Abstract in another language

Further automotive efficiency improvements require higher voltage levels than 14V for electric energy generation and distribution. As long as not all electric consumers can be adapted to the higher voltage level, DC/DC-converters link automotive power nets with different voltages. For low voltage converters without galvanic isolation mostly multiphase DC/DC-converters with coupled or uncoupled inductors are proposed due to their high power density. Multilevel architectures like the Flying Capacitor Multilevel DC/DC-Converter offer similar benefits and it will be shown that they need a smaller inductor size and provide better fault behaviour for short-on-failure switches. Efficiency is similar despite serial connected switches. This paper compares the two architectures regarding component count, control, size, fault tolerance and efficiency.
