“…Unfortunately, both methods do not offer galvanic isolation, which potentially could lead to undesired CM distortions due to the extremely fast fault transients. Alternatively, the device current could be measured galvanically isolated with a Rogowski coil [48], which is, however, sensitive to external electric and magnetic fields and could therefore lead to false triggering.…”

“…Alternatively, the sensed currents can be compared with a threshold for rapid detection of over-currents caused by shortcircuits. It is therefore a helpful way for protecting the IGBTs, as explained in [45] [53]- [55]. Protection of the IGBTs may however not be the only objective.…”

Latest wide-bandgap power devices are switching progressively faster compared with existing silicon devices. Their accurate current measurements for either control or protection have therefore become tougher. One method, that can fulfill the requirements, is to use a Rogowski coil and its accompanied electronics to form a Rogowski current sensor with high bandwidth, small volume, low cost and ease of integration. This paper therefore aims to review various aspects of the Rogowski current sensor from its history, measuring principles to modern power-electronic applications. The applications have, in turn, motivated a progression from traditional helical to recent miniaturized printed-circuit-board (PCB) implementation, in order to improve the overall power density. This progression has similarly been reviewed, together with its various design aspects applied to the winding, integrator, shielding, and parameters of the Rogowski current sensor. Future challenges and directions are then summarized, whose ultimate goal is to maximize accuracy over a wide bandwidth without being affected by radiated and near-field-coupling interferences.

“…In 2011 and 2013, D. Gerber, T. Guillod designed a PCB Rogowski coil with a coil bandwidth of more than 28 MHz and a time delay of 11 ns for over-current detection of a 4.5 kV PPI gate drive circuit. In this paper, the equivalent model of Rogowski coil and the prediction of parameters are established, and the accuracy of prediction is verified by measurement [14,15]. In 2013, Dr. Xiang Minjiang designed a passive and active composite integrated circuit with a bandwidth of 10 Hz~1 MHz for the acquisition of traveling wave signals in intelligent substations [16].…”

Recently, the press-pack insulated gate bipolar transistor (IGBT) has usually been used in direct current (DC) transmission. The press-pack IGBT (PPI) adopts a parallel layout of boss chips, and the currents of each chip will be uneven in the process of turning on and off, which will affect the reliability of the device. To measure the currents of each chip, based on the analysis of the principle and equivalent model of the Rogowski coil, this paper puts forward the design scheme and design index of multi-layer printed circuit board (PCB) Rogowski coil with good high-frequency performance, strong anti-interference ability and sufficient sensitivity. With the simulation analysis of Altium Designer and ANSYS softwares, a 1 mm thick, 76-turn integrated four-layer PCB Rogowski coil is designed. Then, adding a composite integrator, an integrated Rogowski coil sensor for measurement of PPI chips currents is designed. The Pspice simulation and the experiment results show that the sensor is fully satisfied with the chip current measurement.
