An Automated Tool for Modelling Impedance for SPICE (ATMIS) with Focus on DC-Bias Dependent Behavioural Passive Component Modelling

This work deals with behavioural model generation for current or voltage dependent (DC-biased) passive components, namely inductors and capacitors. Key difficulties for DC-biased model generation are highlighted and a suitable model topology is selected. Also, an automated modelling tool has been developed to generate DC-bias dependent models from measurement data for SPICE-style simulators. Difficulties in the process of automated model generation are highlighted and solutions are proposed. Finally, an application case is presented, utilizing a DC-bias dependent inductor model in a simple time domain switching simulation.
