TCAD Investigation of Differently Doped DLC Passivation for Large-Area High-Power Diodes

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 ...

High-Power Pure Blue InGaN Laser Diodes

We fabricated high-power pure blue laser diodes (LDs) by using GaN-based material for full-color laser display. The operating output power, voltage and wall-plug efficiency of the LDs at forward current of 1.0 A were 1.17 W, 4.81 V and 24.3%, respectively. The estimated lifetime of the LDs was over 30,000 hours under continuous-wave operation. key words: InGaN, GaN, high-power laser, blue LD

New, large area, high power and efficient 172nm lamp

A highly efficient, continuous wave 172nm Xenon excimer lamp scalable in power, size and geometry is reported. Data from a prototype device based on multiple corona discharges, operating in dense Xenon gas, confirmed the concept. Results imply that large lamps with uniform VUV-light output exceeding 100mW/cm and wall plug electrical power to VUV light conversion efficiencies approaching 50% can...

Advancement of High Power Laser Diodes for Pumping 2-micron

The reliability and lifetime demanded by spacebased applications of 2-micron solid state lasers are beyond the capability of currently available laser diode arrays. This paper provides the status of an ongoing technology advancement effort toward long-lifetime high power laser diode arrays suitable for pumping Thulium and Holmium based solid state lasers.
