| Abstract |
The increase of energy storage system power leads to open a technological pass which is to increase the voltage level of battery racks. Available 3.3 kV Silicon Carbide (SiC) semi-conductors implemented in an ANPC topology allows tuning a 3.6 kV DC bus.Thus, researches are shifting to medium voltage systems in which battery racks are connected in series with a middle point grounded. SiC modules implementation requires low inductive busbars to achieve high efficiency when rising in switching frequency necessary to shrink the output filter. In this paper, a methodology for reducing the parasitic inductor of the busbars (inf. 20 nH) is presented. |
