Investigation of an Asymmetrical HighPower Medium-Voltage Dual-ActiveBridge
A dual-active bridge (DAB) consists of two converters connected back-to-back
through a transformer. This work focuses on the study of an asymmetrical dual-active
bridge in which one of the bridges produces multilevel voltage instead of two levels in
conventional DAB. The tasks included in this work are:
-
modeling and analysis of the converter topology,
-
simulation and model verification in Matlab/Simulink,
-
analysis of soft-switching boundaries and development of a suitable
modulation and control strategy,
-
evaluation of the converter performance with respect to conventional DAB.
Prior knowledge of power electronics and control systems is desirable but not
mandatory.
Good Luck!
