Abstract (2. Language): 
Self oscillating circuits do not require more complicated control circuit. So they can provide low cost power control with very simple control circuit. Because of these advantages the self oscillating circuit topology is widely used in some power electronics applications such as inverters and electronic ballasts. In this study, an application of self oscillating control technique was achieved on an induction heater driven by D-class inverter. Transistors used as power switches are triggered in order by the feedback signal which follows load current. For the developed self oscillating induction heating system, results obtained from simulations and experiments are compared and then presented.

Abstract (Original Language): 
Kendinden tetiklemeli devreler, fazla kontrol elemanı gerektirmediklerinden, basit kontrol devresi ve düşük maliyetle güç denetimi yapabilmektedirler. Bu üstünlükleri nedeniyle evirici ve elektronik balast gibi bazı güç elektroniği uygulamalarında kendinden tetikleme topolojisi kullanılmaktadır. Bu çalışmada, kendinden tetiklemeli denetim yönteminin bir uygulaması D-sınıfı eviricili bir indüksiyon ısıtıcı üzerinde gerçekleştirilmiştir. Güç anahtarları olarak kullanılan transistörlerin sırayla tetiklenmesi işlemi yük akımının değişimi izlenerek gerçekleştirilmiştir. Geliştirilen kendinden tetiklemeli denetim sisteminin simülasyon sonuçları ile deneysel sonuçları karşılaştırılmış ve sunulmuştur.
