AN INTERVAL METHOD FOR FINDING ALL OPERATING POINTS OF NONLINEAR RESISTIVE CIRCUITS

A new method for finding the set of all d.c. operating points of non‐linear electronic circuits is suggested. it is applicable in the case where the circuit equations are written in the hybrid‐representation form. In the general case, the non‐linear elements involved may be described by non‐monotone continuous characteristics. The method suggested is based on interval analysis techniques. Unlike other non‐interval methods, this approach guarantees that all operating points will be found within prescribed accuracy in a finite number of steps. The computational efficiency of the present method is illustrated by a numerical example. Copyright © 1990 John Wiley & Sons, Ltd.
