This thesis is about the design of a Silicon Carbide power converter
that can be used in hybrid electric vehicle applications. It is
intended for a BAS (Belt driven Alternator and Starter) in a mild
hybrid car. Silicon Carbide is an innovative technology that seems
to have many advantages compared to the silicon that is commonly
used today. This design estimates on the different functions of a
BAS and the converter’s behavior in each case. The aim is to
estimate the converter’s losses over a standard driving cycle and
decide if it is possible then to use the combustion engine’s cooling
system to cool the semiconductors as well. If this is achievable then
we have to estimate a heat sink for that converter and see if there
is such heat sink on the market, or our demand is extreme.
