Basic diode SPICE model extension and a software characterization tool for reverse recovery simulation

The paper describes the way of extending a basic diode SPICE model for a possibility to simulate realistic reverse recovery of power diodes. The proposed macro model uses all basic diode model characteristics and processes the diffusion capacitance current for adjusting reverse recovery. A Windows application tool was made to simplify creating a new diode SPICE sub-model using the manufacturer data sheet or measured data. Experimental data are presented for comparison of the proposed model and real diode reverse recovery.
