近傍磁界強度分布に基づく大電流SiCパワーモジュールのEMI低減設計評価

抄録

This letter studies the design of electromagnetic interference (EMI) noise mitigation for large-current SiC power modules with integrated DC-link capacitors based on the visualized near magnetic field strength in a prototype power module wiring. This method verifies that symmetrically placed DC-link capacitors in a power module is effective in reducing MHz band-noise current.
