چکیده

این مقاله یک اینورتر تک فاز تک مرحله ای بهبودیافته با چهار کلید را ارائه می‌کند. اینورتر پیشنهادی همانند اینورتر شبه منبع‌امپدانسی (qZSI) و اینورتر تقویت‌کننده شبه‌کلید‌زنی‌شده (qSBI)، دارای ویژگی‌های مهمی مانند جریان ورودی پیوسته، ولتاژ افزایند-کاهنده با تبدیل تک‌مرحله‌ای، ایمنی اتصال کوتاه و کارایی برای سیکل‌کاری‌های گوناگون است. در ادامه مقاله ابتدا نحوه عملکرد اینورتر پیشنهادی و نحوه کلید‌زنی آن بیان می‌شود و سپس تحلیل حالت دائمی آن ارائه می‌گردد. به منظور مشخص نمودن مزیتهای اینورتر پیشنهادی، مقایسه مبدل با ساختارهای مشابه ارائه می‌گردد. به منظور تأیید عملکرد صحیح و همچنین اثبات روابط ارائه شده، یک نمونه عملی از ساختار پیشنهادی در محیط آزمایشگاه پیاده سازی شده است. نتایج آزمایشگاهی اینورتر پیشنهادی در توان خروجی حدوداً 150 وات و در فرکانس کلیدزنی 10 کیلو هرتز استخراج شده است. نتایج و شکل‌‌موج های به دست آمده از تست آزمایشگاهی، عملکرد مبدل پیشنهادی، تحلیل حالت دائمی و کارایی آن را نشان می دهد.

چکیده [English]

This paper presents a modified single stage single phase inverter with four switches. The proposed inverter has important features such as continuous input current, voltage buck and boost with single stage conversion, short circuit safety and operation in various duty cycles same as qZSI and qSBI converters. In the rest of the paper, the suggested inverter operation mode and its switching method are described first and then, the steady state analysis is presented. To validate the merits of the proposed inverter, a comparison of the converter with similar topologies is provided. To verify the proper operation of the converter and also, to prove the presented theoretical calculations, a prototype of the introduced topology has been implemented in the laboratory. Test measurement results of the suggested inverter in 150 W with 10kHz frequency is derived. The obtained results and waveforms from test measurement present proposed inverter operation, steady state analysis and performance.
