چکیده

در این مقاله یک مبدل ترکیبی بوست- سپیک با کلیدزنی نرم برای کاربردهایی که به بهره ولتاژ بالا نیاز دارند، ارائه شده است. یکی از ویژگی‌های اصلی در این مبدل روشن شدن سوئیچ اصلی تحت شرایط ZCS می‌باشد. این کار بدون بهره‌گیری از سوئیچ کمکی و مدارات اضافی انجام می‌شود. در این مبدل جهت افزایش بهره ولتاژ، خروجی مبدل سپیک با خروجی مبدل بوست سری شده که تشکیل یک مبدل ترکیبی را می‌دهند. علاوه بر این از یک سلف تزویج در مبدل بوست استفاده شده است که منجر به افزایش بیشتر بهره می‌گردد.برای ارزیابی عملکرد مبدل پیشنهادی نتایج شبیه سازی به همراه تحلیل وضعیت‌های عملکردی مبدل ارائه شده که نتایج به دست آمده صحت عملکرد مدار را نشان می‌دهد. همچنین با استفاده از نتایج آزمایشگاهیبر روی یک نمونه عملی ساخته شده صحت عملکرد مدار و تحلیل‌های مداری ارائه شده بررسی شده است

چکیده [English]

In this paper a compound boost- sepic converter with soft switching for high voltage application is proposed. One of the advantages of this converter is that, the main switch is turned on under the ZCS condition without need to any auxiliary switch so we have lower switching loss. In order to increase the voltage gain in this topology, a boost converter used in series with the output stage of sepic converter, therefore the output voltage of boost converter added to the output voltage of sepic converter and the voltage gain has been increased. Also a coupled inductor has been used in the boost converter topology which leads to a further increase in the voltage gain of the converter. In order to evaluate the operation of the proposed converter, simulation results and analysis of converter operational modes are presented. In addition, experimental results are presented for a typical boost-sepic converter. These results verify the proper operation of proposed converter.
