چکیده

در این مقاله یک مبدل  DC/DCفوق افزاینده جدید با بهره ولتاژ بالا مبتنی بر افزایش ولتاژ بوسیله مبدل بوست دو مرحله­ای به همراه تکنیک­های خازن سوییچ شونده و سلف تزویج پیشنهاد شده است. در ساختار ارائه شده از دو سوئیچ استفاده شده که به صورت همزمان عمل می کنند. طرف ثانویه سلف تزویج با خازن سوییچ شونده به صورت یکپارچه درآمده و به علاوه انرژی نشتی سلف تزویج با تخلیه در سمت خروجی، بازیابی می­گردد. مبدل پیشنهادی با چند مبدل در مراجع دیگر از دیدگاه پارامترهای اصلی مقایسه شده است. با توجه به مقایسه­ها می­توان گفت که بهره ولتاژ مبدل پیشنهادی نسبت به چند ساختار پیشنهادی جدید بالاتر بوده و از طرفی استرس ولتاژ روی سوئیچ­ها و دیودهای آن پایین می­باشد و به سلف ورودی کوچکتری نیاز خواهد داشت. حالت­های عملکردی مبدل پیشنهادی به علاوه معادلات اصلی مبدل و طراحی المان­های ذخیره انرژی بطور کامل ارائه شده است. در آخر برای تایید معادلات نظری یک نمونه اولیه 150 واتی از مبدل پیشنهادی در نرم افزار متلب/سیمولینک شبیه­سازی گردیده و نمونه­ای از آن نیز ساخته شده است.

چکیده [English]

In this paper, a new ultrahigh step-up converter composed of two stages boost converter, a switched capacitor unit and coupled inductor is proposed. Secondary winding of the coupled inductor has been merged with the switched capacitor and leakage energy of the coupled inductor recycles through the output side. The structure contains two power switches which operate synchronously. The converter is compared from different points of view with the others presented in references. According to the results of the comparison, the converter boosts voltage with higher gain in comparison to the references. In addition, the converter requires smaller inductor in its input side and voltage stress on its semiconductors is low. This paper presents analysis of operation states, design of the inductors and main equations of the converter performance. To validate the analysis, results of simulation in SIMULINK MATLAB and experiments are utilized as the last section of the paper. The prototype is designed for 150W output power to boost input voltage with gain equal to 16.
