text: Utilisation of SiC semiconductors' fast switching speeds and high switching
frequencies as a consequent are often in discussion. But which switching frequency
is really optimal in terms of converter volume, losses and costs? Based on the
example of a buck converter, this question is investigated, and a tool for loss
calculation and design is described in this paper. A Pareto optimization of the
converter is performed where the switching frequency is one of several design
parameters. The buck converter can be realized by multiple rails interleaved,
and several switches can be placed in parallel. Considered converter modes are
continuous conduction mode, that allows hard-switching, ZVS, and incomplete ZVS
depending on the switching frequency. Based on Pareto optimizations, a design
is selected, and a laboratory sample of 5.5 kW for application in an EV battery
charger is built up. Efficiencies of 99.5 % are achieved with switching frequencies
of around 100 kHz.
