Analysis of Various Pickup Coil Designs in Nonmodule-Type GaN Power Semiconductors

open access: yesSensors, 2020
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

open access: yesJournal of Geophysical Research: Atmospheres, Volume 130, Issue 12, 28 June 2025.
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 ...

Time–frequency characteristics and influencing factors of the pressure wave caused by power–frequency arc inside a closed oil tank

open access: yesHigh Voltage, Volume 10, Issue 3, Page 699-709, June 2025.
Abstract The arc faults inside oil‐immersed power equipment can produce high‐amplitude pressure waves inside tanks, which might cause ignition and explosion accidents. This kind of failure is one of the most severe faults for power equipment and has attracted considerable attention in recent years.

Optimization of current sensors with Hall probe and Rogowski coil

open access: yes, 2022
The main aim of this thesis is to understand the working of 2 magnetic current sensors, the Rogowski coil and Hall sensor, and study the errors induced in these sensors due to geometrical asymmetries and changes in the position of the primary conductor.

A novel current‐source management integrated circuit applied to high‐voltage integrated gate commutated thyristor gate driver

open access: yesHigh Voltage, Volume 10, Issue 3, Page 533-545, June 2025.
Abstract This paper presents a fully customised integrated gate commutated thyristor (IGCT) gate driver monolithic integrated circuit (GDMIC), aiming to address the many shortcomings of traditional IGCT gate driver units composed of discrete components, such as the excessive number of components, low reliability, and complex development processes.

Calibration of Rogowski Coils at High Pulsed Currents

open access: yesNCSL International Workshop & Symposium Conference Proceedings 2013, 2013
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.
