چکیده

تولید پالس­های ولتاژ بالا با عرض فوق باریک و دوقطبی شده در حد چند نانو­ ثانیه و کمتر مورد توجه صنایع امروزی می­باشد. امروزه به دلیل اهمیت بالای ابعاد کوچک مولدهای پالسی، دوقطبی نمودن پالس­های تک‌قطبی جهت کاهش ابعاد مولد مورد نیاز، بسیار حائز اهمیت است. این مقاله در مورد نتایج طراحی و شبیه­سازی یک دوقطبی­کننده پالسی ولتاژ بالا با ولتاژ kV 300 و عرض پالس nS2 می­باشد. در این مولد پالس با استفاده از خطوط انتقال و موضوع انعکاس امواج در خطوط انتقال، ولتاژ تولیدشده به‌صورت متقارن دوقطبی درمی‌آید. ساختار واقعی مولد پالس بلوملین بر اساس ترکیب تو در توی چند خط انتقال است. ولتاژ خروجی این ترکیب تودرتو نسبت به ولتاژ خروجی مدل مداری آن کیفیت مناسبی ندارد. یکی از عوامل کیفیت نامناسب ولتاژ خروجی این مولد پالس، عناصر پراکندگی کلیدهای جرقه‌زن آن است. این مقاله با بررسی انواع مختلف الکترودهای کلیدهای جرقه­‌زن به بررسی تأثیر عنصر­های پراکندگی آنها بر شکل موج پالس دوقطبی شده می­پردازد.  نتایج شبیه­سازی برای نمایش کارایی طرح پیشنهادی ارائه می­‌شوند.

چکیده [English]

Nowadays, producing high voltage ultra-narrow bipolar pulse is considered in many applications. Considering the antenna or load, a bipolar pulse generator has many advantages compared to a unipolar pulse generator. Therefore, a high-power bipolar pulse generator has become a goal in the field of pulsed power. To achieve this goal, producing a bipolar pulse from a unipolar pulse is an important issue. Blumlein pulse generator is a widely used bipolar pulse generator with good performance. One of the issues in this pulse generator is the effect of spark gaps’ shape on the waveform of the output pulse. In this paper, a Blumlein bipolar pulse former has been considered, simulated and analyzed with different spark gap types. The effect of parasitic capacitance of these spark gaps in the transmission lines has been considered. The results of simulations can be used to design a bipolar pulse generator with acceptable output voltage waveform.
