Optimal design of active EMC filters

[摘要] A recent trend in automotive industry is adding electrical drive systems toconventional drives. The electrification allows an expansion of energysources and provides great opportunities for environmental friendly mobility.The electrical powertrain and its components can also cause disturbanceswhich couple into nearby electronic control units and communication cables.Therefore the communication can be degraded or even permanently disrupted. Tominimize these interferences, different approaches are possible. Onepossibility is to use EMC filters. However, the diversity of filters is verylarge and the determination of an appropriate filter for each application istime-consuming. Therefore, the filter design is determined by using asimulation tool including an effective optimization algorithm. This methodleads to improvements in terms of weight, volume and cost.
