چکیده مقاله :
ساختارهای بسیار افزاینده عموماً برای ارتقاء سطح ولتاژ پایین تولید شده توسط منابع انرژی تجدید پذیر به کار گرفته می‌شوند. در این مقاله یک ساختار بسیار افزاینده مبتنی بر شبکه شبه امپدانس ارائه شده است، که دارای ساختاری ساده و در عین حال کاربردی متشکل از دو سلف و خازن می‌باشد. با توجه به ضریب وظیفه در محدوده ۵۰ درصد برای این مبدل مشکلات بازیابی معکوس دیودها و پایدارسازی مبدل برطرف می‌گردد. از طرفی زمین مشترک کلید قدرت و منبع ورودی باعث سادگی مدار کنترل می‌شود. با بهره گیری از تکنیک سلف کوپل شده و همچنین سلول چند برابر کننده ولتاژ، بهره ولتاژ مبدل به مقدار چشم‌گیری افزایش می یابد. علاوه بر آن در جهت محدود کردن تنش ولتاژ روی کلید، از خازن استک شده استفاده شده است. استفاده از ساختار پیشنهادی باعث افزایش بهره ولتاژ مبدل می‌گردد. همچنین ساختار ارائه شده سطح تنش ولتاژ روی نیمه هادی‌های مدار را کاهش می‌دهد که باعث کاهش هزینه و افزایش راندمان مدار می‌گردد. مبدل طراحی شده با ولتاژ ورودی 25 ولت و ولتاژ خروجی400 ولت و توان 100 وات در نرم افزار اسپایس شبیه سازی شده و نتایج در مقاله آمده است.
High step-up structures are commonly used to upgrade the low voltage levels generated by renewable energy sources. In this paper, a high step-up structure based on Quasi Z-Source network is presented, which has a simple yet functional structure consisting of two inductors and two capacitors. Due to the duty cycle of about 50% for this converter, the problems of reverse recovery of diodes and stability are solved. In addition, the common ground of the power switch and the input source simplifies the control circuit. Using the coupled inductor technique as well as the voltage multiplier cell, the converter voltage gain increases significantly. In addition, the stacked capacitor is used to limit the voltage stress on the switch. The use of the proposed structure increases the voltage gain of the converter. The proposed structure also reduces the level of voltage stress on the semiconductors of the circuit, which reduces the cost and increases the efficiency of the circuit. The converter designed with 25V/ 400V input/ output 100Wouput power is simulated in PSpice software and the results are presented.
