English Abstract

Bus bars play a crucial role in connecting components and are widely utilized in high-power inverters. Efforts have been made in the past to reduce the stray inductance of bus bars. In the case of multilevel inverters, which involve more complex commutation loops than their two-level counterparts, the physical layout and parasitic parameters of bus bars are particularly important. Furthermore, for...
