چکیده

در این مقاله یک مبدل کلیدزنی نرم غیره­ایزوله بسیار افزاینده ولتاژ ارائه شده است. مبدل پیشنهادی ترکیبی از یک مبدل بوست و دو سلول ضرب­کننده ولتاژ است. در این مبدل برای تحقق افزایش بهره ولتاژ از یک سلف کوپل شده استفاده شده است. این مبدل در مقایسه با مبدل­های مشابه دارای بهره ولتاژ بالاتری است. با استفاده از یک مدار کلمپ اکتیو شرایط کلیدزنی نرم در ولتاژ صفر برای کلید­های مبدل به­وجود آمده است. همچنین تنش ولتاژ بر روی کلید­ها پایین است. کاهش تنش ولتاژ بر روی کلید­های مبدل باعث کاهش مقاومت هدایتی کلیدها و بنابراین باعث کاهش تلفات هدایتی می­شود. در این مقاله عملکرد اولیه مبدل به­طور کامل تشریح شده و نتایج شبیه­سازی و یک نمونه آزمایشگاهی ساخته شده برای ولتاژ ورودی 20 ولت و خروجی 400 ولت در توان 200 وات به­طور کامل ارائه شده است.

چکیده [English]

In this paper, a non-isolated high step-up soft-switching converter is proposed. The proposed converter is a boost converter combined with two voltage multiplier cells for boosting output voltage. Also, extend voltage gain of the proposed converter is achieved by using a coupled-inductor. Compare with other similar high step-up topologies with the same number of components, the proposed converter has a higher voltage gain and higher efficiency. An active clamp circuit is used so, the zero-voltage switching (ZVS) is achieved. Also, in the proposed converter, the voltage stresses on the switches are low. As the voltage stress decreases on the switch, Ron of the MOSFET is deceased and as a result conduction loss of the switch is decreased. So, the efficiency of this converter increased. In this paper, operational principle of the converter is described and the analytical, simulated results and prototype converters are validated using a 20V input and 400V output converter at 200W load.
