| Popis: | This paper introduces and validates a measurement technique to detect and quantify condensation in a power module by means of a stray-field capacitor sensor. We apply this sensing technique to investigate the hypothetical use case of a railway application, which triggers measurable condensation on the silicone gel surface of the power module. Using this as a reference, we introduce the concept of combining a cyclic chamber profile with a thermal mass. It is shown that the thermal mass has a significant impact on the thermal profile of the device under test (DUT) and on the observed condensation. The paper explains how the railway use case can be simulated by optimizing the test configuration, and how a validation of power modules with respect to condensation conditions can be achieved. |
