درایوهای بدون جاروبک dc با توجه به بهره وری بالا، چگالی توان بالا، سهولت کنترل و نگهداری راحتتر، به طور گسترده ای در وسایل نقلیه الکتریکی و برنامه های کاربردی خودرو به عنوان موتور یا ژنراتور استفاده می شوند. ابتدا، این پایان نامه مروری بر جنبه های مختلف موتورهای bldc شامل ویژگی ها، مدل سازی، اینورترهای مورد استفاده و تحلیل روش های مختلف کنترلی و بیان نکات پیاده سازی درایو موتور bldc می پردازد....
gmelinoides fasciatus (stebbing, 1899) is a baikal endemic amphipod that has recently become widespread in eurasia. this species accidentally entered the cooling reservoir of the belovo power plant and became successfully naturalised there. this study describes the peculiarities of g. fasciatus distribution in reservoir sites with different thermal regimes and analyses the environmental factors...
The transmission of power using light instead electricity—the so called power-by-light (PBL)—has been around for some decades now. Despite this long history, it has only in recent years when PBL systems have experienced enormous effervescence situations where the direct use electrical energy to electronic equipment is either not possible or recommendable. are smarter solution monitoring and con...
We study the link between lobbying and industrial concentration.

sumption in active mode as a tradeoff to increased performance, but any power consumed when the system is idle is a complete waste and ideally should be avoided by turning the system off. A typical current system is so complex that parts of it will likely be inactive even during active periods, and they can be turned off to reduce power with no impact on performance. The introduction of finer-g...
