Abstract :
The IGBT is a critical device in the static converters, it is important to assess its reliability. In this paper, we investigate the accelerated aging effect on the conducted EMI (ElectroMagnetic Interferences) evolution in the N Chanel IGBTs. We propose a new aging method applied to the IGBT switching in the buck converter circuit (chopper series type), while applying a high current, in order to achieve a junction temperature (Tj) exceeds the highest maximum value specified by the manufacturer. The conducted EMI evolution is examined and presented before and after aging tests. The measurement results show that the obtained variations after aging tests are only on the conducted EMI amplitudes.
