A Test Bench for Thermal Characterization of IGBT Power Modules Over Mission Profiles
For thermal stress validation and lifetime estimation of power electronic modules data obtained during realistic operation is crucial. For this reason, the thermal characterization of IGBT power modules over mission profiles is discussed in this paper. A test bench is introduced, which allows to apply realistic loads to an IGBT power module, which occur for example during a mission profile of an electric vehicle.
Floating Gate Method to Protect IGBT Module from Explosion in Traction Converters
A method using floating gate is suggested to avoid explosion of IGBT modules in converters by redirecting the fault current through good chips in the module and reducing the current concentration in the faulty chip. The proposed method was able to avoid explosion of various tested IGBT modules at a short circuit energy of 7.2 kJ and/or 16.2 kJ in a test set up.
A Condition Monitoring System for Power Semiconductors in Wind Energy Plants
With the increase of renewable energy power plants, the amount of power converters increases also. Changes in temperature and humidity due to operation and environmental conditions result in a degradation of the semiconductors. Currently data is collected in an active, commercial wind farm to find events and conditions which have a major impact on the degradation. For the longtime recording a flexible measurment system was build. Now the measurment system will be extended by an online monitoring system based on a lifetime prediction model.
