It is a commonplace that high voltage and humidity do not go together well. Even if the reduced insulation capability does not directly lead to a breakdown, mechanisms like surface discharge, corrosion and ion movement can take place and can eventually lead to a breakdown anyway. Power electronics components, especially IGBT-modules but also others like capacitors, bus bars and circuit boards, are not hermetically sealed. They can take up considerable amounts of moisture and degrade over time.
Of course, the progress of degradation depends a lot on the climatic conditions in the electronics compartment. Usually, it is not air-conditioned and, in some situations, even condensation can occur. With power electronics conquering more and more applications and regions, e.g. offshore wind power, photovoltaic in the tropics or railway in developing countries, the situation is becoming more challenging.
This workshop will give an overview of critical application conditions and will focus on individual humidity issues occurring in the field. In addition, there will be an overview of degradation mechanisms occurring in different components and there will be a compendium of the respective dynamics and their modelling. The workshop will also try to match the component capability with the application needs and vise-versa. What capability is required and what condition has to be avoided by the application?
This way, the workshops brings together the experts of a wide range of fields ranging from applications to material science. Practitioners will get the chance to review the latest scientific results and the scientists will be able to obtain first hand input from the field. Thus, the workshop aims at a better understanding along the value chain. It is also well suited to get an overview, i.e. for professionals from the industry and researchers.
All presentations and discussions will be in English language.
