PCB Rogowski coils for high di/dt current measurement
2000 IEEE 31st Annual Power Electronics Specialists Conference. Conference Proceedings (Cat. No.00CH37018), 2002In order to measure di/dt in the range of 10 to 20 kA//spl mu/s, 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//spl mu/s and 500 A are presented, employing the PCB coil in a HOKA current probe.
