Simulation of a high voltage system in a hybrid electrical vehicle

In modern hybrid electrical vehicles (HEV) the electrical system includes different voltage levels. Visualization of the electric quantities such as currents and voltages of a high voltage system under load conditions is presented in this paper. Different strategies of electric component modeling such as machines or power electronics are used for an intensive analysis of the electrical system. Evaluation of the DC-link with respect to transients and feedbacks resulting from operational performance or fault operation is done.
