Micro PCB Rogowski coil for current monitoring and protection of high voltage power modules
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.
