title = "Modular Simulation of Zonal Architectures and Ring Topologies for Automotive Power Nets",
abstract = "Current and future trends in the automotive environment show exciting new developments such as autonomous driving on the one hand and on the other hand require solutions for the associated challenges such as handling an increasing electrical power demand or the secured energy supply of safety-related components in all operating conditions. New power net topologies in ring structure enable the exploitation of new degrees of freedom with regard to aspects such as reliability and fault tolerance. However, there is a large number of degrees of freedom in the concrete dimensioning and structuring of the ring topology which have a lasting influence on the system behavior. Following the trend of zonal architectures, the number and configuration of Integrated Smart Distribution Devices (ISDDs), which act as highly integrated intelligent power distributors, can be varied. The hardware setup of these variably equipped units thus has a significant influence on the voltage and current distribution in the vehicle electrical system. Usually, this would have to be investigated building individual simulations. In contrast to this, a universal simulation approach using Dymola - Dassault Syst{\`e}mes{\textregistered} is introduced in this paper, which is able to cover all intended variations of power net topologies and hardware configurations. The designed simulation allows the evaluation of the overall system in all embodiments in a simple way and without having to adapt the form of the model. The structure of the simulation is examined in the following and the influence of the system setup on various key parameters is illustrated using selected examples.",
