Rogowski coil transducer for magnetic compression solid-state pulse power based on Reverse Switched-on dynistor

In this paper, high frequency behavior of a Rogowski coil is analyzed. Considering the model of the coil frequency response, the damping ratio based on termination resistor can be used to divide the coil frequency band into three bands: derivation band, proportion band and resonance band. Corresponding outside integrator circuits are built according to characteristics of each band. A novel compound integrator circuit consisted of self-integration, passive RC integration and active RC integration is presented. The compound integrator improves the measurement upper bandwidth limit of transducer to the coil’s natural frequency. A transducer using a printing circuit board(PCB) coil of 100 turns is constructed with designed frequency of 10 Hz~17 MHz and sensitivity of 1 mV/A. The transducer is
