چکیده مقاله :

در این مقاله یک مبدل دوطرفه جدید ایزوله ارایه شده بطوری که با استفاده از یک اسنابر جدید بدون سوییچ اضافی، کلیدزنی نرم برای هر دو سوییچ اصلی فراهم شده و انرژی مدار اسنابر به خروجی منتقل می‌گردد. تعداد المان مبدل پیشنهادی پایین است و کنترل آن به علت اینکه در هر طرف تنها یک سوییچ عمل می‌کند و سوییچ دیگر فرمان نمی‌گیرد، بسیار ساده است. یکی از ویژگی‌های آن عدم استفاده از سلف‌های جداگانه در مدار اسنابر و استفاده از سیم پیچ سوم برای مدار اسنابر می‌باشد. عملکرد مبدل پیشنهادی به طور کامل تحلیل گردیده و در نرم افزار PSPICE شبیه‌سازی شده است که نتایج آن تحلیل تئوریک مبدل را تایید می‌کند. از طرفی یک نمونه 80 وات از آن ساخته شده است که نتایج عملی آن ارایه شده است.

چکیده انگلیسی:

In this paper, a new isolated bidirectional converter is presented so that by using a new snubber without any additional switch, soft switching is provided for both main switches and the energy of the snubber circuit is transferred to the output. The number of proposed converter elements is low and its control is very simple because only one switc5h operates on each side and the other switch does not take command signal. One of its features is not using separate inductors in the snubber circuit and using the third coil for the snubber circuit. The performance of the proposed converter has been fully analyzed and simulated in PSPICE software, the results of which confirm the theoretical analysis of the converter. On the other hand, an 80W prototype has been made from it, and its practical results have been presented.
