Radiation Hardened High Voltage GaN Technology to Enable a Permanent Human Presence on the Moon and Beyond

The sustained human presence on the Moon will require a highly available and reliable power system comparable to modern terrestrial utility grids. This system must provide effective fault isolation, autonomous protection, and coordinated operation across multiple distributed sources and loads. These elements will be separated by distances ranging from hundreds of meters to several kilometers, and under these conditions low voltage distribution is not viable. Transmission losses become too high, and the required cabling mass is incompatible with launch constraints. In addition, the power infrastructure must achieve exceptional reliability and rely on radiation tolerant components. Radiation hardened high voltage GaN technology is currently the only practical solution capable of closing this technological gap and enabling the power system architectures required for long term human operations on the lunar surface and beyond.
