چکیده

در این مقاله تحلیل ساختاری از مبدل dc- dc افزاینده تک‌ورودی-چندخروجی شامل یک سلف ارائه شده‌است. خروجی‌های این مبدل مستقل و منفصل از هم هستند و در کاربردهایی که نیاز به سطوح ولتاژ چندگانه (مجزا) و مستقل از هم به همراه شارش جریان یک‌سویه باشد، به کار می‌رود. لازم به ذکر است که حجم و اندازه مبدل موردنظر به‌دلیل دارابودن تنها یک سلف کاهش یافته‌است. از مزایای اصلی این ساختار می‌توان به عدم وجود ترانسفورماتور، امکان ساخت به‌صورت ماژولار و امکان کلیدزنی در فرکانس‌های بالا اشاره کرد. در این مقاله اصول عملکرد ساختار مذکور توضیح داده شده و تجزیه و تحلیل دقیق این ساختار انجام گرفته‌است. نتایج آزمایشگاهی مؤید صحت عمل‌کرد مبدل مستقیم- مستقیم کاهنده تک ورودی- چندخروجی ارائه شده‌است.

چکیده [English]

In this article the structural analysis of a single-input-multiple-output DC-DC boost converter including only one inductor is presented. The outputs of the converter are independent and detached from one another and, hence, the converter can be employed in such applications that require multiple and independent voltage levels (individual) with unidirectional current flow. Moreover, the size of the proposed converter is decreased because of having only one inductor. The main advantages of the proposed structure is the lack of transformer which leads to allowing for modular construction and the possibility for switching at high frequencies. In this paper, the operating principles of mentioned structure are explained and accurate analysis of this structure are conducted. Finally, the experimental results of this single-input-multiple-output DC-DC multiplier converter are presented in detail verifying the operation of this structure.
