摘要

In a modern hybrid vehicle where a traction inverter is connected to a high voltage battery, current and voltage harmonics will arise due to the switching events. In order to determine the high frequency system behavior, simple analytical models are no longer adequate due to difficulties in parameter estimation. In this paper, a co-simulation model of a drive system is implemented in Ansys Maxwell/Simplorer and the results are verified by measurements. It is concluded that the machine model affects the system performance to such an extent that a co-simulation of the electric and magnetic domain is needed to capture all relevant effects on the DC-bus of the system.
