Abstract
This paper investigates the use of simulations of the electromagnetic emission (EMI) caused by the switching activity of a gallium nitride half bridge used in a power electronics application to predict the maximum generated conducted emission at the power supply lines. By using a simulation model of the voltage method defined in the CISPR25 standard, the important parasitic elements of the electronic components and the measurement setup are taken into account, but complicated modeling and simulation techniques are avoided. It shows that a simple circuit simulation is an effective alternative to predict emissions at an early design stage. Examples of simulation models and simulation setups as well as the measurement of the emissions are presented. The simulation data match the measurements well and provide a good estimate of electromagnetic interference already in the initial phase of new developments.
