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 اولCompact Wideband Differential Bandpass Filter Using a Marchand Balun
A novel compact wideband differential bandpass filter with wideband common mode suppression using a Marchand balun is presented in this paper. Open/shorted coupled lines and stubs are used to improve the selectivity for the differential mode and common mode suppression. The demonstrated filter with a compact size of 50mm × 30mm exhibits a fractional bandwidth of 53% centered at 3.0GHz and 13 dB...
متن کاملA Novel 180◦ Hybrid Based on the Modified Gysel Power Divider
A novel 180◦ hybrid is proposed, based on a modified Gysel power combiner, using phase shifter and ground bridge for the difference output. Also the Defected Microstrip Structure has been used to increase the hybrid’s phase matching. All steps of the design are simulated using HFSS 11 and the final design is validated by the fabrication. It has good results between 7 GHz to 10 GHz and can be us...
متن کاملA Novel High-Power Dual-Band Coupled-Line Gysel Power Divider with Impedance-Transforming Functions
A novel coupled-line structure is proposed to design dual-band and high-power Gysel power dividers with inherent impedance-transforming functions. Based on traditional even- and odd-mode technique, the analytical design methods in closed-form formula are obtained and the accurate electrical parameters analysis is presented. Due to the usage of coupled-line sections, more design-parameter freedo...
متن کاملFolded Marchand Balun Design and Validation Using Sonnet
The Marchand balun has larger bandwidth than other types of combiners and has been used extensively since its introduction. The Marchand balun has also been extensively used in planar systems in both broadside-coupled and edged-coupled configurations. This paper describes the design and development of two microstrip, folded, edge-coupled Marchand baluns for use as anti-phase power combiner. The...
