초록
This paper presents an averaged switch model for an on-line deterioration analysis of inverters. The model is based on the operational characteristics of power diodes and IGBTS. Switching loss mechanisms are described and divided into the diode reverse-recovery mechanism, the IGBT current-tailing phenomenon, the IGBT turn-on time, and the output capacitances of the IGBTS and diodes. The deterioration analysis parameters are derived from the averaged switch modeling and the parameters can determinate the deterioration of the inverters.
