Abstract
Bu makalede, değişken bir çıkış gerilimi ve kademeli olarak değişen bir çıkış frekansı elde etmek için tek fazlı matris dönüştürücü ile birlikte Z-kaynak ağı kullanılan bir alternatif akım-alternatif akım (AA-AA) dönüştürücü yapısı incelenmiştir. Bu dönüştürücü yapısında, çıkış gerilimi ve frekansı hem düşürülebilmekte hem de yükseltilebilmektedir. Matris dönüştürücü, doğrudan AA-AA dönüşüm yaparken anahtarlama stratejisi ile çıkış frekansını kademeli olarak değiştirme imkânı sağlamaktadır. Ayrıca, doğrudan AA-AA dönüştürme özelliği sayesinde, geleneksel dönüştürücülerde kullanılan büyük bir DA bağlantı kondansatörüne olan ihtiyacı ortadan kaldırmıştır. Böylece sistem hem daha az maliyetli hem de daha az karmaşık bir yapıya sahip olmaktadır. Bu çalışmada, çeşitli uygulamalarda farklı hız değerlerini elde etmek için kullanılan tek fazlı asenkron motoru sürmek için tek fazlı Z-kaynaklı matris dönüştürücü kullanılmıştır. Bu yapı, asenkron motorun başlatılmasında veya kademeli bir hıza ihtiyaç duyan asenkron motorun hız kontrolünde kullanılabilmektedir. Tek fazlı Z-kaynaklı matris dönüştürücü MATLAB/Simulink ortamında modellenerek simülasyonu yapılmış ve farklı frekans değerleri için simülasyon sonuçları hem direnç-bobin (RL) yükü için hem de tek fazlı asenkron motor için sunulmuştur. Dönüştürücü akım ve geriliminin harmonik spektrumu da incelenerek, harmonik bozulma değerleri farklı frekanslar için verilmiştir.

Abstract
In this article, an alternating current-alternating current (AC-AC) converter structure using a single-phase matrix converter together with a Z-source network is examined to obtain a variable output voltage and a gradually varying output frequency. In this converter structure, the output voltage and frequency can be both reduced and increased. The matrix converter provides the opportunity to gradually change the output frequency with the switching strategy when performing direct AC-AC conversion. With this direct AC-to-AC conversion feature, it has eliminated the need for a large DC link capacitor used in conventional converters. Thus, the system is less costly and has a more compact structure. In this study, a single-phase Z-source matrix converter is used to drive a single-phase asynchronous motor, which is used to obtain different speed values in various applications. With this structure, it can be used to start an asynchronous motor or to control the speed of an asynchronous motor that needs a gradual speed. Single-phase Z-source matrix converter is modeled and simulated in MATLAB/Simulink environment and simulation results are given for different frequency values for both resistance-induktance (RL) load and single phase induction motor.
