ملخص المقالة :

در این مقاله، یک مبدل غیر ایزوله بسیار افزاینده جدید با کلیدزنی نرم ارائه شده است. یک مدار کمکی با حداقل تعداد المان به مبدل پیشنهادی اضافه شده که شرایط کلیدزنی نرم را برای کلیه المان های نیمه هادی فراهم می نماید، لذا مشکل بازیابی معکوس دیودها را برطرف و تلفات کلیدزنی و هدایتی کلیدها را کاهش می دهد. همچنین، در مبدل پیشنهادی تنها از یک هسته مغناطیسی استفاده شده که موجب کاهش مقاومت مسی سیم پیچ ها می گردد، در نتیجه راندمان مبدل پیشنهادی در مقایسه با مبدل بوست متداول بهبود یافته است. همچنین برای پایداری ولتاژ خروجی مبدل در سطح دلخواه در لحظه های تغییر بار، از کنترل کننده انتگرالی تناسبی استفاده شده و نتایج شبیه سازی آن با نرم افزار متلب ارائه شده است. برای اثبات تحلیل های تئوری کلیدزنی نرم، یک نمونه آزمایشگاهی 250 واتی پیاده سازی گردیده و نتایج عملی آن ارائه شده است.
