Recently, the virtual development of automotive power systems is gaining importance justified by increased functional requirements to safety-relevant components. In order to accurately simulate both transients such as short circuits and driving cycles, models of system integrated components need to satisfy a wide frequency range. Complex models of electromechanical actuators and high frequency switching power electronic devices need to be calculated. In order to reduce the computation effort needed, models of delimited validity are developed. This article introduces impedance spectroscopy in automotive electrical power systems as validation method for differentiated models. Moreover, the validation method is tested with a developed power electronic pulse injection device on a vehicles power net.
