Abstract

Dampers are widely used in power electronics to damp resonances, in order to reduce device stress, power loss, and electromagnetic interference. In this paper we formulate the damping problem so as to expose the fundamental tradeoff between damping amplitude peaks and minimizing power dissipation, and then use a constrained optimization approach to compute optimal Pareto frontier as a function of damper order. We use the procedure to demonstrate the diminishing returns of increasing damper order using a simple filter example, and then we demonstrate the power of the method for multiport converters. In particular, we show that using the constrained optimization procedure dramatically outperforms the standard port-by-port method.
