Busbar Interference Correction for Non‐Invasive Current Distribution Sensing in Press‐Pack IGBTs
IET Power Electronics, Volume 19, Issue 1, January/December 2026.This paper proposes a busbar‐interference correction method for non‐invasive sensing of internal current distribution in press‐pack IGBTs under converter‐valve conditions. By using state‐differential magnetic‐field reconstruction, the method suppresses common‐mode interference from side busbars and improves current‐offset direction identification ...

Droop and Offset Error Suppression Method for a PCB Self‐Integrating Rogowski Coil Sensor
IET Power Electronics, Volume 19, Issue 1, January/December 2026.This paper proposes a droop and offset error suppression method for a PCB self‐integrating Rogowski coil sensor used in power converters condition monitoring. By optimising the self‐integrating integrator circuit parameters, the method reduces the droop rate of a 50 µs pulse to 3.9% and limits offset voltage to within 5 V. The improved accuracy enables
