iPES-Thermal (Thermal Problems in Power Electronics)

In this educational module thermal effects being important for the dimensioning and operation of power electronic converters In connection with the increasing requirements on the power density and reliability of power electronic a basic understanding of thermal problems will become more and more important for the engineer. Besides basics we also provide applets visualizing effects like thermal runaway and paralleling of power semiconductor devices. Further applets will be added, and translations into other languages than English will be provided in the future.
