Abstract

Bu makalede, basitleştirilmiş Bölünmüş Kaynaklı Evirici (BKE) için Model Öngörülü Kontrol (MÖK) yöntemi sunulmuştur. Basitleştirilmiş BKE, geleneksel BKE topolojilerinin giriş kısımda bulunan diyot ve anahtarlama elemanlarının çıkarılıp, H köprüsüne ilave bir anahtarın eklenmesiyle oluşmuştur. Geleneksel SSI topolojileriyle karşılaştırıldığında, basitleştirilmiş SSI daha az anahtarlama elemanı ve çift yönlü güç akış kabiliyeti gibi avantajlara sahiptir. Önerilen model öngörülü kontrol yöntemi, giriş ve çıkış akımlarını kontrol ederek eviricinin kararlı çalışmasını sağlayacak şekilde yapılandırılmıştır. Giriş ve çıkış bobin akımlarının referans değerleri, sırasıyla PI ve PR kontrolcüler ile üretilmiştir. PI kontrolcüye DA bara gerilim hatası uygulanırken, PR kontrolcüye AA taraf gerilim hatası uygulanmıştır. MÖK yöntemi, PI ve PR kontrolcü çıkışında elde edilen akım referansları ile tahmin edilen değer arasındaki hatayı minimize etmektedir. Böylece, dört kontrol değişkenine sahip basitleştirilmiş BKE eviricinin kontrolü sağlanmıştır. Önerilen kontrolcünün performansı MATLAB/Simulink platformunda gerçekleştirilen simülasyon çalışmalarıyla incelenmiştir. Farklı çalışma koşulları altında elde edilen kararlı durum ve dinamik yanıt sonuçları, önerilen yönteminin dört değişkenin eş zamanlı olarak başarılı bir şekilde kontrol edildiğini göstermektedir. Bununla birlikte çıkış gerilimi %2.34 gibi düşük bir toplam harmonik bozulmaya sahiptir.

Model Predictive Control Method for Simplified Split Source Inverter

Abstract

In this paper, a Model Predictive Control (MPC) method for a simplified Split Source Inverter (SSI) is presented. The simplified SSI is structured by eliminating the diode and switches on the input side and adding an additional switch to the H-bridge of conventional SSI topologies. Compared to conventional SSI topologies, the simplified SSI has fewer switches and bidirectional power flow capability advantages. The proposed model predictive control method is configured to ensure stable operation of the inverter by controlling the input and output currents. The reference values of the input and output inductor currents are generated by PI and PR controllers, respectively. While the DC bus voltage error is applied to the PI controller, the AC side voltage error is applied to the PR controller. The proposed MPC method minimizes the error between the current references obtained by the PI and PR controllers and their predicted values. Thus, controlling the simplified BKE inverter that has four control variables is achieved. The performance of the proposed controller is investigated by simulation studies performed on the MATLAB/Simulink platform. The steady-state and dynamic response results obtained under different operating conditions show that the proposed MPC method successfully controls the four variables simultaneously. In addition, the output voltage has a low total harmonic distortion of 2.34%.
