In a modern hybrid vehicle where several switched converters are connected to a common high voltage DC-bus, current and voltage harmonics will arise due to the switching events in the inverter. In order to determine the behavior of the complete system, models that include switching characteristics, control parameters of each device and high frequency behavior of the cabling and the battery must be incorporated. The complete system model can then be used to e.g. quantify ripple components and analyze resonance effects. In this paper, a model of a drive system is set up and the results are verified by measurements. The model is then used to verify the interaction of the different subsystems and to investigate the complete system behavior. It is concluded that interaction of the different systems can be foreseen and that the battery inductance in combination with the DC-link capacitance contribute most to the DC-bus current ripple.
