IET Power Electronics, Volume 19, Issue 1, January/December 2026.This paper proposes a non‐contact method for measuring the turn‐off time of insulated‐gate bipolar transistor (IGBT) devices in modular multilevel converters (MMC) submodules, using the decay of load‐side common‐mode current. The technique leverages existing current‐sensing infrastructure and avoids intrusive modifications, enabling real‐time ...

IET Power Electronics, Volume 19, Issue 1, January/December 2026.Based on the principle of circuit equivalence, this paper proposes a decoupling calculation method for the coupled parasitic inductance matrix. This method transforms the self‐inductances and complex coupled mutual inductances in the traditional coupled parasitic inductance matrix into single equivalent parasitic inductances.
