A single integrated & modular unit to power the EUROSTAR 3000 communication satellite
The Power Supply Regulator (PSR), developed in the frame of the new EUROSTAR 3000 telecommunication satellite, is in charge of powering the spacecraft from solar array panel in sunlight mode and from 2 batteries during eclipse.
Its power handling capacity ranges between 3 to 8.5 kW for the current 50 volt version, and will be doubled with the 100 volt version currently in development.
The PSR design is based on a modular approach in order to cope with specific mission requirements by minimizing the non- recurring costs. Its internal architecture is designed to comply with the reliability target with a single unit per spacecraft.
The PSR delivers a fully regulated 50V power bus and performs the following main functions
Made-up with two main parts, the PSR is versatile and can be adapted to mission from 3 to 8.5 kW:
The 100V version currently in development will double this value.
