While space is using solar energy and batteries storage since decades, a short introduction on the constraints induced by the space environment is necessary to understand the specificities of the flown solutions. The first part of the presentation will give a general overview of main space power converters topologies and the regulation principles. Alphabus, the newly developed 22kW payload telecommunication platform, will serve as the basis of the most concrete part of the presentation. The Alphabus batteries, solar arrays will be presented, but more emphasis will be given on the main regulator and the achieved performances. Future developments in batteries and solar cells, and breadboard testing results of a GaN buck regulator will close our presentation, but open the door to future research and development activities.
