In modern Power Electronics systems high switching
frequencies are employed to increase power density,
but EMC filter components are responsible for a large
volumetric occupation of the power system. In some
cases the EMC filters required to fulfill EMC
regulations cover more than 30% of the total system
volume. In a world where space gets expensive, the
volumetric reduction of the components in EMC filters
is of great importance aiming for reduced dimensions.
This work proposed modeling techniques for the
generation and propagation of conducted emissions in
three-phase converters and filter concepts aiming to
meet EMC standards and reduce the volume of the EMC
filters.
Optimizing EMC filters requires several steps to be
performed, which are described here focusing on
three-phase PWM converters.
Finally, a discussion quantifying how much filters
strongly impact the volume of three-phase PWM
converter systems is preformed.
