prBAS CEN/TR 17603-20-20:2025

In general terms, the scope of the consolidation of LCLs power distribution interface requirements in the EN 16603-20-20 (equivalent to ECSS-E-ST-20-20) and the relevant explanation in the present handbook is to allow a more recurrent approach for the specific designs offered by power unit manufacturers, at the benefit of the system integrators and of the Agency, thus ensuring: - better quality, - stability of performances, and - independence of the products from specific mission targets. A recurrent approach enables power distribution manufacturing companies to concentrate on products and a small step improvement approach that is the basis of a high quality industrial output. In particular, the scope of the present handbook is: - to explain the principles of operation of power distribution based on LCLs, - to identify important issues related to LCLs, and - to give some explanations of the requirements set up in the ECSS-E-ST-20-20 for power distribution based on LCLs, for both source and load sides.
