Abstract :
A SPICE model of power PiN diodes is presented, based on the solution of the ambipolar diffusion equation through the finite difference method. The model is validated against experimental characterizations of commercial devices for on-state and reverse-recovery operation. Simulation examples of practical switched-mode power supplies (SMPS) are provided, in order to demonstrate the model effectiveness, speed and convergence properties
