Stray inductance in power electronics capacitors is due to the
magnetic field created by the currents in winding and connections. We
review different connection schemes that could be used in metallized
capacitors. For each of these connections, the stray inductance expression
depends of winding geometries. The proposed method to minimize this
inductance can be divided in two parts. The first part consists in
optimizing the winding geometry for a particular connection. The second is
the choice of a low-inductance connection for the previously determined
winding. The best results are obtained with large inner and outer radii and
through the use of inner annular conductors.
