Resumo (PT):
This paper presents a method for the solution of the Ambipolar Diffusion Equation (ADE) with a Finite Element (FE) approach. The method
enables the representation of the base region of power bipolar devices as combination of elementary two port networks with parameters that can
vary in time and space. This allows the solution of this equation through an equivalent electrical network. The method can be implemented into
any electrical circuit simulator becoming the core for power bipolar devices simulation. The application of the method in modeling power p-i-n
Diodes is presented. The results from simulation with SPICE are then compared with known experiments.
