PCB Rogowski Coils for Capacitors Current Measurement in System Stability Enhancement

Electronics, 2023
In terms of high-current measurement of capacitors, PCB Rogowski coils have attracted much attention because of their small size and easy installation. However, they are vulnerable to electromagnetic interference. In order to improve the immunity of the coil, this paper studies the influence of the structure and parameter changes of the double-layer ...

PCB Rogowski Coil sensor by using Saw blade pattern for arcing fault detection

Journal of Physics: Conference Series, 2023
Abstract Rogowski is a special current transformer and has been categorised as a low-power stand-alone current sensor. This sensor is designed by using a Saw blade pattern with 50 turns and 100 turns. This number of turns will impact the increment of the sensitivity of the sensor.

A review of silicon carbide MOSFETs in electrified vehicles: Application, challenges, and future development

IET Power Electronics, Volume 16, Issue 12, Page 2103-2120, 16 September 2023., 2023
Compared to Si‐IGBTs, SiC MOSFETs bring higher efficiency, higher power density, and smaller size and mass to electrified vehicle application without increasing system cost. Stronger electromagnetic interference, reliability issues, potential motor insulation failure, and heat dissipation issues are the main technical challenges.

A novel inductively coupled RLC damping scheme for eliminating switching oscillations of SiC MOSFET

IET Power Electronics, Volume 16, Issue 9, Page 1486-1498, 24 July 2023., 2023
A novel inductively coupled RLC damping is proposed to eliminate switching oscillations of SiC MOSFET. The proposed scheme is less insensitive to parasitics enabling selection of snubber resistors with higher power ratings. It also avoids unusual temperature rise resulted by snubber losses in the power loop.

Overview of monitoring methods of press‐pack insulated gate bipolar transistor modules under different package failure modes

IET Power Electronics, Volume 16, Issue 4, Page 683-698, 18 March 2023., 2023
Abstract Press‐pack insulated gate bipolar transistor modules (PP‐IGBTs) have been widely used in high‐voltage and high‐power‐density applications, such as high‐voltage direct‐current (HVDC) converters, because of their advantages of low thermal resistance, double side cooling, and short‐circuit failure mode.

Designing and manufacturing of electric arc furnace currents measurement system in Mobarakeh Steel Company by printed circuit board‐type Rogowski coils

IET Science, Measurement &Technology, Volume 16, Issue 6, Page 353-366, August 2022., 2022
Abstract This paper deals with the utilization of printed circuit board Rogowski coils (PCBRCs) for differential protection of electric arc furnace (EAF) transformers in Mobarakeh Steel Company (MSC), Isfahan, Iran. Because of a high level of current (in the range of 100 kA) in the EAF transformers in the MSC, employment of differential protection is ...

A digital‐controlled gate charge detection circuit for short‐circuit protection and condition monitoring of SiC MOSFET

IET Power Electronics, Volume 15, Issue 6, Page 476-486, 6 May 2022., 2022
Abstract The safe and reliable operation of power converter requires a protection circuit with fast response when the power device is subjected to the short‐circuit (SC) fault. In addition, the on‐line condition monitoring circuit is beneficial to provide a suggestion for the replacement of aged device.
