Abstract :
The work presented in this paper is concerned with the effects of a high temperature gate bias (HTGB) and a high temperature reverse bias (HTRB) stresses on non-punch-through IGBTs. The stresses were achieved during 1200 hours at 140degC. A particular interest was taken in the parameters related to the switching mode operation and experimental results on their evolution under the two types of stress are presented in a quantified way. A qualitative analysis of the switching times effects, due to the IGBTs ageing, on a pulse width modulation (PWM) inverter operation is presented
