اینورتر منبع امپدانسی فعال جدید با تنش ولتاژ کاهش یافته در دو سرکلیدها

ملخص المقالة :

در این مقاله، یک اینورتر منبع امپدانسی فعال جدید با تنش ولتاژ پایین‌ در دو سر المان‌ها و بهره ولتاژ مناسب پیشنهاد می‌شود. این ویژگی اینورتر پیشنهادی باعث کاهش سایز، حجم و قیمت تمام شده ساختار می‌گردد. اینورتر پیشنهاد شده از دو بخش منبع امپدانسی در سمت ورودی و پل H در سمت خروجی تشکیل شده که ولتاژ خروجی سه سطحی را ایجاد می‌کند. تجزیه و تحلیل حالت‌های کاری و روش کنترلی اعمال شده برای تولید پالس های گیت کلیدها ارائه‌ شده و بهره ولتاژ ساختار پیشنهادی محاسبه می شود. علاوه بر این، اجزای فعال و غیرفعال (اکتیو و پسیو) ساختار پیشنهادی طراحی می‌گردد. در ادامه، تحلیل مقایسه‌ای از نقطه‌نظرهای بهره ولتاژ، تنش ولتاژ دو سر کلیدها، دیودها و همچنین مجموع ولتاژ خازن‌ها به همراه نمودار مقایسه‌ای مربوط به تعداد المان‌ها، ما بین ساختار پیشنهادی و چند ساختار امپدانسی مرسوم، فراهم گردیده است. در آخر، ساختار پیشنهادی در محیط PSCAD طراحی شده و نتایج آن به طور کامل تحلیل می‌شود که این نتایج عملکرد مناسب ساختار پیشنهادی و صحت معادلات به ‌دست‌ آمده را نشان می‌دهد
