Modelling of power electronic circuits using the bond graph method

Bu makalede, yeni bir anahtar tanımlı bond graf modelini kullanarak güç elektroniği devrelerinin modellenmesi sunulmuştur. Güç elektroniği elemanlarının yerine; parça-parça lineerlik yaklaşımı kullanılarak kaynaklar, lineer elemanlar ve anahtarlardan oluşan eşdeğer devreleri yer almıştır. Ayrıca durum ve çıkış denklemlerinin matematiksel modeli güç elektroniği elemanlarının ve devrelerinin bond graf modeli kullanılarak elde edilmiştir. Hazırlanan BOPEC isimli bilgisayar programına ilişkin sonuçlar verilmiştir.

Bond graf metodu kullanarak güç elektroniği devrelerinin modellenmesi

In this paper, the modelling of power electronic circuits using the bond graph method with a new switch definition is presented. Power electronic components are replaced with their equivalents composed of the sources, linear components and switches by using piecewise-linear approximation. In addition, a mathematical model of state and output equations is obtained by using the bond graph model of power electronic components and circuits. The results produced by the prepared general purpose computer programme BOPEC are given.
