Power p-i-n diode modeling using SPICE

A physics based model for the power p-i-n diode is implemented into the general circuit simulation package SPICE. This model based on a variational formulation and finite element solution of the semiconductor equations accurately describes the forward and reverse recovery as well as the conduction behaviour. The procedure used to implement the resulting model into SPICE is described. The simulations are finally compared with known experiments for demonstration of its effectiveness.
