Article studied asynchronous motor phased light load regulator of the principle of energy saving voltage regulator from the theory, impact of power efficiency of three key factors when the light load: Voltage, slip and power factor, proposed power-saving conditions. Running from the energy savings of view, in theory set up the ideas of the smallest energy consumption optimization target power factor...
System optimization techniques are widely used to improve energy efficiency as well as overall performance. Dynamic voltage scaling (DVS) is acknowledged to be successful in reducing processor energy consumption. Due to the increasing significance of the memory subsystem's energy consumption, dynamic cache reconfiguration (DCR) techniques are recently proposed at the aim of saving cache subsystem's...
In battery-powered embedded systems, dedicated circuitry is used to convert stored energy into a form that can be directly used by processors. These power regulation devices seek to mask non-ideal aspects of the battery and present an ideal, fixed-voltage power source to the processor. However, this comes at a high price in terms of form factor, component cost, and energy efficiency. We describe and...
Review of electric energy consumption in different countries shows that electric motors are among the most intensive electricity consumer equipments. Statistics indicate that about two third of industrial electricity in Iran is consumed through motor driven systems. Thus, it seems that these consumers would have considerable potential for energy conservation. In order to promote energy efficiency...
Dynamic voltage scaling is a technique that reduces the energy consumption in electronics systems. This paper deals with the design of the buck converter to meet dynamic voltage specifications and regulation under load current steps. A design methodology is proposed. Filter designs, number of interleaved phases, optimum switching frequency and control speed are key parameters that are taken into account...
