High-Frequency Modeling of Power Semiconductor Devices
Research Guide
What is High-Frequency Modeling of Power Semiconductor Devices?
High-Frequency Modeling of Power Semiconductor Devices develops behavioral models for IGBTs and SiC MOSFETs that capture package parasitics and switching transients up to MHz frequencies for accurate EMC simulation.
Researchers validate these models using double-pulse testing and time-domain reflectometry to predict EMI in power electronics. Over 1,000 papers address related packaging and noise issues, with foundational work from Chen and Ling (1997, 318 citations). Recent advances focus on SiC devices and stray capacitance modeling (Shen et al., 2019, 92 citations).
Why It Matters
Accurate models reduce prototyping iterations in EV power modules by enabling predictive EMI analysis, as shown in Yang et al. (2020, 166 citations) on automotive packaging. They minimize power supply noise in high-performance drives (Chen and Ling, 1997, 318 citations) and support SiC integration for higher efficiency (Chen, 2017, 276 citations). This cuts design costs and improves reliability in traction systems (Jahns and Blasko, 2001, 173 citations).
Key Research Challenges
Package Parasitic Extraction
Extracting accurate inductances and capacitances from SiC MOSFET packages remains difficult due to complex geometries. Hou et al. (2019, 135 citations) highlight limitations of wirebonded schemes. Validation requires high-bandwidth measurements beyond standard scopes.
MHz Switching Transient Modeling
Capturing transients in SiC devices at MHz frequencies demands behavioral models beyond SPICE limits. Zhao et al. (2019, 137 citations) address active gate drivers for speed control. EMI prediction accuracy drops above 1 MHz without proper parasitics.
Parallel Device Current Sharing
Mismatched parasitics in paralleled SiC MOSFETs cause uneven currents and EMI spikes. Li et al. (2023, 91 citations) analyze mechanisms and solutions. Double-pulse tests reveal discrepancies not captured in average models.
