GaN in Space

Focus:

This article discusses the use of GaN power devices, mainly those from Freebird Semiconductor in power systems for space applications. Before discussing the power performance capabilities and rad hard characteristics of the GaN power transistors and the topologies in which they are used, the article points out the opportunities for GaN devices by describing the different components of space power systems (energy sources and storage, power distribution architectures, and power converters) and power specs for satellites and spacecraft including examples from existing and planned programs.
