Tepe akım modu kontrollü izolesiz zeta dönüştürücünün küçük işaret analizi, benzetimi ve deneysel olarak gerçeklemesi

Bu çalışmada, matematiksel analizi gerçekleyen deneysel düzenekle birlikte bir izolesiz Zeta dönüştürücü sunulmaktadır. İlk olarak, tepe akım-mod kontrollü dönüştürücünün küçük işaret analizi gerçekleştirildi. Bunun için sürekli akım modunda PWM-anahtar modeli kullanıldı ve çıkış kondansatörünün eşdeğer seri direncini içeren çıkış gerilimi transfer fonksiyonu elde edildi. Kutuplar ve sıfırlar sembolik formda verildi ve sayısal bir örnek ile doğruluğu ispatlandı. Tepe akım-mod PWM-anahtar modelinin kullanılmasıyla elde edilen transfer fonksiyonunun paydası 5. mertebeden bir polinom olduğu için, kutuplar ve kalite faktörlerine ait çözümlerin takriben bulunması için yaklaşık kök analiz metodu kullanıldı. Önerilen Zeta dönüştürücünün Bode diyagramları için PSIM ortamında benzetim gerçekleştirildi ve benzetim sonuçları sembolik olarak elde edilen transfer fonksiyonun Bode diyagramları ile karşılaştırıldı. Daha sonra deneysel prototip oluşturuldu ve deney düzeneği hazırlandı. Gerçekleştirilen deneysel çalışmalar neticesinde sonuçların, anahtarlama frekansının yarı seviyesine kadar matematiksel sonuçlar ile uyum içerisinde oldukları gösterildi.
