I want to model a varistor using the functional description given by the manufacturer Littelfuse for PSPICE. The characteristic of the Varistor is modeled as a power function combined with a linear behavior around current zero. I use a variable voltage source which is controlled by the current through itself. It is clear that that is an algebraic loop, but the error message that I get don’t show me where the problem is in detail.
