For the 6th time Fraunhofer IZM was exhibiting at PCIM, the trade fair for Power Conversion and Intelligent Motion in Nürnberg. The focus of the presentation was on current IZM-research results and development trends from the realm of power electronics for e-mobility.

The institute presented methods for EMC-interference suppression in battery chargers for hybrid cars. We introduced an active leakage current compensation unit whose functions included preventing the FI switch activating during charging of an electric car. Also featured was a demonstrator for measuring the chip-junction temperature during operation.

 A further research area was combining good electrical and thermal properties of TIM (thermal interface material) layers in power electronic assemblies, especially in circuit board assembly. The first results of this research were presented at PCIM.
