Electromagnetic compatibility - short EMC - touches many areas of technology.

In order to avoid unnecessarily many filters within the EMC, it is important to reduce the electromagnetic emissions even at the point of their formation. Intelligent EMC can drive the use of efficient power electronics on a broad scale and open up significant energy potentials, e.g. the avoidance of conversion losses in the industrial sector.

Project targets

Minimization of the material effort required to reduce the electromagnetic interference emission of power electronics in electric vehicles

Challenges

Development of passive measurement methods for the early assessment of EMC behavior

Ltspice modeling of power modules taking into account parasitic elements

Characterization of CM currents using mathematical models (Ltspice)

Layout design for optimizing the disturbance behavior

Results

Deeper understanding of the disturbance model as well as the development of a simulation tool for the early electromagnetic evaluation of power electronics.

Development of a newly developed passive measuring method, which enables the evaluation of partial components in the prototype stage.
