One-dimensional analysis of dynamic behavior of a thyristor

The dynamic behavior of a thyristor is numerically analyzed by solving a one-dimensional Poisson´s equation and one-dimensional time-dependent continuity equations. The calculated results of the gate turn-on, dv/dt triggering and reverse recovery characteristics are compared with the experimental results. The advantage of this one-dimensional analysis method is that the dynamic characteristics of a thyristor with an arbitrary shorted emitter resistance and an arbitrary impurity profile can be analyzed.
