Extended Wide-Bandwidth Rogowski Current Sensor With PCB Coil and Electronic Characteristic Shaper
IEEE Transactions on Power Electronics, 2021 Because of their fast switching speeds, current measurements for wide band-gap (WBG) devices have become increasingly challenging. Particularly, the designed current sensor must be nonintrusive and have a small size and a very wide bandwidth. One promising current sensor is the printed-circuit-board (PCB) Rogowski current sensor, whose bandwidth is ...

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.
