The High Power Linear Alternator Test Rig will be used to develop Power Management and Distribution (PMAD) techniques applicable to a lunar power system. The PMAD consists of the control algorithms and power electronics required for the conversion of a single phase AC output of the Stirling alternator to a regulated DC voltage for use in lunar applications. The task will include simulated power transmission over a few hundred meters, rectification, filtering and regulation of the AC output, distribution of the power to simulated loads, and control of the Stirling power convertor piston amplitude. Testing will determine the power quality of the DC output voltage, the transient response, the system efficiencies and mass.
