The flyback micro-inverters operating at discontinuous conduction mode are very attractive due to the operation in open loop and working without current sensor. In this paper, the working characteristics of a grid-connected photovoltaic micro-inverter based on flyback converter are investigated and design details are presented. “Perturbation and observation” method is used for maximum power point tracking. A micro-inverter prototype of 80 Wp is designed and produced. All the inverter functions, such as maximum power point tracking, islanding protection, serial communication, power control etc., are implemented by PIC24FJ64GA002 microcontroller. The measurements taken from protyped micro-inverter are compatible with design values. The highest efficiency of the converter was found as 80% and the loss mechanisms are discussed.
Kesikli iletim kipinde çalışan flyback mikro-eviriciler açık çevrim kontrol edilebilmeleri ve akım algılayıcısı olmadan çalışabilmeleri nedeniyle oldukça ilgi görmektedirler. Bu makalede flyback dönüştürücü tabanlı şebekeye bağlı bir fotovoltaik mikro-eviricinin çalışma karakteristikleri incelenmiş ve tasarım detayları verilmiştir. Maksimum güç noktası izleme için “değiştir ve gözle” algoritması kullanılmıştır. 80 Wp gücünde bir prototip mikro-eviricinin tasarımı yapılmış ve üretilmiştir. Maksimum güç noktası izleme, adalama koruması, seri haberleşme, güç kontrolü gibi eviricinin bütün kontrolleri PIC24FJ64GA002 mikrodenetleyicisi ile gerçekleştirilmiştir. Mikro-eviriciden alınan ölçümlerin tasarım değerleriyle uyumlu olduğu görülmüştür. Tasarlanan eviricinin maksimum verimi %80 olarak ölçülmüş ve oluşan kayıpların nedenleri irdelenmiştir.
