Computer based simulation for optimizing overvoltage protective devices for low voltage applications

This paper is part of an ongoing research in the design of SPICE Models for the simulation of nonlinear protective devices. These simulations are used to verify, in a nondestructive way, the behavior and characteristics of new or improved protective circuitry. Manufacturers as well as end-users have long seen the benefits of giving special importance to simulations as part of their design criteria in order to fulfil electromagnetic compatibility standards and industrial regulations. The ultimate goal of this conducted research is to establish accurate models of existing protective devices such as metal oxide varistors, spark-gaps and transient voltage suppressor diodes
