ملخص المقالة :

در این مقاله یک مبدل جدید DC-DC کاهنده رزنانسی از خانواده مبدلهای سوئیچ رزناتور (SwRC) ارائه شده است که شرایط سوئیچینگ نرم از نوع ZCS برای هر دو سوئیچ هم در گذار روشن شدن و هم در گذار خاموش شدن فراهم آمده است. از اینرو تلفات سوئیچینگ کاهش یافته و قابلیت افزایش فرکانس سوئیچینگ جهت ارتقاء چگالی توان مبدل فراهم گردیده است. تعداد المانهای بکار رفته در این مبدل پایین است و لذا صرفه اقتصادی خواهد داشت. همچنین دیود رزنانس در شرایط ZCS خاموش شده از اینرو پدیده بازیافت معکوس که خصوصا در دیودهای نوع سریع مشکل زا است مرتفع می گردد. به منظور فراهم کردن شرایط سوئیچینگ نرم برای تمام المانهای نیمه هادی، شبکه رزنانس LC مورد استفاده قرار گرفته است. نتایج شبیه سازی این مبدل با نرم افزار PsPice و نتایج ساخت آزمایشگاهی در این مقاله ارائه شده است. راندمان بدست آمده برای این مبدل %92.32 می باشد.
