Stray inductance in power electronics capacitors is due to themagnetic field created by the currents in winding and connections. Wereview different connection schemes that could be used in metallizedcapacitors. For each of these connections, the stray inductance expressiondepends of winding geometries. The proposed method to minimize thisinductance can be divided in two parts. The first part consists in optimizing the winding geometry for a particular connection. The second isthe choice of a low-inductance connection for the previously determinedwinding. The best results are obtained with large inner and outer radii andthrough the use of inner annular conductors.
