In this chapter, we discuss the simulation of a conducted emission test for an inverter—the same inverter for which we designed a filter in the previous chapter. We begin by examining the functional circuit of the inverter and outlining the steps required to build a coupled EM-circuit simulation model. For transient circuit simulation, the circuit model extracted from the EM simulation must be both passive and causal. Therefore, we introduce the process of vector fitting, which generates passive and causal macromodels from EM simulations. Further details on this process are provided in the advanced section. Next, we explore various approaches for modeling the electric motor in the conducted emission simulation and discuss how these models are integrated into the EM simulation. In the final part of the chapter, we analyze the impact of design choices on conducted emissions.
