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

IET 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 ...

Study on the issue of electric field concentration in submodule of press pack IGBTs

2017 Sixth Asia-Pacific Conference on Antennas and Propagation (APCAP), 2017
There is a phenomenon that the chips of press pack IGBT (Insulated Gate Bipolar Transistor) meet the requirements of withstand voltage test, but ignition sometimes occurred in the submodules of the same kind of press pack IGBT during the test. In response to this situation, this paper firstly analyzed that the difference of submodule frame lead to ...
