An Accurate On‐State Voltage Measurement Circuit for Chip‐Level Junction Temperature Monitoring of Press‐Pack IGBT

open access: yesIET Power Electronics, Volume 19, Issue 1, January/December 2026.
This paper proposes a novel on‐state voltage measurement circuit (OVMC) for accurate online Vce extraction. By adopting a power‐balanced differential diode topology, the proposed circuit minimises the Vce measurement error. The OVMC is applied to the Buck operating condition to monitor the junction temperature of chips inside a press‐pack IGBT ...
