Analyse und Bewertung leitungsgebundener Emissionen der Elektromagnetischen Verträglichkeit in Umrichtern und Erstellung eines Simulationsmodells zur Verifikation

Aim of this thesis is the development of virtual simulation models of converters to be used during the design process.

Therefore, the electromagnetic interference emission (EMI) of three converter generations of one converter topology in the complete drive system is investigated.

Structural and functional major interference sources and appropriate actions for interference elimination are defined and described in the thesis and integrated in the simulation models.

In the simulation model of the most recent converter generation, the actions for interference elimination are then deliberately designed independent of the hardware. That means, they eliminate interferences to the same amount but in a potentially more cost-efficient way than today’s filters.

The result of this simulation model is implemented and verified in real hardware.
