Automotive high voltage components are developed and tested independently regardless to the system they are implemented in. The first system test is not performed before all components are implemented in a real car setup. This paper describes a modelling and simulation method to verify the intra system compatibility of each component to ensure their proper operation regarding control loop stability and EMC within the high voltage grid. The models used are gained from real component measurements to create a black-box equivalent containing sufficient information for a system simulation without requesting too much information which is under supplier's intellectual property.
