The team of Princeton Fusion Systems, Princeton University, The National Renewable Energy Laboratory (NREL) and United SiC, will develop high efficiency, long life power electronics for fusion reactors.
Princeton Fusion Systems received this competitive award from ARPA-E’s Galvanizing Advances in Market-aligned fusion for an Overabundance of Watts (GAMOW) program, working to close multiple fusion-specific technological gaps that will be needed to connect a net-energy-gain “fusion core,” once it is ready, to a deployable, commercially attractive fusion system.
Fusion power plants will need efficient, high-power electrical drivers for plasma heating, compression, and control. Wide-bandgap (WBG) semiconductor devices and innovative amplifiers may speed up the development of fusion systems and reduce their eventual cost of electricity. Princeton Fusion Systems will develop prototype, high efficiency switching amplifiers using WBG SiC devices and amplifier boards that employ advanced cooling and digital control. The project will design, test, and qualify individual circuit boards as the building blocks for various short-pulse, long-pulse, and continuous-wave electrical-driver power supplies for fusion-energy systems.
We will also be developing power electronics that can be used in many power applications such as DC/DC converters and inverters.
