AC-DC Rectifier

The capacitor in parallel with the load keeps a steady flow of current during the AC's 0 degree phase. So it's basically mimicking DC.

This circuit is good in theory only, it has many short comings, the size of the transformer alone would be one of these.

@serge, I think billyt meant the transformer is unrealistic, and now you made it more so by reducing the number of turns on it. You can have whatever ratio you want, that is determined by n_2/n_1. Where n is the number of turns and the numbers correlate to the primary or secondary. If you multiple that ratio by the input voltage that is your voltage out. With that being said, if you have ever looked at a transformer they have more than say one or two turns on them... so like billyt said, yes theoretically and mathematically this works, it doesn't work in real life because you need more than one turn. Inductors even have more than one turn.

Thanks
