\begin_layout Section
Ausgangsspannung der PSU:
\end_layout

\begin_layout Standard
Richtig dimensionieren weil:
\end_layout

\begin_layout Itemize
zu hoch: spannung wackelt, unruhe am verstärker
\end_layout

\begin_layout Itemize
zu niedrig: PSU verbrennt unnötig Leistung, Verstärker hat weniger Headroom
\end_layout

\begin_layout Standard
Verfügbare Spannung des Trafo: 
\begin_inset Formula $V_{\sim}\cdot\sqrt{2}=42.42V$
\end_inset


\end_layout

\begin_layout Standard
Spannungsabfälle unter Volllast (5A):
\end_layout

\begin_layout Itemize
2*0.8V Gleichrichterdioden
\end_layout

\begin_layout Itemize
2V LM317
\end_layout

\begin_layout Itemize
0.7V Basis des Leistungstransistors
\end_layout

\begin_layout Itemize
2.84V Hub am Kondensator (
\begin_inset Formula $5A\cdot10ms/17.6mF$
\end_inset

)
\end_layout

\begin_layout Itemize
Innenwiderstand des Trafos, sagen wir 15% (6.3V)
\end_layout

\begin_layout Itemize
Sicherheitsabstand, sagen wir 2V
\end_layout

\begin_layout Standard
=> 27V
