AYRIŞTIRMALI YÜKSELTİCİ TİP GÜÇ DÖNÜŞTÜRÜCÜSÜ İÇİN GERÇEK ZAMANLI MİKRODENETLEYİCİLİ KONTROLCÜ TASARIMI

Öz

Devre ve kullanılan elemanların boyutlarını küçültmek, çıkış gerilimi dalgalılık ve darbe genlik modülasyonu doluluk oranını azaltmak için literatürde paralel yapıdaki yükseltici tip güç dönüştürücüsü önerilmiştir. Bu yapının yüklü ve yüksüz durumda kararlı çıkış sağlayabilmesi için çeşitli kontrol metotları uygulanmış ve performansları deneysel ortamda karşılaştırılmıştır. Tasarlanan sistem, integral, oransal-integral, bulanık mantık kontrol metotlarının uygulandığı gerçek zamanlı mikro denetleyici temelli bir geri besleme yapısı içermektedir. Elde edilen sonuçlara göre bulanık mantık denetleyicili sistemin tepki süresi diğer yöntemlere göre daha düşük olduğundan dolayı güç verilen sistem için daha kararlı bir güç kaynağı olmaktadır.

DESIGN OF A REAL-TIME MICROCONTROLLER FOR INTERLEAVED BOOST CONVERTER

Öz

Interleaved boost converters proposed in the literature for reduce the size of the circuit and the amount of components, and to decrease the output voltage ripple and pulse width modulation duty cycle. In order to obtain a stable voltage at the output of interleaved boost converters, various control methods have been applied and the performances have been compared in the experimental environment. The proposed system consists of a real-time microcontroller-based feedback structure in which integral, proportional-integral, fuzzy logic control methods are applied. According to the results, the response time of the fuzzy logic controller system is lower than other control methods, so it becomes a more stable power source for the energized system.
