There is a gap between conducted EMI (waveform control and filter) and radiated EMI (shielding), particularly for wide band gap devices-based power converters. Current shielding effectiveness standards focus on the measurement of shielding effectiveness in the frequency domain, though some work has been done on defining and characterizing shielding in the time domain. There appears to be nothing in the literature relating to time domain on-board shielding. As part of the EU funded PARASOL project working on sustainable solutions for electromagnetic shielding in mobility applications, this task aims to further the understanding of on-board shielding for power electronics and provide tools to allow engineers to optimize this shielding. An innovative strategy to shield on-board EMI generated by power-electronic equipment will be explored. It consists of a holistic shielding technique including both software and hardware. This will enable a trade-off between waveform control (complexity and efficiency) and shielding techniques (mass and cost) in the overall on-board design. This trade-off will be assessed with respect to the SSbD approach.
