Layout modelling to predict compliance with EMC standards of power electronic converters

In power electronics, the layout of a converter is known to have a significant impact on its conducted emissions. This paper focuses on layout modelling in order to predict converter compliance with EMC standards before prototype manufacturing. Inductive effects and capacitive parasitic effects should be considered and models in the form of equivalent circuits are required by time domain simulators. In recent works, a software was used to obtain an equivalent circuit of the inductive effects and analytic calculations were performed to add equivalent capacitors. In this paper a single software is used to generate a model which includes both capacitive and inductive effects. The existing method and the proposed one show very similar results and fit well with experimental results. The proposed method requires less efforts and is more scalable since it can be applied to complex geometries.
