A high voltage power supply concept has been developed for the supply of an array of multiple micro-Newton thrusters for Field Emission Electric Propulsion (FEEP). For this purpose a total number of 96 high voltage conditioners are aligned in 16 centralized electronic modules. A programmable output voltage of 2.5-10.5 kV can be provided with an efficiency >88%. Zero-current switching technology is used in a resonant topology. In addition, supplementary regulated voltages of 1.0-1.5W for all thruster units are provided by a separate power conditions system A prototype model of one main supply chain has been built and characterized. Excellent dynamic behaviour with 2ms load step setting has been demonstrated.
