Abstract
An AC busbar for connecting at least three phases from a semiconductor switching unit to a load is provided. The AC busbar parallelly connects the at least three phases and provides current balancing. The AC busbar has a terminal-side conductor mechanically connectable to each AC terminal of the semiconductor switching unit and a load-side conductor positioned between the terminal-side conductor and the load. A distance between the terminal-side conductor and the load-side conductor is such that a difference in an inductance between a connection point for a respective AC terminal of each phase and a common point on a middle of the load-side conductor is less than a predetermined percentage with respect to an average of the respective inductances.
