forward higher or even more stringent requirements for the performance of technological products, but the performance improvement of technological products is also accompanied by greater energy consumption. Today, when the country vigorously advocates "green energy saving", many manufacturers are making unremitting efforts to design qualified products with high efficiency and energy saving. High-end servers consume a lot of energy, and energy saving has become a key word in high-end server technologies. [0003] At present, server power supply efficiency can reach a relatively high level, with the highest efficiency at around 70% load, and can reach 92% efficiency, but the efficiency will be low under other load condition...
