- Sections and slides rewritten in Swedish; German law and institutions replaced by Swedish/CEPT/ITU equivalents (PTS, SSA, PTSFS 2025:1, SSMFS 2008:18), unverified statements marked "% TODO VERIFY" - New toc: INSTEG, HAREC, UPPGRADERING; section idents are Swedish (see ident-map.tsv) - Exam-question tags, BNetzA question pool, solutions and the German SWL course removed - Static pages, snippets, applets, READMEs and image alt-texts translated - TikZ labels translated; SVG drawings regenerated (drawing 689 still fails to build upstream: it references a missing photo) - Changed from the original: not endorsed by DARC e.V., SSA or PTS Co-Authored-By: Claude Sonnet 5.5 <[email protected]>

* Med laddningskondensator $C_L$ och LC-filter med $C_S$
|
|
* Mindre amplituder på den pulserande likspänningen
|
|
* Kondensatorerna laddas upp till sekundärsidans topspänning

#### Lösningsgång
|
|
* givet: $U_P = \qty{230}{\volt}$
|
|
* givet: $ü = 8:1$
|
|
* givet: $U_D = \qty{0,6}{\volt}$
|
|
* sökt: $\hat{U}$

|
|
$ü = \frac{U_P}{U_S} \Rightarrow U_S = \frac{U_P}{ü} = \frac{\qty{230}{\volt}}{8} = \qty{28,75}{\volt}$

I tomgång kan diodspänningen försummas.
|
|
$\hat{U} = U_S \cdot \sqrt{2} = \qty{28,75}{\volt} \cdot 1,41 \approx \qty{40}{\volt}$
