Abstract

This paper treats the problem of electromagnetic interference in switched mode power supplies using co-simulation. Co-simulation combines full-wave EM solution with non linear SPICE circuit. Voltages, currents (at different nodes in the circuit) that drive the EMI can be simulated. Different co-simulation strategies are discussed along with their pros and cons. Also different commercial software tools have been evaluated for this simulation technique and promising results have been compared to measurements of voltages, TEM cell coupling and coupling to an antenna. The circuit investigated is a DC-DC buck converter.
