摘要：

Modern power electronics devices like wide-bandgap semiconductors allow for higher switching frequencies compared to existing silicon devices. Measuring the switching currents in those systems requires a wideband-width current measurement sensor. However, available measurement systems require modifications of the PCB due to their size and introduce therefore parasitics into the system or are limited in bandwidth. This paper deals with the design and development of an Rogowski coil based current sensor, which allows for a low parasitic measurement of the switching current in a semiconductor device. The sensor is mounted on an adapter board, which is placed between the component and the PCB. Shielding and the geometry of the windings provide good suppression of interfering adjacent currents. Together with a wide-band integrator, fast transients in the nanosecond range can thus be measured. Experimental verification shows good agreement with the simulation. In future applications, the system can be implemented in integrated solutions allowing an on-chip measurement.
