Battery integration with more electric aircraft DC distribution network using phase shifted high power bidirectional DC-DC converter

Competition in the aircraft industry market and global warming has driven the industry to think along economic and environmental lines. This has resulted in the emergence of More Electric Aircraft (MEA). A new DC standards for power distribution has been obtained with 270 V DC on board of MEA. Because of its high electric power demand MEA requires high energy density batteries and DC-DC converter system. The DC-DC converter functions as a charger for batteries. The features like high performance and galvanic isolation make the phase shifted bidirectional DC-DC converter (also known as Dual Active Bridge) a strong candidates amongst the available DC-DC converters. In this paper, authors have integrated a high energy density Li-ion battery system with power distribution DC bus using phase shifted high power bidirectional (PSHPB) DC-DC converter and proposed a simple dynamic duty cycle control (DDCC) algorithm for its operation under dynamic conditions. The full system is verified under different dynamic conditions with variations in output current (load) and input voltage (line). The modeling has been done in MATLAB® Simulink environment, and simulation results are presented and discussed in the paper.
