Seria: Upravlenie, Vy£¿islitel£¿naa Tehnika i Informatika %D 2013 %I Astrakhan State Technical University %X For solution of the problem of increasing the efficiency of energy consumption of a group of personal computers, the method based on the system approach is presented. The interaction of both a separate switching power supply and the whole groups of power grids is studied. The results of modeling obtained in the Matlab + Simulink medium are given. The efficiency of the use of power correction factor in a single switching power supply is shown. The results of the studies are recommended to be used in organization of optimal interaction of computers with a power grid. %K : system approach %K energy conservation %K power correction factor %K power grid %K switching power supply %U http://astu.org/content/userimages/vestnik/file/inform_2013_1/11.pdf
