Chair of Power Electronics

Setup for Thermal Characterization

The laboratory of the Chair is equipped with a setup for Thermal Characterization of Power Electronic Converters (TC-PEC). This setup enables the thermal characterization of power electronics in real operating conditions which is relevant for a cost effective system design and can be used for lifetime prediction of the components. The voltage range of the equipment enables tests for low voltage and medium voltage devices. The setup consists of:

  •  A high speed Infrared Camera with positioning system (355 Hz sampling frequency for 640x542 pixel)
  •  An Optic fiber temperature measurement system (8 channels, sensor response times up to 5 ms)
  •  DC power source (4 kV, 60 kW)
  •  AC power source (45 kW)
  •  Electronic loads
  •  Power analyzer with 6 channels
  •  A 12 Bit Oscilloscope


New High Speed Thermal Measurement System for Semiconductor Reliability Analysis


The overall setup is managed by a control and synchronization system, which controls every component and merges the measurements.



 Setup for Thermal Characterization


  • 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.
