In a world challenged by global warming decarbonization became the most pressing task for our generation. In the light of this power electronics and the underlying semiconductor technologies are an essential tool for survival. In this sense GaN, SiC and Si are the three lucky stars of power. While all three technologies are inevitable for our future, each has its distinct character and use case. Starting with a recap of properties and manufacturing aspects, global trends for use cases and markets will be covered. A special focus will be on technology fusion (e.g. Si’C) to tackle conflicting requirements in power electronics.
