A Fast and Robust Model of Dual-Active Bridge Converters in Real-Time Simulation

Abstract

Real-time simulation is becoming an emerging and powerful tool for the development of power electronics conversion systems. One widely employed methods used in real-time (RT) simulations is the time average method. In this paper, a C-code average model is proposed for a two-level three-phase dual-active bridge dc-dc converter (2L-DAB3) to perform an efficient RT simulation. The calculation speed and accuracy as well as its stability with different integration methods are investigated and compared with state-of-the-art auto-generated models.
