A Multi-level simulation using VHDL-AMS and coupled analysis for an alternator regeneration system in a vehicle

Recent innovation in vehicle systems has brought the extensive application of power electronics (PE) technology, which in turn has made the system more complex. The vehicle system is a multi-domain system, so that computer simulation has become an indispensable tool for vehicle system analysis. We propose a simulation method for the complex vehicle system based on the VHDL-AMS language. A multi-level modeling technique for an alternator regeneration system is also proposed using VHDL-AMS and coupled analysis with the aim of analyzing the simulation of the regeneration system in detail.
