Abstract
In order to measure di/dt in the range of 10 to 20 kA/μs, air cored coils can be used. The coil´s natural frequency limits the bandwidth of this probe. PCB coils have a natural frequency of 10 MHz or more. Theoretical analysis and measurements with di/dt of 5 kA/μs and 500 A are presented, employing the PCB coil in a HOKA current probe
