Zusammenfassung, Abstract
This paper presents a 4 kW GaN-based isolated bidirectional DC/DC converter suitable for on-board
auxiliary power supply systems, interconnecting the HV batteries with the LV on-board power supply
system. To enable the trend towards higher levels of electrification, a second LV level of 48 V is
introduced to supply the high-power consumers, relieving the 12 V grid on the one hand and/or
avoiding using additional costly isolated converters connected to the HV batteries on the other. The
built converter prototype aims to demonstrate higher efficiency, compactness and lower filter
requirements of the proposed circuit.
