For the provided voltage rectifier assume a constant voltage

drop model with V$\_($D$)=0\mathrm{.}5$V for all diodes.

Find the required amplitude V$\_($S$)$ such that the average

voltage V$\_(0)^(+)$is $18$ V $.$

Determine the transformer winding ratio N for V$\_($AC$)=\backslash$omega t V$\_(0)^(-)$be for the selected

design.
