Abstract :
A special-purpose program for long-term digital simulation of power electronic circuits, KREAN, is presented. Particular attention is given to simple device modeling for long-term simulation, solution of stiff power electronic circuits (simultaneously having large and small time constants), solution of large sparse circuit matrices, and handling of discontinuities in switched power electronic circuits. This work has been undertaken to present an attractive alternative to general-purpose programs like SPICE and EMTP.<>
