Loss Analysis of Dual Active Bridge DC-DC Converter for Aircraft Application
2020 International Symposium on Power Electronics, Electrical Drives, Automation and Motion (SPEEDAM)(2020)
摘要
In this paper a loss analysis of Dual Active Bridge DC-DC converter is performed. The circuit is conceived for DC Electrical Power Distribution System on aircraft, so leading to a 28V/270V system, whose operation in phase shift modulation is discussed. In particular, the paper proposes a comparison, in terms of power losses, among different wide band-gap commercial devices by means of thermal models suitable for accurate simulations in PLECS

environment. Numerical results highlight the impact of conduction and switching losses on system performance in terms of power density and safe operation.
