Abstract
Work contributing to the development of a 2 kW power subsystem for a future Spacelab microgravity platform is reported. Power transfer through a single-turn floating isolation transformer allows physical independence between Spacelab and the platform. Resonant techniques are used to nullify leakage inductance effects. A power system, based on a single 28 V, 72 A series-resonant converter, and to be realized in space-qualified hybrid technology. achieves an overall efficiency greater than 88% with an efficiency of 94% for the power inverter
