Current Imbalance Monitoring in SiC-MOSFET under Unclamped Inductive Switching by Tiny PCB Rogowski Coil

Current Imbalance Monitoring in SiC-MOSFET under Unclamped Inductive Switching by Tiny PCB Rogowski Coil
We monitored the current imbalance in a SiC-MOSFET chip under unclamped inductive switching condition by using our printed circuit board Rogowski coils. The current imbalance varied significantly from sample to sample. The SiC-MOSFET with a larger current imbalance was destroyed with lower avalanche current than other samples.

Micro PCB Rogowski coil for current monitoring and protection of high voltage power modules [PDF]

Microelectronics Reliability, 2016
Abstract We have developed a printed circuit board Rogowski coil for monitoring of current and protection of high-voltage power modules and packages. It is small, thin, and inexpensive current sensor and is almost the ideal Rogowski coil because of its fishbone pattern.

High Bandwidth Integrator for Differential,PCB Integrated Rogowski Coils

2023 International Conference on Electrical Drives and Power Electronics (EDPE), 2023
This paper provides an accurate and high-bandwidth current measurement method, using a differential, PCB integrated Rogowski coil. This measurement is ideal for switching characterization of wide-bandgap semiconductors, which are progressively improving switching speeds of power electronic circuits and require a PCB design with low parasitic inductance.

The reliable design of PCB Rogowski Coil current transformer

2006 International Conference on Power System Technology, 2006
PCB Rogowski coil has a particular structure that interconnects the conductive imprints on the upper and lower sides of the each printed circuit board by plated through holes and connects printed circuit boards in series by soldering points. Once a plated through hole or a soldering point falls, PCB Rogowski coil opens and outputs incorrect signal ...
