When actually building the designed rectifier, how should I modify the theoretical values, for example if the theoretical capacitance is 18.65uF, should I use a 15uF capacitor or a 20uF one? and why?

The same question for the turn ratio of the transformer.


Thanks a lot!

If you use a higher value. You will expect to get less ripple. And that is always wanted in such application. More ripple may cause trouble. So in this case it is correct to round up.

The opposite occurs with the turns ratio of the transformer. If you are stepping down the voltage, going to a higher turns ratio will result in a lower output voltage. If you want to maintain a minimum output voltage, you want to increase the output voltage, not lower it.
