A power distribution system for the AMS experiment on the international space station

Abstract

The Alpha Magnetic Spectrometer ( AMS) experiment on the International Space Station ( ISS) requires a fully redundant, highly efficient, space qualified power distribution system. The device receives up to 2.8 kW of electrical power from the ISS and distributes it to the various subsystems of the experiment. The majority of these subsystems require the power to be converted from the ISS delivered nominal voltage level of 120 VDC to 28 VDC. The entire system and the individual output channels will be monitored and controlled from the Control Centers on the ground.
