While steady-state analysis of aluminum electrolytic capacitors is straightforward, predicting transient electrical and thermal response is much more involved. In this presentation the modeling of transient electrical, thermal and lifetime behavior of aluminum electrolytic capacitors is discussed, focusing on large (> 0.1 liter) DC link capacitors.
