Abstract
This paper proposes a time-domain modelling approach for a multi-winding transformer-based multilevel DC/DC converter. Within previous research, multi-winding transformers have been modeled using cantilever models. These models, while simple, have no direct intuitive interpretation. Furthermore, they do not include currents circulating within each individual module and external load currents affecting only some of the modules at the same time. In this paper, a DC/DC converter model that includes the transformer as N-port network with magnetization and stray inductance and conduction losses is proposed. The model is verified using simulations showing both accurate predictions of both, circulating currents within each module and load currents affecting multiple modules.
