Pa. Mawby et al., RECOMBINATION AND JOULE HEATING EFFECTS IN GTO THYRISTORS WITH SPATIALLY VARYING LIFETIMES, IEE proceedings. Circuits, devices and systems, 141(4), 1994, pp. 292-298
In the paper the forward conduction characteristics of the GTO thyrist
or are studied. A two-dimensional simulation is performed which solves
the semiconductor device equations self consistently with the equatio
n for lattice heat conduction. The significance of the different recom
bination mechanisms and spatially varying lifetime is considered, alon
g with the relative effects of different mobility models. An experimen
tal comparison with a 2.5 kV device is made and good agreement is foun
d. The effects of heat dissipation in the structure are also considere
