Limits of the quasi-static approach for calculating radiated emission from Power Electronics Converters

Abstract

With the increase of switching frequencies in power electronics converters, the range validity of circuit models must be more and more larger. A useful method for interconnect modeling is the Partial Element Equivalent Circuit technique. The model given by this technique can be combined with other circuit models (like transistors) into an input circuit for a circuit simulator. This technique can be used when the quasi-static hypothesis is verified. In the other case, this technique can be extended in order to include propagation and retardation. In this paper, we will try to carry out the limits of the quasi-static approach
