Application examples of power semiconductor modules (or DC/AC converters) are in industrial drive technology, solar inverters or in the powertrain of electric vehicles. Developing heat is dissipated from the modules by metallic heat sinks. This prevents any rise in temperature and helps to ensure an optimum operating temperature.
The power semiconductors are protected from external influences such as moisture, dirt, and fluctuations in temperature by a housing made from the thermoplastic Ultradur.
Ultradur B4450 G5 is noted for the fact that it is very effective in helping to prevent electrolytic corrosion: metal contacts which are installed are only affected to a minimal extent even under highly humid and warm conditions. This means that short-circuits and the damage resulting from this can be avoided.
