  abstract     = {{Electromagnetic compatibility (EMC) is essential for power electronic converters to prevent electromagnetic interference (EMI). Traditional post-design EMC testing is costly and time-consuming, motivating a shift toward model-based EMC (MB-EMC) with proactive EMI prediction. This thesis develops a simulation methodology for conducted emissions from an IGBT-based three-phase voltage source converter (3VSC) in the 150 kHz to tens of MHz range.

The converter’s high-frequency behavior was examined under various grounding and component configurations using continuous operation and double-pulse tests (DPT). A sensitivity analysis identifies dominant parasitic coupling paths across frequency ranges. With a grounded heatsink, a common-mode path emerges, and heatsink parasitic capacitances and line filter inductors primarily determine lower-frequency oscillations in the 600 kHz range. Leaving the heatsink ungrounded shifts the lower-frequency oscillation to 1.35 MHz, which the model fails to reproduce, highlighting a differential-mode modeling gap.

At tens of MHz, oscillations are dominated by parasitic inductances, including unmodeled IGBT package inductances. Doubling modeled DC-link inductances as a proxy for IGBT package parasitics reduced the simulated resonance, improving measurement agreement. The DPT reduced average simulation time from 63.7 to 3.4 minutes, saving 60.4 minutes per test. This work provides a robust workflow for characterizing critical parasitics from board to package level, enabling early-stage conducted EMI prediction and a proactive power electronics design process.}},
