ملخص المقالة :
در اين مقاله يک مبدل غير ايزوله SEPIC جديد که براي کاربردهاي فتوولتائيک مناسب ميباشد، معرفي و آناليز شده است. به علت پايينبودن ولتاژ خروجی سيستمهای فتوولتائيک و نياز به ولتاژ خروجی بالا در بسياری از کاربردها از جمله کاربردهای متصل به شبکه، اين مبدل با بهره ولتاژ بالا طراحی شده است. اين مبدل مزايايي از قبيل ولتاژ خروجي بالا با همان استرس ولتاژ مبدل SEPIC عادي و بازده بالا را دارا ميباشد. در اين مبدل کليد تحت شرايط ZVS در حالت روشنشدن و ZCS در حالت خاموششدن عمل ميکند، به همين دليل تلفات سوئيچينگ کاهش مييابد.
