Short summary
For energy efficient power conversion, fast switching power semiconductors are used within power electronics. The switching can lead to disturbances of other electrical devices because of interference on the power line and in the air. The common aluminium heat sinks for the cooling of the power semiconductors are electrically conductive and lead to more interference. Using an electrically isolating ceramic heat sink is an approach to reduce the interference from the heat sink.
