چکیده مقاله :
در این مقاله یک ساختار جدید از مبدل‌های DC-DC دوورودی و دوخروجی با بهره ولتاژ بالا مبتنی بر مبدل منبع امپدانسی T-Source ارائه شده است. کاربرد اصلی این مبدل برای اتصال به سیستم‌های انرژی‌های تجدیدپذیر می‌باشد. در این ساختار یک منبع ورودی پانل خورشیدی و دیگری یک باتری در نظر گرفته شده است. از مزیت‌های مبدل پیشنهادی می‌توان به بهره ولتاژ بالا، پیوسته‌بودن جریان ورودی، امکان جذب توان به صورت هم‌زمان و مستقل از باتری و پانل خورشیدی و بازدهی بالا اشاره کرد. مدهای عملکردی مبدل بررسی شده و معادلات حاکم بر آن در حالت پایدار به دست آمده است. شبیه‌سازی مبدل پیشنهادی انجام گردیده و یک نمونه آزمایشگاهی از مبدل ساخته شده است. مقایسه نتایج شبیه‌سازی و ساخت با تئوری پیش‌بینی شده برای کار سیستم، عملکرد مناسب مبدل پیشنهادی را تأیید می‌کند.
A new structure of multi-port DC-DC converter is proposed which is based on T-Source converter. It can be used for hybrid renewable energy applications. Two input ports includes a solar panel and battery. The main advantages of the converter are including; high voltage gain, continuous input current, independent mode operation of input ports, and high efficiency. Different switching modes are discussed in the relations for steady state operation of the converter are derived. A prototype of the converter is provided and several tests are performed which validates the simulations and theoretical predictions of the converter.
