Beschreibung
Zusammenfassung:	This paper describes the principle of DC flux generation of a transformer in the boost mode of a current-type bi-directional isolated DC-DC converter and the effect of DC flux on circuit operation. Then, the circuit behavior in the case where the DC magnetic flux leading to magnetic saturation is generated is analyzed. Furthermore, this paper proposes a control method for suppressing DC flux in the boost mode of a current-fed bi-directional isolated DC-DC converter. Finally, the validity of theoretical analysis and the effectiveness of the proposed control method are verified through an experiment rated in 2.5kW.
