Behavioral model for solid-state power controller

This article describes and confirms a behavioral model of the SSPC. This model includes switching state and steady-state behaviors, and it also has implemented the I²t curve and the overload and the short-circuit protection functionalities. The proposed model is based on experimental measurements and information provided in the manufacturers´ datasheets. Further, the behavioral model can be parameterized for different SSPCs, and its features are better tailored for the simulation of large PDS in comparison with structural models. Thus, this model permits improving the convergence and simulation times for large PDS. Finally, the SSPC behavioral model has been parameterized and validated by means of simulations and experimental results with different commercial SSPCs.
