The Analysis of OCC and PI Control Method for Isolated Fly-Back Converter using PEM Fuel Cells

Öz

In this study, PI control and One Cycle Control techniques of Fly-Back Converter has been analyzed using PEM Fuel Cell. Fly-back converter is the most commonly used SMPS circuit for power applications where the output voltage needs to be isolated from the input main supply. Fly-back converters can both step-up and step-down the input voltage. These converters have been used various fields due to their properties of simply design and low cost especially low input-high output facilities. As Fly-back converters are running, they have to be preserve output voltage values according to not only changes of input and reference voltage also changes of loads values. Generally, there have been more solutions in order to provide constant output voltage. This paper aims at designing of a Fly-Back converter by using PI Control and One Cycle Control (OCC) techniques for constant voltage that is supplied by PEM Fuel Cell. Therefore, system behaviors and simulation results have been explained in this paper.

PEM Yakıt Hücreleri Kullanan İzole Fly-Back Dönüştürücünün Tek Döngü ve PI Denetim Metodu Analizi

Öz

Bu çalışmada, PEM yakıt pilleri kullanılarak Fly-Back Dönüştürücünün PI denetimi ve tek döngü denetimi teknikleri analiz edilmiştir. Fly-back dönüştürücü, yaygın bir şekilde çıkış geriliminin giriş geriliminden izole edilmesi gereken güç uygulamaları için anahtarlamalı güç kaynağı olarak kullanılmaktadır. Fly-back dönüştürücü, giriş gerilimini yükseltir veya düşürür. Fly-back dönüştürücüler düşük maliyet ve kolay tasarlanma özellikleri sayesinde özellikle düşük giriş yüksek çıkış elde etmek amacıyla birçok alanda kullanılmaktadır. Fly-back dönüştürücüler sadece giriş ve referans gerilim değerinin değişmesi değil aynı zamanda yük değerindeki değişikliklere rağmen çıkış gerilimini değerini sabitler ve korur. Genel itibariyle sabit çıkış gerilimi elde etmek amacıyla birçok çözüm bulunmaktadır. Bu makale, PEM yakıt hücreleri tarafından sağlanan sabit gerilim değerinin PI ve tek döngü denetim teknikleri kullanılarak tasarlanmasını amaçlamaktadır. Sonuç olarak, sistem davranışları ve benzetim sonuçları bu makalede açıklanmaktadır.
