Abstract in another language

In this paper, a bidirectional, non-isolated dc–dc converter with several interleaved phases of multilevel modules for automotive power systems is presented. Instead of using a 2-level stage with short-circuit protection elements, a 3-level module in a multiphase structure is proposed to achieve improved fault-tolerance. The dimensioning of the required flying capacitor for multilevel dc–dc converters is described. Further benefits like ripple reduction, automatic fault current limitation and enhanced efficiency are achieved. Moreover, the control strategy for normal operation including the stability of the flying capacitor voltage as well as reconfiguration after failure for degraded operation are explained.
