Continental-ISAD Landsberg am Lech  

EMC engineer for the innovative REDBOX concept in boiling-fluid technology

Special challenge: rapid EMC modifications to closed, hot power electronics inside pressurized enclosures

Solution: Measurement of power electronics without boiling-fluid (i.e. air-cooled) within milliseconds

Programming the software for triggered measurements and for the partitioning into small sections (of e.g. 400 ms)

Triggering via a threshold value detector (current or voltage) with adjustable start-up delay (e.g. 100 - 200 ms)

==> reduction of the possible change period of 1 change per Day ==> to 10 changes per day
