Abstract    Z-Source converter or impedance-source converter is a kind of power converters, which has the responsibility to convert the direct current to alternative current. This converter with respect to its circuit diagram acts as a buck-boost converter except it doesnít use from DC-DC converter bridge. Γ-source inverters are one of the conventional converters based on impedance-sources; which have been under considerations of professionals at power industries due to enhanced features. These features are contained boost of output voltage level, low number of active and passive elements and low requirement to achieve the high turn's ratio of coupling transformer. This paper dealt with the survey and modeling of gamma power source systems. In this regard, the first dynamic model of converter can be extracted by writing power balance equations. In addition, with the help of dynamic equations converter performance, analysis functionality will be available in various working conditions. Finally, the strategy of proper functioning will be provided for improving the performance of the converter.

چکیده    مبدل منبع Z یا مبدل منبع امپدانسی نوعی از مبدل های توان می باشد که وظیفه تبدیل جریان مستقیم به جریان متناوب را بر عهده دارند. این مبدل با توجه به شکل مداری که دارد، بعنوان مبدل افزاینده-کاهنده عمل می کند بدون اینکه از پل مبدل DC-DC استفاده کند. مبدل توان گاما یکی از مبدل های مبتنی بر منبع امپدانسی است که به علت ویژگی هایی نظیر تقویت سطح ولتاژ خروجی، تعداد عناصر اکتیو و پسیو کم و عدم نیاز به نسبت دور بالای ترانسفورماتور کوپلینگ مورد توجه متخصصین صنایع توان قرار گرفته است. در این مقاله به بررسی و مدلسازی سیستم های منبع توان گاما پرداخته می شود. در این راستا ابتدا مدل دینامیکی مبدل با نوشتم معادلات تعادلی توان استخراج می شود. با در دست داشتن معادلات دینامیکی امکان تجزیه و تحلیل عملکرد مبدل در شرایط کاری مختلف مهیا می شود. علاوه بر این استراتژی عملکردی مناسب برای بهبود عملکرد این مبدل ارائه خواهد شد.
