N2 - The demand for highly dynamic automotive electrical energy systems is increasing day by day. Battery electric vehicles contain high energy traction storages being capable of supplying low-voltage loads. This requires the development of a new electrical architecture that incorporates robust DCDC converters between the high-voltage battery and low-voltage components. In order to achieve high dynamics, a Phase-Shifted Full-Bridge (PSFB) converter is suitable. This paper introduces the scaling of a highly dynamic 400 V/12V PSFB to a lower 4SV/12V class while keeping the dynamic properties and responses. Verification between small-signal model and a switched simulation is performed. The prototyped scaled PSFB converter, while being subjected to high-dynamic current pulses, displays deviations with a maximum of 2 % in contrast to the 400 V/12V simulation model of the high-voltage PSFB converter.
