Abstract :
The switching behavior of a gate turn off thyristor with a shorted
anode emitter has been calculated numerically by solving the
semiconductor basic equations in an 'equivalent' one-dimensional
model device. Taken into account are all significant physical
semiconductor mechanisms and the interaction with a nonideal
external circuit is considered. Computations, using this model, are
made on microcomputers and successfully compared with the results of
measurements conducted at the INRETS's LTN-laboratory on a number of
anode shorted GTO's of different origins. Short circuits between
anode emitter and N-base are taken into account by an additional
term in the electron recombination rate. It is shown that the
calculated switching behavior for a given device remains accurate
when the external circuit is changed. The computational time of a
turn-off simulation is approximately 40 minutes with a personal
computer such as IBM-PC's or Macintosh II's. Owing to the results
obtained and the accurate description of the tailing current
waveforms on a number of GTO's with different circuits of operation,
such a simulation model is found to be a valuable tool for circuit
design and device selection.
