Space Station Freedom power management and distribution design status

The design status of the power management and distribution electric power system for the Space Station Freedom is presented. The design is a star architecture, which has been found to be the best approach for meeting the requirement to deliver 120 V DC to the user interface. The architecture minimizes mass and power losses while improving element-to-element isolation and system flexibility. The design is partitioned into three elements: energy collection, storage and conversion, system protection and distribution, and management and control. >
