Power Module Design for GaN Transistors Enabling High Switching Speed in Multi‐Kilowatt Applications
Energy Technology, Volume 11, Issue 12, December 2023., 2023 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.

A novel inductively coupled RLC damping scheme for eliminating switching oscillations of SiC MOSFET
IET Power Electronics, Volume 16, Issue 9, Page 1486-1498, 24 July 2023., 2023 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.
