Active thermal control of power semiconductor modules

The aim of this project is to increase reliability and lifetime of power semiconductor modules in power converters using active thermal control, without affecting the system performance. The first milestone is the design of an online junction temperature estimation on the basis of temperature sensitive electrical parameters (TSEP). The second milestone is to introduce an aging model to monitor the impact of temperature fluctuations on the module’s lifetime. In the end the model predictive control is used to include thermal and aging information to the control law and set the op-timal switching operation that fulfils the applications demand, reduces the thermal stress in a specific semiconductor and limit the additional losses.

  • Our research is focused on the design of high efficient and reliable PWM-based power converter architectures (single-cell, multi-cell, multilevel), their modelling and control to exploit commercial as well as new power semiconductor devices with minimum over design.
    We develop controllers for electric drives and we are particularly skilled in the integration of renewable energy systems into the electric grid.
