Power Module Design for GaN Transistors Enabling High Switching Speed in Multi‐Kilowatt Applications
A novel power module design comprising a 650 V, 300 A half‐bridge with integrated direct current (DC)‐link and gate drivers is presented. It has an exceptionally low power loop stray inductance of 1 nH. Simulations show a maximum dv/dt of 232 V ns−1 without parasitic turn‐on. The drain–source voltage overshoot amounts to only 19% of the DC‐link voltage.

Compared to Si‐IGBTs, SiC MOSFETs bring higher efficiency, higher power density, and smaller size and mass to electrified vehicle application without increasing system cost. Stronger electromagnetic interference, reliability issues, potential motor insulation failure, and heat dissipation issues are the main technical challenges.

A novel inductively coupled RLC damping scheme for eliminating switching oscillations of SiC MOSFET
A novel inductively coupled RLC damping is proposed to eliminate switching oscillations of SiC MOSFET. The proposed scheme is less insensitive to parasitics enabling selection of snubber resistors with higher power ratings. It also avoids unusual temperature rise resulted by snubber losses in the power loop.
