application of upfc based on svpwm for power quality improvement
در سالهای اخیر،اختلالات کیفیت توان مهمترین موضوع می باشد که محققان زیادی را برای پیدا کردن راه حلی برای حل آن علاقه مند ساخته است.امروزه کیفیت توان در سیستم قدرت برای مراکز صنعتی،تجاری وکاربردهای بیمارستانی مسئله مهمی می باشد.مشکل ولتاژمثل شرایط افت ولتاژواضافه جریان ناشی از اتصال کوتاه مدار یا وقوع خطا در سیستم بیشتر مورد توجه می باشد. برای مطالعه افت ولتاژ واضافه جریان،محققان زیادی کار کرده ...
15 صفحه اولThree-dimensional multiway power dividers based on transformation optics.
The two-dimensional (2D) or three-dimensional (3D) multiway power dividers based on transformation optical theory are proposed in this paper. It comprises of several nonisotropic mediums and one isotropic medium without any lumped and distributed elements. By using finite embedded coordinate transformations, the incident beam can be split and bent arbitrarily in order to achieve effective power...
متن کاملPower Aware Dividers in FPGA
This paper surveys different implementations of dividers on FPGA technology. A special attention is paid on ATP (area-time-power) trade-offs between restoring, non-restoring, and SRT dividers algorithms for different operand widths, remainder representations, and radices. Main results show that SRT radix-2 present the best ATP figure. In combinational implementation, an important power improvem...
متن کاملMiniaturization of Broadband Wilkinson Power Dividers
Received Jan 5, 2018 Revised Mar 3, 2018 Accepted Mar 20, 2018 This paper proposed three modified Wilkinson power dividers in order to achieve a size reduction and a wide bandwidth. The first structure presented the power divider using compact folded step impedance transmission lines rather than the uniform microstrip line design for operating center frequency of 3 GHz. The second structure sho...
متن کاملPower Comparison of Srt and Gst Dividers
Generally divider algorithms can be separated into two diierent kinds of algorithms, the Multiplicative Algorithms (MA) and the Iterative Digit Recurrence Algorithms (IDRA). The number of iterations of the MA and IDRA are proportional to log 2 (word?length) and the word-length, respectively. However every iteration of the MA consists of two multiplications and one addition, while the iteration ...
