Design and Simulation Analysis of Bidirectional DC-DC Converter for Aircraft Battery Storage System

In this paper ultracapacitor-based battery system with a bidirectional double dynamic bridges DC to DC converter is investigated to fulfill the highest power requirements for aviation electrical loads like controllers and avionic infrastructure, as well as capture regenerating energy. Analysis of the DAB converter results in equations for the RMS and average currents of the device as well as the peak and RMS currents in the coupling inductor. The simulations have been used to test a DAB DC-DC conversion's functionality, demonstrating the precision of the study. Research information will be supplied to back up the research at the operational settings on 7kW, 3901/ 80 voltages, and 20 kHz, respectively.
