A modified PSPICE model for the power PIN diode

In this paper, we present a modified approach for the modeling of power PIN diodes. The ambipolar diffusion equation (ADE) is solved numerically under various injection conditions instead of solving it under high-injection as usually encountered. The model is developed and implemented as a PSPICE subcircuit. To validate our model, comparisons between the results of the developed model with experiments are presented and very good agreement is observed.
