Invited Lecture: Trends in Power MOSFET Technology for Space Applications

Abstract: This report first briefly introduces the basic knowledge of power MOSFETs, including device structure, main parameters, and reliability issues. Then, an introduction will be given to the satellite power system and the anti-radiation power MOSFETs used in it, including the architecture of the satellite power system, the anti-radiation capability requirements of power MOSFETs used in space environments, and the current situation of major anti-radiation power MOSFET products at home and abroad. Finally, based on the development trends of low Earth orbit satellite constellations, especially future computing power satellites, we will discuss the cutting-edge technological needs of the industry and the fundamental technical issues that urgently need to be addressed.
