The increasing demands for additional power from on-board fighting vehicles power plants is causing an urgent need for more efficient and intelligent power distribution. This strongly motivates investigation into improving the power distribution capabilities of vehicle power units. The goal of Phase I is to demonstrate the impressive improvements in the power distribution system for fighting vehicles that can be gained by transitioning to Gallium Nitride (GaN) power devices that provide for 28VDC circuit protection, will be capable of distributing up to 20A on each of 32 channels, and have ability to parallel channels to deliver up to 300A output to loads on demand. Our research team will combine our extreme energy density power technology develop at QorTek for military customers, our WBG device enabled power electronic and digital control system expertise, the proven track record of fielding ruggedized ground vehicle systems at Compass Systems Inc., and the expertise and WBG GaN devices supplied by EPC. The focus of the program will be equally split between function (performance, capability, and feature) and form factor (packaging, thermal management and ruggedization) so that the end product will meet MIL-STD 1275E, 810G, and 461.
