Abstract

In this study, a new interleaved-based bidirectional isolated multi-port DC-DC converter with an effective control structure for photovoltaic (PV) panel powered and battery buffered systems is proposed. The proposed converter is designed to perform the optimum power flow between generation/storage/load units. In the designed system, the power transfer between the PV panel and the battery is provided by the control of the left leg switches of the interleaved DC-DC converter, while the power transfer between the energy generation/storage units and the loads is provided by the control of the right leg switches of the relevant circuit. With two half-bridge circuits on the secondary side of the high-frequency transformer (HFT), which provides load side isolation, two ports with different voltage levels and which can be controlled independently of each other are formed. In the proposed converter, the power flow between the ports is handled by a multi-loop control scheme that is able to smoothly switch between control loops. Simulation studies have been conducted in the PSIM program to verify the viability and effectiveness of the proposed multiport converter. The performance of the proposed converter is analyzed under dynamic conditions such as different radiation and loading conditions. The power flow capabilities and high efficiency values (>98%) validates the viability and effectiveness of the proposed converter

Fotovoltaik Panel ve Batarya Entegre Sistemler için Yeni Bir Interleaved Tabanlı Çok Portlu İzole DA-DA Dönüştürücü Analizi

Abstract

Bu çalışmada, fotovoltaik (FV) panel ile çalışan ve batarya destekli sistemler için etkin bir kontrol yapısına sahip interleaved tabanlı çift yönlü çok portlu izole yeni bir DA-DA dönüştürücü önerilmektedir. Önerilen dönüştürücü, üretim/depolama/yük birimleri arasındaki optimum güç akışını denetlemek için tasarlanmıştır. Tasarlanan sistemde, FV panel ve batarya arası güç transferi interleaved DA-DA dönüştürücünün sol kol anahtarlarının kontrolü ile sağlanırken, enerji üretim/depolama birimleri ile yükler arası güç transferi ilgili devrenin sağ kol anahtarlarının kontrolü ile sağlanmaktadır. Yük tarafının izolasyonunu sağlayan yüksek frekans transformatörünün (YFT) ikincil tarafında bulunan iki yarım köprü devresi ile birbirinden bağımsız kontrol edilebilen ve farklı gerilim seviyelerine sahip iki port oluşturulmaktadır. Önerilen dönüştürücüde portlar arasındaki güç akışı kontrol döngüleri arasında yumuşak geçiş yapabilen çok döngülü bir kontrol şeması tarafından gerçekleştirilmektedir. Önerilen çok portlu dönüştürücünün uygulanabilirliğini ve etkinliğini doğrulamak için, PSIM programında simülasyon çalışmaları gerçekleştirilmiştir. Önerilen dönüştürücünün performansı farklı ışınım ve yüklenme durumları gibi dinamik koşullar altında analiz edilmiştir. Güç akış yetenekleri ve yüksek verimlilik değerleri (>%98) önerilen dönüştürücünün uygulanabilirliğini ve etkinliğini doğrulamaktadır
