Analysis of Various Pickup Coil Designs in Nonmodule-Type GaN Power Semiconductors
Gallium nitride (GaN) devices are advantageous over conventional Silicon (Si) devices in terms of their small size, low on-resistance, and high dv/dt characteristics; these ensure a high integrated density circuit configuration, high efficiency, and fast

Underlying Physical Mechanisms in Upward Positive Flashes
Abstract This study presents the first observation of a mixed mode (MM) of charge transfer during an upward positive flash, which was initiated from the Säntis Tower in Switzerland. High‐speed camera footage, along with current and electric field measurements, revealed a downward‐propagating recoil leader connecting to the grounded current‐carrying ...

Calibration of Rogowski Coils at High Pulsed Currents
Calibration of Rogowski Coils at High Pulsed Currents. The many applications of Rogowski coils include their use as current sensors in AC resistance welding. Weld quality depends on monitoring/controlling the welding currents. The accuracy of these current sensors matters, and so does the accuracy of their calibration.
