1 Scope

In general terms, the scope of the consolidation of LCLs power distribution interface requirements in the 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.
