analysis of power in the network society
اندیشمندان و صاحب نظران علوم اجتماعی بر این باورند که مرحله تازه ای در تاریخ جوامع بشری اغاز شده است. ویژگیهای این جامعه نو را می توان پدیده هایی از جمله اقتصاد اطلاعاتی جهانی ، هندسه متغیر شبکه ای، فرهنگ مجاز واقعی ، توسعه حیرت انگیز فناوری های دیجیتال، خدمات پیوسته و نیز فشردگی زمان و مکان برشمرد. از سوی دیگر قدرت به عنوان موضوع اصلی علم سیاست جایگاه مهمی در روابط انسانی دارد، قدرت و بازتولید...
15 صفحه اولPower Module with Series-connected MOSFETs in Flip-chip Configuration
Power module design is needed for high system performance and reliability, especially in terms of high efficiency and high power density. Low parasitic impedance and thermal management is desired for the lower power loss and device stress. For power module with high efficiency and improved breakdown voltage, this thesis proposes a novel series-connected power MOSFETs module. Three IRF7832 MOSFE...
متن کاملCurrent Sensing Power MOSFETs
SENSEFET PRODUCT Current sensing power MOSFETs provide a highly effective way of measuring load current in power conditioning circuits. Conceptually simple in nature, these devices split load current into power and sense components, and thereby allow signal level resistors to be used for sampling. Since this technique results in higher efficiency and lower costs than competing alternatives, und...
متن کاملPARALLELING POWER MOSFETs
Whenever devices are operated in parallel, due consideration should be given to the sharing between devices to ensure that the individual units are operated within their limits. Items that must be considered to successfully parallel MOSFETs are: gate circuitry, layout considerations, current unbalance, and temperature unbalance. This application note covers these topics and provides guidelines ...
متن کاملAN7244: Understanding Power MOSFETs
Power MOSFETs (Metal Oxide Semiconductor, Field Effect Transistors) differ from bipolar transistors in operating principles, specifications, and performance. The performance characteristics of MOSFETs are generally superior to those of bipolar transistors: significantly faster switching time, simpler drive circuitry, the absence of or reduction of the secondbreakdown failure mechanism, the abil...
