Space engineering - Guidelines for electrical design and interface requirements for power supply

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.

Na splošno naj bi konsolidacija zahtev za vmesnike za distribucijo električne energije LCL v standardu EN 16603-20-20 (enakovreden dokumentu ECSS-E-ST-20-20) in ustrezna razlaga v tem priročniku omogočili ponavljajoči se pristop za posebno projektiranje, ki ga ponujajo proizvajalci pogonskih enot, v korist sistemskih integratorjev in Agencije, s čimer se zagotovi:
– večja kakovost,
– stabilnost delovanja in
– neodvisnost izdelkov od ciljev posameznih misij.
Ponavljajoči se pristop podjetjem za proizvodnjo električne energije omogoča, da se osredotočijo na izdelke in pristop k izboljšanju z majhnimi koraki, ki je osnova za visokokakovostno industrijsko proizvodnjo.
Področje uporabe tega priročnika vključuje zlasti:
– razlago principov delovanja distribucije električne energije na osnovi LCL,
– prepoznavanje pomembnih vprašanj, povezanih z LCL, in
– nekaj razlag zahtev, določenih v dokumentu ECSS-E-ST-20-20 za distribucijo energije, ki temelji na LCL, tako na strani vira kot obremenitve.
