Ac busbar for current sharing between parallelly connected semiconductor switching pairs

An AC busbar configured to connect at least three phases from a semiconductor switching unit to a load, each phase having an AC terminal, wherein the at least three phases are connected in parallel by the AC busbar, the AC busbar comprising:

• a terminal-side conductor mechanically connectable to each AC terminal of the semiconductor switching unit;
• a load-side conductor positioned between the terminal-side conductor and the load, the load-side conductor being parallel to the terminal-side conductor;
• two connecting conductors connecting the terminal-side conductor and the load-side conductor;
• and
• a conductor orthogonally projecting from the load-side conductor, the orthogonally projecting conductor configured to be connected with the load, the orthogonally projecting conductor is centered on the load-side conductor, wherein 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.
