Abstract :
An online temperature estimation method for IGBTs has been developed. It is based on the gate-emitter threshold voltage captured during the turn-on transient, which can be used as a temperature-sensitive electrical parameter. A dedicated measurement board directly connected to the power device was designed and tested in a high-power 4.5-kV IGBT module over its whole operation range.
