“…One of the most relevant aspects of this work is that it mainly emphasizes the phenomenon of radiated emissions with respect to conducted emissions. This strategy was adopted to tune the simulation flow using a complete set of waveforms and not a filtered one as it is usually performed by firstly minimizing conducted emissions and consequently also radiated ones [9,11]. This preventive filtering of conducted emissions risks makes less appreciable the levels of emissions radiated by the An accurate electromagnetic simulation flow that can predict radiative phenomena without the need for a physical prototype can be extremely useful, since alternatives can be evaluated at the design stage, thus avoiding redesign and fabrication costs, and time-to-market delays that are caused by an eventual failure of the compliance tests.…”

“…While electromagnetic simulation flows aimed at evaluating electromagnetic related phenomena were extensively studied in the literature [4][5][6][7][8], their specific application in IPEMs or power modules is less examined or often limited to electromagnetic compatibility (EMC) aspects [9]. In some cases, electromagnetic (EM) evaluation is performed through mathematical models able to predict EM interference (EMI) phenomena [4] or through a classical measurement approach [10] with all the issues related to the need for a prototype and an anechoic chamber.…”

The growing use of electric vehicles is requiring the implementation of power electronics applications with ever faster devices, such as silicon carbide (SiC) MOSFET, to reduce switching power losses and reach higher power density, with the final objective of improving performance and lowering the system cost. A side effect of such faster switching devices is the generation of high-frequency harmonics with significant energy, so their impact must be evaluated in terms of conducted and radiated electromagnetic interference (EMI). The optimal design of PCBs and filters for facing electromagnetic compatibility issues requires properly estimating the EMI level of different design solutions. Analysis of the current state of the art reveals that previous approaches can not effectively support a design focusing on a reduction in radiated EMI. To surpass these limits, the paper defines an electromagnetic simulation flow aimed at evaluating the radiative fields in the case of an integrated power electronics module operating in automotive applications and featuring fast SiC power devices. Then, the proposed simulation was applied to an LLC resonant converter featuring an STMicroelectronics SiC-based ACEPACK module. The work also highlights that future research efforts must concentrate on finding the best compromise between computational effort and estimation accuracy.
