چکیده
This paper presents the simulation performance of Dual Active Bridge (DAB) DC-DC converter for high power density aerospace applications. The DAB converter topology has been chosen as it features high power density, high efficiency, bidirectional power flow capability, inherent soft switching, galvanic isolation and low number of passive components. Hence the converter is a candidate for high power density applications. For performance evaluation, input side of the converter is connected to the high voltage (HV) DC bus and output side of the converter is connected to the low voltage (LV) ultracapacitor. A 20kW DAB converter is modelled using SABER software. SABER simulation results verify that the performance of the DAB DC-DC converter is suitable for high power density applications such as aerospace energy storage systems. Key-Words: DC-DC converter, Dual active bridge topology, High power density, Ultracapacitor, Bidirectional operation, Galvanic isolation.
